Abstract:
In this paper two very efficient pulse width modulation techniques were discussed named Sin pulse width modulation and space vector pulse width modulation. The basic structure of the three-level inverter neutral-point clamped is introduced and the basic idea about space vector pulse width modulation for three-level voltage source inverter has been discussed in detail. Nearest three vectors space vector pulse width modulation control algorithm is adopted as the control strategy for the three phase three level NPC inverter in order to compensate the neutral-point shifting. Mathematical formulation for calculating switching sequence has determined. Comparative analysis proving superiority of the space vector pulse width modulation technique over the conventional pulse width modulation, and the results of the simulations of inverter confirm the feasibility and advantage of the space vector pulse width modulation strategy over sin pulse width modulation in terms of good utilization of dc-bus voltage, low current ripple and reduced switching frequency. Space vector pulse width modulation provides advantages better fundamental output voltage and useful in improving harmonic performance and reducing total harmonic distortion.

Abstract:
This research presents a generic pulse width modulation (PWM) approach for nine switch inverters and five-leg inverters. The circuit design of both inverters and a modulation mechanism for separate drives have been described. The available DC bus voltage supplied the two induction motors using a PWM technique for a 5-leg inverter. Nine-switch inverters and nine-switch z-source inverters have lately been presented as dual-output inverter. A nine-switch z-source inverter and a unique pulse width modulation (PWM) were created. Also, a five-leg inverter is modelled using Extended Two Arm Modulation (ETAM) scheme. The suggested modulation techniques were applied to control two machine drive systems with a single inverter architecture with a reduced switch count for pumping the water to house hold appliances. The comparative analysis of the two dual-output inverters is integral to this work.

Abstract:
The popularity of multilevel inverters have increasing over the years in various applications without use of a transformer and has many benefits. This work presents the performance and comparative analysis of single phase diode clamped multilevel inverter and a hybrid inverter with reduced number of components. As there are some drawbacks of diode clamped multilevel inverter such as requiring higher number of components, PWM control method is complex and capacitor voltage balancing problem, an implementation of hybrid inverter that requires fewer components and less carrier signals when compared to conventional multilevel inverters is discussed. The performance of single phase diode clamped multilevel inverter and hybrid multilevel inverter for seven, nine and eleven levels is performed using phase disposition, alternate phase opposition disposition sinusoidal pulse width modulation techniques. Both the multilevel inverter are implemented for the above mentioned multicarrier based Pulse Width Modulation methods for R and R-L loads. The total harmonic distortion is evaluated at various modulation indices. Theanalysis of the multilevel inverters is done by simulation in matlab/simulink environment.

Abstract:
In this paper, two types seven-level multilevel inverters in three phase configuration, Cascaded H-bridge Multilevel Inverter (CMLI) and Diode Clamped Multilevel Inverter (DCMLI) are simulated and compared the results for three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Disposition technique (PD), Phase Opposition Disposition technique (POD), and Alternate Phase Opposition Disposition technique (APOD). In all the modulation strategies, triangular carrier and trapezoidal triangular carrier signals are compared with reference signal for generation of control pulses. The simulations have been carried out for seven-level CMLI and DCMLI using MATLAB/Simulink. The detailed analysis of results in terms of %THD and utilization of DC-link voltage has been presented in this paper. By increasing the performance of inverters the utilization of input energy is reduced, then the corresponding energy sources can be reduced.

Abstract:
Voltage source inverter has been applied for uninterruptible power supply (UPS), renewable energy sources, and motor drive. The popular modulations for inverters are sinusoidal pulse width modulation (SPWM), zero sequence signal modulation (ZSS), space vector modulation (SVM), and discontinuous PWM (DPWM). All these modulations have been applied to three-phase and multiphase inverters. The characteristics of the modulation application in these inverters have been well investigated. However, only SPWM has been applied satisfactorily in single-phase inverter. From the literature, the applications of ZSS and DPWM couldn’t show any benefit. In this paper, a DPWM is proposed for single-phase inverter. The output current ripple is analyzed and experiments are conducted to verify the analytical result. Comparison to SPWM is conducted to find the modulation index range that provides a benefit when using the DPWM.

Abstract:
This article presents a carrier-based pulse-width modulation (PWM) template for a 5-level, H bridge-based cascaded multilevel inverter (MLI). The developed control concept generates adequate modulation template for this inverter topology wherein a sinusoidal modulating waveform is modified to fit in a single triangular carrier signal range. With this modulation approach, classical multiplicity and synchronization of the triangular carrier signals criterion for the extension of sinusoidal pulse-width modulation, SPWM, to several cascaded 5-level, H-bridge-based MLI topology are removed. The proposed template can be used on the inverter configuration of any level with no further control modification. Nearly even distribution of switching pulses and equalized individual cascaded cell output power were achieved with the proposed modulation scheme. Three 5-level, H-bridge-based MLI units were cascaded for 1-phase, 13-level inverter operation; simulation and experimental results are adequately presented.

