Abstract:

The multi-phase inverter modulation and control method is a hotspot of multiphase systems. There is no general space vector modulation available due to the inherent difficulty in synthesizing more than one independent space vector simultaneously in different d-p planes. This paper established the distribution model of five-phase inverter space vector from a novel perspective of magnetic motive force (MMF) equivalence. And then a multi-dimensional SVPMW method applicable to the non-sinusoidal voltage output was proposed based on the obtained space vector distribution laws. The proposed multi-dimensional SVPWM method effectively improves the fundamental modulation range and is suitable for five-phase inverter non-sinusoidal modulation.

<p>This paper presents new modified space vector pulse width modulation techniques (Phase disposition-Space vector pulse width modulation, Alternative Phase Opposition disposition- Space vector pulse width modulation and Phase Opposition disposition-Space vector pulse width modulation) are analyzed for three-phase cascaded multi-level inverter fed induction motor from the point of view of the Phase voltages, line voltage, stator current,speed,torque and Total harmonic distortion.in the proposed modified technique the reference signals are generated by adding offset voltage to the reference phase voltages.This modified SVPWM technique does not involve region indentification,sector identification for switching vector determination as are required in the conventional multi level SVPWM technique,it is also reduces the computation time compared to the conventional space vector PWM technique.The necessary calculations for generation of new modified SVPWM for the modulation strategies have presented in detail. It is observed that the modified SVPWM modulation ensures excellent, close to optimized pulse distribution results and THD is compared to for five-level, seven-level, nine-level and eleven-level Cascaded H-Bride Multi-level Inverter fed to Induction motor. Theoretical investigations were confirmed by the digital simulations using MATLAB/SIMULINK software.</p>

Abstract:

Nowadays, transformer-less photovoltaic (PV) multi-level inverters (MLIs) are commonly employed in both industrial and residential settings. This structure has attracted increased attention due to its unique advantages, such as higher efficiency, lower cost and size, better waveform quality, and inherent fault tolerance. However, due to the removal of the transformer, the common mode voltage (CMV) becomes one of the crucial issues in transformer-less PV MLIs. The high-frequency variation in CMV results in a leakage current that deteriorates the line current quality, increases the PV power system losses, leads to severe electromagnetic emissions (EMI), reduces the PV array lifespan, and causes personal safety problems. In this regard, this paper presents a review of the existing and recent research on modulation techniques based on space vector pulse width modulation (SVPWMs) that overcome this issue in transformer-less three-level NPC-MLIs (3L-NPC-MLIs). The reduced CMV-SVPWM (RCMV-SVPWM) can be mainly categorized as an RCMV-SVPWM based on the vector type, based on virtual vectors, and based on the two-level SVPWM (2L-SVPWM). Their features and their limitations in terms of several main criteria are discussed. In the final section of this paper, some challenges and future trends for this research area are projected.

Abstract:

Considering that the defects of traditional nearest–two–vector SVPWM (NTV–SVPWM) have a low voltage transfer ratio (VTR) and those of nearest–four–vector SVPWM (NFV–SVPWM) have a high output current harmonic, two improved space–voltage pulse–width–modulation (SVPWM) strategies are proposed in this paper, based on analyzing the harmonic characteristics of traditional NTV–SVPWM and NFV–SVPWM. The first strategy is to synthesize the referenced voltage vector according to the different weight factors by NTV–SVPWM and NFV–SVPWM. The second strategy is to synthesize the referenced voltage vector according to the different weight factors of NFV–SVPWM and the large vector. Compared to NTV–SVPWM, the simulation results show that the two proposed SVPWM strategies have lower output voltage errors and THDs. Compared to NFV–SVPWM, the simulation results show that the two proposed SVPWM strategies have higher VTRs and THDs. Compared to the two proposed SVPWM strategies, proposed SVPWM strategy one has a lower output voltage error and THD. The experimental results verify that the proposed modulation strategy is correct and feasible.

