Abstract:
This paper deals the implementation of 3-level output voltage using dual 2-level inverter with control of sub-region based Space Vector Modulation (SR-SVM). Switching loss and voltage stress are the most important issues in multilevel inverters, for keep away from these problems dual inverter system executed. Using this proposed system, the conventional 3-level inverter voltage vectors and switching vectors can be located. In neutral point clamped multilevel inverter, it carries more load current fluctuations due to the DC link capacitors and it requires large capacitors. Based on the sub-region SVM used to control IGBT switches placed in the dual inverter system. The proposed system improves the output voltage with reduced harmonic content with improved dc voltage utilisation. The simulation and hardware results are verified using matlab/simulink and dsPIC microcontroller.

Abstract:
Over the past decade, research efforts have been made to decrease the number of power electronic devices needed in multi-motor drive systems in order to condense the overall complication and cost of the drive. This paper proposes speed control for a dual three-phase induction motor system driven by five-leg voltage source inverter (FL-VSI) which is used in industrial manufacturing processes. Industrial applications frequently need a number of variable speed electric drives. This technique uses five-leg inverter instead of using conventional two three phase inverters. In the majority of cases, these multi-motor drive systems need independent control of individual motors. It is shown recently that it is possible to separately control two three-phase induction machines supplied through a five-leg voltage source inverter, with one inverter leg being common to both machines. The entire performance of the speed control for the five leg voltage source inverter fed dual-motor drive system is investigated using MATLAB/SIMULINK software.

Abstract:
<p>Nowadays, A lot of industry requires Multi Motor System (MMS)<strong> </strong>applications such as propulsion and traction power, HEV, conveyer and air-conditioner. The Conventional arrangement for MMS usually done by cascading the motors drives which each drives has individual inverter. Part of MMS, Dual-Motor drives fed by a single inverter is being paid attention by the researchers. Dual-motor drives using a single three-leg inverter<strong> </strong>has its limitation in the case of different operating conditions and independent speed control requirement. Therefore, dual-Motor drives using a single Five-leg Inverter (FLI) was proposed for independent control for both motors. In PMSM drives, the information of the feedback speed and rotor angular position is compulsory for variable speed drives. Conventional solution is by using speed sensor which will increase size, cost, extra hardwire and feedback devices, especially for the case of dual-PMSM drives. The best solution to overcome this problem is by eliminating the usage of speed and position sensors for Dual-motor drives. This paper presents a new sensorless strategy using speed and position estimator for Independent Dual- Permanent Magnet Synchronous Machine (PMSM) drives which utilize Five-Leg Inverter (FLI). The proposed strategy is simulated using MATLAB/Simulink to evaluate the overall motor drive performance. Meanwhile the experimental set-up is connected to dSPACE 1103 Board. The experimental results demonstrate that the proposed estimator is successfully managed to control the Dual-PMSM drives for variation of speed and for different direction applications.</p>

Abstract:
<span>Power quality issues are the most concerned area for electrical engineers in these modern days due to indusrtrialization and advancements in electronics. Harmonics are one of the power quality issues that deteriorated the quality of source components delivered to load. Active power filters (APF) are the compensating devices used to mitigate harmonics. Distributed generation (DG) became a trendline due to economical, technical and environmental reasons. This paper presents the harmonic compensation using dual APF sharing compensating signals while active power is fed from distributed generation to grid. DG inverter acts as an interface between DG system and grid to feed active power from DG to grid. In this context, the DG inverter acts both as inverter and APF, used as inverter to invert supply from DG and feeds grid for specified time and also as APF for harmonic compensation thereafter along with dual APF. The proposed system is developed and results are obtained using MATLAB/SIMULINK software. Results are shown for DG inverter feeding active power to grid and also acting as APF. Dual APF characteristics are also shown. </span>