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.

Abstract:
Three-phase multi-level topologies have been drawing increased attention in the past two decades. The numerous advantages of multi-level supply include: good power quality (low voltage distortion and dv/dt), good electromagnetic compatibility, operation with a lower switching frequency (lower switching losses), high voltage capability, smaller common mode (CM) voltage (reducing the stress in the motor bearings). There are various topologies of multilevel converters. The main ones are the neutral point clamped (NPC), the flying capacitor (FC) and the cascaded converters. Another alternative is the dual two-level inverter configuration supplying an open-end winding machine. This topology has received growing attention due to its simple structure. The open-end topology has the advantages that the additional diodes used in the neutral- point-clamped (NPC) voltage source inverter (VSI) are not needed, leading to a saving in the overall number of components. Furthermore, the issue of proper capacitor voltage balancing does not exist if the supply is two-level at each winding side. Application of such a dual-inverter supply (with equal DC-links) enables drive operation with voltage waveform equivalent to the one obtainable with a three-level VSI. The advantages of multi-phase variable speed drives over the three-phase ones are numerous and include an increase of fault tolerance, the possibility to have several multi-phase machines connected in series and drive them independently with a single VSI and, when the machine is equipped with a concentrated winding, other, higher harmonics can also be used to increase the developed torque. This thesis explores the possibility of combining the multi-phase and open-end- winding multi-level topologies. In particular the five-phase open-end-winding topology is considered. General properties of the five-phase AC motor drives with sinusoidal winding distribution are at first reviewed, along with the previously developed two- level space-vector modulation algorithm for a five-phase two-level VSI. A mathematical model of the converter is developed and a detailed study of the available switching states and corresponding voltage space vectors is conducted. It is shown that, due to the large number of switching states available in the topology together with the additional requirements when driving a multi-phase machine, the design of a suitable modulation scheme is extremely challenging. Three different space-vector modulation methods are proposed in the thesis. The developed methods are relatively simple to implement since they consider each inverter individually hence breaking down the problem into one of simpler complexity. The three modulation methods and the performance of the five- phase drive are verified using simulations. Finally, a laboratory prototype is described, which utilises two two-level five- phase inverters connected across an open-end-winding five-phase induction machine. The three modulation schemes are implemented using a fast prototyping control system (dSP ACE) and the performance of the modulation techniques is compared. The motor is controlled in V/fmode, in open loop. It is demonstrated that two of the methods produce multi-level output waveforms and that one method offers superior performance, with reduced converter losses.

Abstract:
Among the different multiphase ac drive solutions, one of the most widely reported in the literature is the six-phase machine. The machines can be realised into two different configurations, symmetrical and asymmetrical. For the symmetrical configuration, the stator winding consists of two sets of three-phase windings that are spatially shifted by 60 degrees where spatial displacement between any two consecutive phases is the same and equal to 60 degrees. For the asymmetrical configuration, the two sets of three-phase windings are spatially shifted by 30 degrees. As a result, the spatial shift between consecutive phases becomes non-equidistant. In this thesis, modulation techniques for both symmetrical and asymmetrical six-phase machines are investigated. The machines are configured in open-end winding configuration where both ends of the stator winding are connected to separate isolated inverters in a topology known as dual-inverter supply. Compared to conventional single-sided supply topology where one end of the winding is connected to an inverter while the other side is star-connected, some additional benefits are offered by the dual-inverter supply topology. First, fault tolerance of the drive is improved, since the supply is realised with two independent inverters. In case one of the inverters is faulted, the other can continue to provide power to the machine. Second, the same phase voltages can be achieved with half the dc-link voltages on the two inverter inputs compared to the single-sided supply, which can be useful in applications such as electric and hybrid electric vehicles and medium sized ships, where the dc voltage levels are limited. Further, due to the nature of the topology, additional diodes and capacitors like in the Neutral Point Clamped (NPC) and Flying Capacitor (FC) VSIs are not required. The latter results in a further advantage - capacitor voltage balancing techniques are not required. Two pulse width modulation (PWM) techniques for control of the dual-inverter supplied six-phase drives are proposed in this thesis. The first is a reference sharing algorithm where the inverters are modulated using reference voltage that is shared equally and unequally between the two modulators. For both symmetrical and asymmetrical six-phase drives, a better performance, in term of total harmonic distortion (THD) of phase voltage is obtained when the reference is shared unequally between the two modulators. The second technique is carrier-based modulation where the modulation of the two inverters is determined by the disposition of the carrier signals. Three variations of carrier signals disposition are investigated namely; the phase disposition (PD-PWM), alternate phase opposition disposition (APOD-PWM) and phase-shifted PWM (PS-PWM). For the symmetrical six-phase drive, the best phase voltage and current THDs are obtained using APOD-PWM while for asymmetrical six-phase drive, the APOD-PWM produces the worst current THD despite having the best voltage THD among the three methods. All the developed modulation techniques are analysed using simulations and experiments undertaken using a laboratory prototypes. The waveforms and spectra of phase voltage and load current obtained from the simulation and experimental works are presented in this thesis together with the THD of both the voltage and current over entire linear modulation range.