Abstract:

This paper proposed an artificial neural network (ANN) based space vector pulse width modulation (SVPWM) for motor drive which fully covers the undermodulation and overmodulation regions. A neural network has the advantage of very fast implementation of an SVPWM algorithm that can increase the converter switching frequency, particularly when a dedicated application-specific integrated circuit chip is used in the modulator. Finally, in the environment of MATLAB/Simulink with the Neural Network Toolbox builds the simulation model of system with proposed ANN-SVPWM controller. The simulation results show that the performances of the motor drive with artificial-neural-network-based SVPWM are excellent.

Abstract:

In the five-phase-inverter adjustable speed system, a five-phase two-level inverter usually adopts the nearest-two vector SVPWM (NTV-SVPWM) or the nearest-four vector SVPWM (NFV-SVPWM). The former one has a high-output-current harmonic, which increases the power losses, while the latter one has a low harmonic, but its sinusoidal voltage transfer ratio (VTR) is 0.812, which decreases load capacity. To improve the loading capacity and decrease the power losses of the five-phase-inverter adjustable speed system, a new space vector over-modulation method based on multi-vector weighting is proposed in this paper, and harmonic characteristics of the proposed over-modulation method are analyzed. The simulation results indicate that the proposed over-modulation method has a lower output voltage error than that with the traditional NFV-SVPWM and has a lower output current THD than that with the traditional NTV-SVPWM. The experimental results verify that the proposed method is correct and feasible.

Abstract:

Space Vector Pulse Width Modulation (SVPWM) can use the power supply with high efficiency. However, the traditional SVPWM algorithm has the disadvantage of complex calculation. At the same time, the low frequency causes the motor to generate pulsating torque, which has high switching frequency, large power loss and other shortcomings. Aiming at the deficiencies of traditional SVPWM modulation, a new SVPWM algorithm for insertion of zero vector is designed in this review. Under the condition that the waveform quality is guaranteed, the power loss of the switch is reduced and the low frequency is enhanced. And MATLAB simulation is used to simulate and verify the correctness of this method.

Abstract:

A simulation analysis of a voltage source inverter using Space Vector Pulse Width Modulation (SVPWM) to control the speed of a Permanent Magnet Synchronous Motor (PMSM) has been presented in this research. PMSM is an AC drive that widely helps in high power propulsion systems. SVPWM is one of the best PWM techniques. The SVPWM is powered by a voltage source inverter connected to the PMSM. Space vector modulation is responsible for developing pulses to control the switches of the inverter.

Abstract:

Pulse modulation width (PWM) of multi-phase inverter is the key technologies of ships electrical propulsion. In this paper, theories and realization of space vector PWM (SVPWM) for five-phase inverter is analyzed. The proposed SVPWM adopts two adjacent large voltage vectors to composite the reference voltage vector and this method have advantages of easy to realize. Theoretical waveform and harmonics of five-phase inverter output voltages under the proposed control method are deduced. The analysis shows that there are very large third harmonics in the inverter output voltages and currents. The total harmonic distortion (THD) is large also, and changes small with the modulation index. Simulation and experiments certify the conclusions.

Abstract:

This thesis aims to design and build a power electronics system for the rectification and control of magnetization currents in synchronous generators with rotating exciters.The rotating exciter provides three-phase AC while the generator rotor needs DC with a high degree of control. The system needs to be able to rectify the three-phase AC to a stable DC without unwanted harmonic content, neither on the DC or the AC side. For control purposes it is also important that the current in the rotor can be changed very swiftly, preferably by several amperes during a single revolution ofthe machine.The system of choice is a synchronous rectifier bridge consisting of six MOSFET switches operated using the Space vector pulse width modulation (SVPWM) algorithm. This method gives a stable and controllable DC voltage while it keeps the harmonic content of the input currents at a minimum. However the DC voltage will always be higher than the peak line-to-line voltage from the exciter. To be able to lower the voltage below this value a Buck-converter is placed after the rectifier bridge.To gain a higher degree of control of the current density in the rotor windings the windings have been subdivided into three parts. To provide individual control of the current in the three rotor parts each part have been outfitted with a Push and Pull H-bridge.The proposed system has been both simulated using MATLAB Simulink and built and tested in the laboratory with satisfactory results.<br>I detta examensarbete presenteras ett kraftelektroniksystem för förbättrad kontroll av magnetiseringsstömmar i vattenkraftsgeneratorer som är utrustade med roterande matare.Generatorer används för att konvertera energi från rörelseenergi till elektrisk energi. Detta görs genom att man utsätter spolar för varierande magnetfält; då induceras spänning i spolarna. I vattenkraftsgeneratorer används oftast stora elektromagneter placerade i en rotor för att skapa dessa magnetfält. För att magnetisera elektromagneterna behövs ström som på något sätt måste överföras mellan den statiska och den roterande sidan i generatorn. Traditionellt görs detta med hjälp av släpringar och kolborstar som genom mekanisk kontakt överför elektriciteten. En roterande matare kan beskrivas som en liten generator som har sina elektriska utgångar på den roterande sidan istället för på den statiska sidan. Genom att placera en roterande matare på samma axel som den stora generatorn kan man istället alstra den elektricitet som behövs för att magnetisera generatorn direkt på den roterande sidan. Däregenom undviks många problem som är associerade med lösningen med släpringar.Den roterande mataren ger dock växelström medan magnetiseringsströmmen måste vara likström. Det är här kraftelektroniken kommer in i bilden. Det finns flera sätt att åstadkomma likriktning av ström. I det här projektet har ett fullständigt aktivt system byggts. Systemet är uppbyggt av transistorer av MOSFET typ och kan kontrolleras trådlöst med hjälp av Bluetoothteknik. Systemet ger full kontroll över strömmar och spänningar både på växelströmssidan och på likströmssidan och ska användas till en testgenerator på avdelningen för ellära vid Uppsala Universitet. Där ska den utökade kontroll som systemet ger förutsättningar till användas för att undersöka hur den här typen av system kan optimera de magnetiska krafterna inuti generatorn. En sådan optimering kan minska vibrationerna i generatorn och därigenom minska slitaget på lager och andra delar i maskinen.

Abstract:

A voltage source inverter is commonly used to supply a variable frequency variable voltage to a three phase induction motor in a variable speed application. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter. Real-time methods for PWM generation can be broadly classified into triangle comparison based PWM (TCPWM) and space vector based PWM (SVPWM). In TCPWM methods such as sine-triangle PWM, three phase reference modulating signals are compared against a common triangular carrier to generate the PWM signals for the three phases. In SVPWM methods, a revolving reference voltage vector is provided as voltage reference instead of three phase modulating waves. The magnitude and frequency of the fundamental component in the line side are controlled by the magnitude and frequency, respectively, of the reference vector. The fundamental line side voltage is proportional to the reference magnitude during linear modulation. With sine-triangle PWM, the highest possible peak phase fundamental voltage is 0.5Vdc, where Vdc is the DC bus voltage, in the linear modulation zone. With techniques such as third harmonic injection PWM and space vector based PWM, the peak phase fundamental voltage can be as high as (formula) (i.e., 0:577Vdc)during linear modulation. To increase the line side voltage further, the operation of the VSI must be extended into the overmodulation region. The overmodulation region extends upto the six-step mode, which gives the highest possible ac voltage for a given (formula). In TCPWM based methods, increasing the reference magnitude beyond a certain level leads to pulse dropping, and gradually leads to six-step operation. However, in SVPWM methods, an overmodulation algorithm is required for controlling the line-side voltage during overmodulation and to achieve a smooth transition from PWM to six-step mode. Numerous overmodulation algorithms have been proposed in the literature for space vector modulated inverter. A well known algorithm among these divides the overmodulation zone into two zones, namely zone-I and zone-II. This is termed as the 'existing overmodulation algorithm' here. This algorithm is modified in the present work to reduce computational burden without much increase in the line current distortion. During overmodulation, the fundamental line side voltage and the reference magnitude are not proportional, which is undesirable from the control point of view. The present work ensures a linear relationship between the two. Apart from the fundamental component, the inverter output voltage mainly consists of harmonic components at high frequencies (around switching frequency and the integral multiples) during linear modulation. However, during overmodulation, low order harmonic components such as 5th, 7th, 11th, 13th etc., are also present in the output voltage. These low order harmonic voltages lead to low order harmonic currents in the motor. The sum of the lower order harmonic currents is termed as 'lower order current ripple'. The present thesis proposes a method for estimation of lower order current ripple in real-time. In closed loop current control, the motor current is fed back to the current controller. During overmodulation, the motor current contains low order harmonics, which appear in the current error fed to the controller. These harmonic currents are amplified by the current error amplifier deteriorating the performance of the drive. It is possible to filter the lower order harmonic currents before being fed back. However, filtering introduces delay in the current loop, and reduces the bandwidth even during linear modulation. In the present work, the estimated lower order current ripple is subtracted from the measured current before the latter is fed back to the controller. The estimation of lower order current ripple and the proposed current control are verified through simulation using MATLAB/SIMULINK and also experimentally on a laboratory prototype. The experimental setup comprises of a field programmable gate arrays (FPGA) based digital controller, an IGBT based inverter and a four-pole squirrel cage induction motor.