Abstract:
<span>The objective of this article is to analyze the performances of Non-Independent Speed Control of Dual-PMSM (Permanent Magnet Synchronize Motor) Drives by a single Three-Leg Voltage Source Inverter (VSI) using control of Mean and Differential Torque technique. In general, there are two types of control strategies for Dual-Motor drives. One is Master-Slave technique and another one is Mean Control technique. For mean control technique, this study chooses mean and differential approach for the motors parameters and averaging the voltage space vector. The advantages of Dual-Motor drives fed by a single inverter topology are, it can reduce size and cost compared to the Dual-motor drives fed by individual inverter, either in industrial or in traction applications. However, by using a single three-phase inverter, the topology only restricted for the same operating conditions which are at the same speed, same parameters and same direction. The dual-motors are dependent (non-independent) on the other motor. It is can only be tested on different load operation. The analysis is focuses on speed and load variation for Dual-PMSM drives considering the forward and reverse operations of the motor. This simulation model is modelled using MATLAB-Simulink.</span>

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:
L'oggetto della tesi consiste nella progettazione e realizzazione di un azionamento Dual Inverter a singola alimentazione per il controllo di macchine elettriche sincrone a pura riluttanza con centro stella aperto. La configurazione dell'azionamento prevede l’utilizzo di un solo pacco batteria collegato al primo inverter, mentre il secondo è direttamente alimentato da un condensatore flottante posizionato sul rispettivo bus DC; in altre parole, tale struttura può essere vista come un sistema alimentato da un singolo inverter con l’aggiunta di un compensatore della potenza reattiva di macchina. La configurazione studiata possiede le potenzialità per essere utilizzata sia in ambito automotive, che in applicazioni industriali. Tale sistema, oltre a migliorare lo sfruttamento del convertitore principale facendolo lavorare a fattore di potenza unitario, accresce il limite di tensione disponibile ai capi degli avvolgimenti della macchina a parità di tensione del pacco batterie e amplia la regione a coppia e a potenza costante, ritardando i deflussaggi per ottenere maggior coppia elettromagnetica ad elevate velocità. L'elaborato realizzato prevede una caratterizzazione sperimentale della macchina elettrica utilizzata, allo scopo di realizzare un sistema di controllo ottimizzato e una comparazione analitica tra l’azionamento dotato di singolo inverter e quello dotato di compensatore della potenza reattiva, per la verifica delle basi teoriche presenti in letteratura. Tutto ciò è stato poi confermato attraverso simulazioni in ambiente Simulink e prove sperimentali eseguite mediante sistema di prototipazione rapida dSPACE. L'azionamento è stato collaudato, testato e risulta essere funzionante per ogni valore del rapporto di tensione dei bus DC; dalle varie fasi del progetto sono stati ricavati risultati omogenei e concordi, che certificano l'efficienza del sistema e confermano la validità dei vantaggi dedotti dallo studio preliminare.