Abstract:
Master of Science<br>Department of Electrical and Computer Engineering<br>Behrooz Mirafzal<br>In this thesis, a modified version of the phasor pulse width modulation (PPWM) switching method for use in a single-stage three-phase boost inverter is presented. Because of the required narrow pulses in the PPWM method and limitations in controller resolution, e.g. dSPACE, the desired switching pattern for a boost inverter requires a costly processor. A low resolution processor can cause pulse dropping which results in some asymmetric conditions in output waveforms of the boost inverter and therefore, an increase in the THD of the output waveform. In order to solve this problem, a new switching pattern is developed which guarantees symmetric conditions in the switching pattern by discretizing the switching pattern in every switching cycle. This switching pattern has been applied to a boost inverter model developed by SimPowerSystems toolbox of MATLAB/Simulink. The model has been simulated in a wide range of input DC voltage and load. Moreover, a laboratory-scaled three-phase boost inverter has been designed, built, and tested using an identical switching pattern in the same input voltage and load range. Both simulation and experimental results confirm the effectiveness of the new switching pattern.

A principal vantagem do NSI é o menor número de chaves (nove em vez de doze do conversor back-to-back), que, como consequência, acarreta em restrições nas amplitudes de saída do inversor. Na literatura, foram propostas diferentes técnicas de modulação por largura de pulso (Pulse Width Modulation - PWM) que respeitam estas restrições. Diante deste cenário, o presente trabalho propõe duas abordagens para a generalização da modulação no NSI: a modulação escalar quasi generalizada e a generalizada, que são baseadas no conceito de generalização para o inversor trifásico fonte de tensão (VSI) convencional e que podem ser facilmente implementadas com um reduzido esforço computacional. Este conceito propicia, através de uma abordagem sistemática e direta, a geração de qualquer técnica de PWM, seja ela contínua ou descontínua, através do ajuste de graus de liberdade específicos. Objetivando a redução de perdas, são apresentados os graus de liberdade específicos que, quando aplicados nas modulações propostas, aumentam o rendimento do inversor. Resultados de simulação confirmam a funcionalidade das modulações.<br>The nine-switch inverter (NSI) has been proposed recently and, since then, a large number of applications were explored for this new topology, specially as a possible substitute to the traditional back-to-back converter. The main advantage of the NSI is its lesser number of switches (nine instead of twelve of the back-to-back converter), which, as a consequence, leads to some restrictions in the total attainable amplitude at its outputs. In literature, many pulse width modulation (PWM) techniques were proposed respecting those restrictions. In this scenario, this paper proposes two generalization approaches for the modulation of the NSI: the quasi generalized scalar modulation and the generalized scalar modulation, which are based on the generalization concept for the voltage source inverter (VSI), easily implemented with a reduced computational effort. Such concept leads to a systematic and straight approach to the generation of any continuous or discontinuous PWM technique for the NSI, simply adjusting a few degrees of freedom of the modulation strategy. Aiming the reduction of the power losses, specific degrees of freedom are presented, for the proposed modulations. Simulation results confirm the validity of the proposed methods.

Abstract:
Multilevel inverters have attracted wide interest in both the academic community and the industry for the past decades. Therefore, the investigation and development of modulation strategies in multilevel inverters emerges as a necessity for the industry and researchers. In this doctoral thesis, alternative modulation methods suitable for three-level conventional single-phase inverters and especially for cascade H-bridge multilevel inverters are discussed and proposed. The theory of Equal Areas is reformed and presented and its modifications are proposed. These modifications are compared with other well-known modulation schemes, such as carrier-based modulation schemes and programmed pulse width modulation techniques. The advantage of the modified Equal Areas Pulse Width Modulation (EAPWM) is its algorithmic simplicity due to simple algebraic relationships, which results in less computational effort. A fully mathematical formulation for the Equal Areas modulation is proposed for both conventional and multilevel inverters. The EAPWM is shown to produce well-formed switched output voltages that have low total harmonic distortion at even low switching frequencies. The importance of this thesis is complimented by the results, produced after the implementation of EAPWM in multilevel inverters, which can be used as a more accurate reference when compared with other modulation strategies. Moreover, this direct modulation strategy has been extended to work on higher amplitude modulation ratios, in a linear manner, while entering the over modulation region. In this context, modified algorithms have been developed using different criteria for the calculation of the pulses’ width and their placement inside the time interval. The equal areas method, implemented in conventional single-phase inverters, uses odd pulse numbers per half cycle, holding integer frequency ratios in contrast to its implementation in multilevel inverters, where non-integer frequency ratios occur due to the level-by-level application. The application of the method is verified by simulations together with experimental work using a full-scale prototype inverter.