Approved for public release; distribution is unlimited<br>Alternating current motors are used throughout the fleet because of their rugged construction and nearly maintenance free operation. Since the U.S. Navy is exploring and acting on the possibilities of DC distribution systems, the need exists for simple, reliable three-phase voltage source inverter (VSI) powered induction machines. Until recently, VSIs utilized a pulse width modulation (PWM) scheme controlling the frequency and amplitude of each phase. A novel and simple hardware centered VSI controller was designed, simulated, built and tested featuring a type of space vector modulation (SVM). Design criteria evaluated such as VSI frequency response, switching losses, dead-time and SVM switching sequences were considered. Specifically, modulo-6 and 12 synthetic SVM units were evaluated for future Department of Defense use.

Abstract:

L’impact des stratégies Modulation de Largeur d'Impulsion (MLI) sur les sollicitations des condensateurs de découplage en entrée d’un onduleur triphasé est bien connu à l’heure actuelle au même titre que le comportement de la charge alimentée (facteur de puissance). On dispose à l’heure actuelle d’un large panel de techniques de modulation applicables en fonction des diverses contraintes d’environnement (stress des condensateurs mais aussi qualité des courants dans la charge ou pertes par commutation dans les semi-conducteurs). Toutefois, dans de nombreux contextes applicatifs, le bus continu peut être mutualisé entre plusieurs convertisseurs qui vont solliciter individuellement le ou les condensateurs de découplage. L’objectif de cette thèse est d'étudier la mise en œuvre des stratégies MLI coordonnées entre plusieurs onduleurs mutualisant leur bus continu. Plus précisément, une étude du cas des convertisseurs back-to-back dans le cas de MADA a été faite. De plus, cette étude vise à évaluer l'impact de stratégies MLI entrelacées sur le courant efficace traversant le condensateur de découplage associé à deux convertisseurs en parallèle. En effet, cette valeur est généralement le paramètre clé pour le dimensionnement de ce (ou ces) composant(s), bien au-delà de la capacité, notamment pour les condensateurs électrolytiques à l'aluminium. La technique d'entrelacement est appliquée selon deux stratégies différentes : - La stratégie classique SVPWM ; - La stratégie MLI à double porteuse unifié (Uni-DCPWM) qui est dédié à la réduction du courant efficace pour un seul convertisseur. Notre étude vise également à réduire le courant RMS dans le condensateur et à trouver la valeur optimale du temps d'entrelacement de manière dynamique pour tous les points de fonctionnement<br>The impact of Pulse Width Modulation (PWM) strategies on the stresse of the decoupling capacitors at the input of a three-phase converter is currently well known, as well as the behavior of the supplied load (power factor). A large panel of modulation techniques is currently available and can be applied according to the various environmental constraints (stress on the capacitors but also quality of the currents in the load or switching losses in the semiconductors). However, in many application contexts, the DC bus can be shared between several converters that will individually stress the decoupling capacitor(s). The objective of this thesis is to study the implementation of PWM strategies between several converters sharing their DC bus. More precisely, a study of the case of back-to-back converters connected on Doubly Fed Induction Machine (DFIM) has been done. The aim of this study is to evaluate the impact of interleaved PWM strategies on the RMS current flowing through the DC link capacitor associated to two back-to-back three-phase Full Bridges (FB). Indeed, this value is usually the key-parameter for the sizing of this (or these) component(s), far above the capacitance, especially for aluminum electrolytic capacitors. Interleaving technique is applied on two different strategies: - Classical (single carrier) Space-Vector PWM strategy (SVPWM) ; - Unified Double Carrier PWM (Uni-DCPWM) that is dedicated to the reduction of the RMS current for a single FB. Our study also aims to reduce the RMS current in the capacitor and find the optimal value of the interleaving time dynamically for all operating points

Abstract:

The dissertation documents research work carried out on Pulse Width Modulation (PWM) strategies for hard switched Voltage Source Inverters (VSI) for variable speed electric drives. This research is aimed at Hybrid Electric Vehicles (HEV). PWM is at the heart of all variable speed electric drives; they have a huge influence on the overall performance of the system and may also help eventually give us an extra degree of freedom in the possibility to rethink the inverter design including the re-dimensioning of the inverter components.HEVs tend to cost more than conventional internal combustion engine (ICE) vehicles as they have to incorporate two traction systems, which is the major discouraging factor for consumers and in turn for manufacturers. The two traction system increases the maintenance cost of the car as well. In addition the electric drives not only cost extra money but space too, which is already scarce with an ICE under the hood. An all-electric car is not yet a viable idea as the batteries have very low energy density compared with petrol or diesel and take considerable time to charge. One solution could be to use bigger battery packs but these add substantially to the price and weight of the vehicle and are not economically viable. To avoid raising the cost of such vehicles to unreasonably high amounts, autonomy has to be compromised. However hybrid vehicles are an important step forward in the transition toward all-electric cars while research on better batteries evolves. The objective of this research is to make electric drives suitable for HEVs i.e. lighter, more compact and more efficient -- requiring less maintenance and eventually at lower cost so that the advantages, such as low emissions and better fuel efficiency, would out-weigh a little extra cost for these cars. The electrical energy source in a vehicle is a battery, a DC Voltage source, and the traction motor is generally an AC motor owing to the various advantages it offers over a DC motor. Hence the need for a VSI, which is used to transform the DC voltage into AC voltage of desired amplitude and frequency. Pulse width modulation techniques are used to control VSI to ensure that the required/calculated voltage is fed to the machine, to produce the desired torque/speed. PWM techniques are essentially open loop systems where no feedback is used and the instantaneous values differ from the required voltage, however the same average values are obtained. Pulse width modulated techniques produce a low frequency signal (desired average value of the switched voltage) also called the fundamental component, along with unwanted high frequency harmonics linked to the carrier signal frequency or the PWM period. In modern cars we see more and more mechanical loads driven by electricity through digital processors. It is very important to eliminate the risk of electromagnetic interference between these systems to avoid failure or malfunction. Hence these unwanted harmonics have to be filtered so that they do not affect the electronic control unit or other susceptible components placed in the vicinity. Randomised modulation techniques (RPWM) are used to dither these harmonics at the switching frequency and its multiple. In this thesis a random modulator based on space vector modulation is presented which has additional advantages of SVM. Another EMI problem linked to PWM techniques is that they produce common mode voltages in the load. For electric machines, common mode voltage produces shaft voltage which in turn provokes dielectric stress on the motor bearings, its lubricant and hence the possibility of generating bearing currents in the machine that can be fatal for the machine. To reduce the common mode voltage a space vector modulation strategy is developed based on intelligent placement of zero vectors. (...)

Abstract:

This dissertation is the result of research and development of a power conditioning system for Superconductive Magnetic Energy Storage System. The dominant challenge of this research was to develop the power conditioning system that can match slowly varying dc voltage and dc current on the super conductive magnet side with the ac voltages and ac currents on the utility side. At the same time the power conditioning system was required to provide a bi-directional power flow to the superconductive magnet. The focus of this dissertation is a three-level diode clamped dc-ac converter which is a principle part of the power conditioning system. Accordingly, this dissertation deals with the space vector modulation of three-level converters and introduces a computationally very efficient three-level space vector modulation algorithm that is experimentally verified. Furthermore, the proposed space vector modulation algorithm is successfully generalized to allow equally efficient, real time implementation of space vector modulation to dc-ac converters with virtually any number of levels. The most important advantage of the proposed concept is in the fact that the number of instructions required to implement the algorithm is almost independent from the number of levels in a multilevel converter. More on the side of the control of multilevel converters, the particular attention in this dissertation is paid to the problem of charge balance in the split dc-link capacitors of three-level neutral-point-clamped converters. It is a known fact that although the charge balance in the neutral point can be maintained on a line cycle level, a significant third harmonic current flows into the neutral point for certain loading conditions, causing the neutral point voltage ripple. The logical consequence of that ripple is the deteriorated quality of the output voltage waveforms as well as the increased voltage stress on the switching devices. This was the motivation to more carefully explore the loading conditions that cause the unbalance, as well as to study the fundamental limitations of dc-link capacitor charge balancing algorithms. As a part of that work, a new model of the neutral point current in the rotating coordinate frame is developed as a tool in investigation of theoretical limitations and in providing some intuitive insight into the problem. Additionally, the low frequency ripple is quantified and guidelines are offered that can help size the dc-link capacitors. Because the study of the neutral point balance identified the loading conditions, that under some possible system constraints, cause an unavoidable neutral point voltage ripple, a feed forward type of control method is developed next. The proposed feed forward algorithm can effectively prevent the neutral point voltage ripple from creating distortions in the converter output voltage under all loading conditions and without causing additional disturbance in the neutral point voltage. The feed forward method is developed for a sine triangle as well as for the space vector type PWM algorithm. The simulation results that include the full dynamic model of the converter and load system validate the feed forward approach and prove that the feed forward algorithm can effectively compensate the effect of the neutral point voltage ripple. The simulation results are than experimentally verified.<br>Ph. D.

Abstract:

This thesis covers the investigation into the use of Space Vector Modulation for the control of a 4-leg matrix converter, which is capable of providing a 3-phase plus neutral supply from a standard balanced 3-phase source. Traditional 3x3 matrix converters have limited use in this application as they are only capable of supplying a balanced three-phase load. It would be desirable to be able to power unbalanced and non-linear loads, requiring that the converter provides a neutral connection. As with voltage source inverters, this goal can be achieved by extending the number of output legs in the matrix converter to four. In this thesis, a new Space Vector Modulation technique is proposed for this 4-leg, or 3x4, matrix converter. This technique is an extension of the method currently in use on 3x3 matrix converters, and so it allows the de-coupled control of both the input and output. The thesis then goes onto cover the build of a demonstration converter, looking at the different aspects which make up a converter, to finally go on to prove the theory, and a set of results are presented to validate this.

<div class="section abstract"><div class="htmlview paragraph">The popular methods to generate PWM (Pulse width modulation) are triangle comparison method and space vector method. The work evaluates the performance of continuous and discontinuous space vector pulse width modulation techniques based on the switching losses and harmonic distortion. The flexibility in the placement of null vectors and active vectors gives generality in SVPWM (Space Vector PWM) techniques. Continuous SVPWM employs the conventional switching sequences which are equally divided the null vectors and active vectors. Discontinuous PWM are derived based on the different combinations of null and active switching vectors. The discontinuous PWM techniques clamps each phase for either 300 or 600 in each half cycle. Majority of the discontinuous SVPWM uses any one of the null vectors and effectively to reduce the average switching loss in a cycle and the total harmonic distortion.The study brings out the optimum SVPWM sequences for the control of PMSM(PERMENANT MAGNET SYNCHRONOUS MACHINE). Influence of the switching sequences on the line current distortion is investigated. The performance of inverter based on switching loss and harmonic distortion are studied based on the switching frequency of the inverter over the linear modulation range.

Abstract:

Power quality issues are a major concern in modern electrical grids, particularly with the increasing integration of renewable energy sources and sensitive electronic equipment. Dynamic Voltage Restorers (DVR) have emerged as a potent solution for mitigating voltage sags, swells, and interruptions. This paper introduces a novel approach to enhance power quality using a Z-source inverter (ZSI) based DVR, employing Space Vector Pulse Width Modulation (SVPWM) techniques. The ZSI offers unique advantages in this application, including the ability to boost voltage without the need for additional DC-DC converters and the capability to operate under various load conditions. We present a comprehensive design and simulation of the SVPWM Z-source inverter, detailing its configuration, control strategy, and integration within a DVR system. Simulation results demonstrate that the proposed DVR configuration effectively compensates for voltage disturbances, thereby stabilizing the load voltage and improving the overall system performance. Comparative analyses highlight the superiority of the Z-source inverter over traditional inverter designs, showing significant improvements in efficiency and reliability. This study confirms that SVPWM Z-source inverter based DVRs can offer a robust and efficient solution for enhancing power quality in contemporary power systems.

Abstract:

<div class="section abstract"><div class="htmlview paragraph">Electric vehicles (EV) require an electric motor with a better power density, greater efficiency, a wide constant power area, ease of control, and low costs. A real time control adapted electric motor design is necessary to meet these criteria. In this work, interior permanent magnet synchronous motor (IPMSM) design was created from Ansys rotating machine expert and 2D model was developed in Ansys Maxwell based on various design parameters for the rotor and stator configuration, and the electromagnetic (EM) simulations are carried out in accordance with the essential required EV characteristics. Using Ansys Twin Builder, a model was made for the drive circuit, proportional integral (PI) speed controller, speed references, rotor position detection, and space vector pulse width modulation (SVPWM) / sinusoidal pulse width modulation (SPWM) are used. This method demonstrates the investigation of the torque ripple and total hormonic distortion (THD) and shows the influence of SVPWM and SPWM techniques on torque ripple and THD. To realistically reflect the performance of the drive, coupled simulation of the IPMSM motor and drive with vector control system is used to analyze the IPMSM drive system through Ansys maxwell and Ansys Twin Builder environment during EM analysis. The simulation outcomes demonstrate the high feasibility of motor design and control strategy, that delivers the intended result and quick response with minimal torque ripple and distortion. According to the simulation findings at 10kHz, SVPWM technique has torque ripple 12.4% and THD in the input current and voltage to the motor are 4.0 and 38.4% respectively. But SPWM has torque ripple 28.5% and input current and voltage THD are 6.8 and 42.6% respectively. Investigation shows SVPWM method is more practical and effective for producing sine waves that deliver higher voltage and current to the load with minimal torque ripple and harmonic distortion.</div></div>

Abstract:

This paper presents a comprehensive evaluation of the performance of an interior permanent magnet (IPM) traction motor drive, and analyses the impact of different modulation techniques. The most widely used modulation methods in traction motor drives are Space vector modulation (SVPWM), over-modulation, and six-step modulation have been implemented. A two-dimensional electromagnetic finite element model of the motor is co-simulated with a dynamic model of a field-oriented control (FOC) circuit. For accurate tuning of the current controllers, extended complex vector synchronous frame current regulators are employed. The DC-link voltage utilization, harmonics in the output waveforms, torque ripple, iron losses, and AC copper losses are calculated and compared with sinusoidal excitation. Overall, it is concluded that the selection of modulation technique is related to the operating condition and motor speed, and a smooth transition between different modulation techniques is essential to achieve a better performance.