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:
Renewable energy and distributed generation are getting more and more popular, including photovoltaic modules (PV), wind turbines, and fuel cells. The renewable energy sources need the power electronics interface to the utility grid because of different characteristics between the sources and the grid. No matter what renewable energy source is utilized, inverters are essential in the microgrid system. Thanks to flexible modular design, transformerless connection, extended voltage and power output, less maintenance and higher fault tolerance, the cascade inverters are good candidates for utility interface of various renewable energy sources. This dissertation proposes a new type of cascade inverters based on dual-buck topology and phase-shift control scheme. Compared to traditional cascade inverters, they have enhanced system reliability thanks to no shoot-through problems and lower switching loss with the help of using power MOSFETs. With phase-shift control, it theoretically eliminates the inherent current zero-crossing distortion of the single-unit dual-buck type inverter. In addition, phase-shift control can greatly reduce the ripple current or cut down the size of passive components by increasing the equivalent switching frequency. An asymmetrical half-cycle unipolar (AHCU) PWM technique is proposed for dual-buck full-bridge inverter. The proposed approach is to cut down the switching loss of power MOSFETs by half. At the same time, this AHCU PWM leads to current ripple reduction, and thus reducing ripple-related loss in filter components. Therefore, the proposed PWM strategy results in significant efficiency improvement. Additionally, the AHCU PWM also compensates for the zero-crossing distortion problem of dual-buck full-bridge inverter. Several PWM techniques are analyzed and compared, including bipolar PWM, unipolar PWM and phase-shifted PWM, when applied to the proposed cascade dual-buck full-bridge inverter. It has been found out that a PWM combination technique with the use of two out of the three PWMs leads to better performance in terms of less output current ripple and harmonics, no zero-crossing distortion, and higher efficiency. A grid-tie control system is proposed for cascade dual-buck inverter with both active and reactive power flow capability in a wide range under two types of renewable energy and distributed generation sources. Fuel cell power conditioning system (PCS) is Type I system with active power command generated by balance of plant (BOP) of each unit; and photovoltaic or wind PCS is Type II system with active power harvested by each front-end unit through maximum power point tracking (MPPT). Reactive power command is generated by distributed generation (DG) control site for both systems. Selective harmonic proportional resonant (PR) controller and admittance compensation controller are first introduced to cascade inverter grid-tie control to achieve better steady-state and dynamic performances.

Toutefois, du fait du dispositif optique, un positionnement mécanique très précis du générateur CPV via un traqueur solaire à deux axes de rotation est nécessaire. La première partie du travail de thèse consista à développer un onduleur hybride ou « Tracking Inverter » capable d’injecter le courant produit par un traqueur CPV tout en réalisant son positionnement.

Abstract:
A single-phase grid connected transformerless photovoltaic (PV) inverter for residential application is presented. The inverter is derived from a boost cascaded with buck converter along with a line frequency unfolding circuit. Due to its novel operating modes, high efficiency can be achieved because there is only one switch operating at high frequency at a time, and the converter allows the use of power MOSFET and ultra-fast reverse recovery diode. This dissertation begins with theoretical analysis and modeling of this boost-buck converter based inverter. And the model indicates small boost inductance will leads to increase the resonant pole frequency and decrease the peak of Q, which help the system be controlled easier and more stable. Thus, interleaved multiple phases structure is proposed to have small equivalent inductance, meanwhile the ripple can be decreased, and the inductor size can be reduced as well. A two-phase interleaved inverter is then designed accordingly. The double-carrier modulation method is proposed based on the inverterâ s operation mode. The duty cycle for buck switch is always one if the inverter is running in boost mode. And the duty cycle for boost switches are always zero if the inverter is running in buck mode. Because of this, the carrier for boost mode is stacked on the top of the carrier for buck mode, as a result, there is no need to compare the input and output voltage to decide which mode the inverter should operate in. And the inverter operates smoothly between these two modes. Based on similar concept, three advanced modulation methods are proposed. One of them can help further improve the efficiency, and one of them can help increase the bandwidth and gain, and the last one takes the advantage of both. Based on similar concept, another three dual-mode double-carrier based SPWM inverters are proposed. With both step-up and step-down functions, this type of inverter can achieve high efficiency in a wide range because only one switch operates at the PWM frequency at a time. Finally, the simulation and experiment results are shown to verify the concept and the tested CEC (California Energy Commission) efficiency is 97.4%. It performs up to 2% more efficiently better than the conventional solution.

Abstract:
Il lavoro di tesi riguarda un azionamento elettrico denominato Dual Inverter. Questo è costituito da una macchina elettrica a centro stella aperto controllata tramite l'utilizzo di due inverter collegati alle due estremità degli avvolgimenti statorici. L'inverter principale collega la macchina all'alimentazione, che in ambito automotive potrebbe essere un pacco batterie, mentre l'inverter secondario ha il bus DC collegato a un banco flottante di condensatori, nella configurazione di un filtro attivo. Il vantaggio principale di questo azionamento è quello di aumentare la tensione ai capi degli avvolgimenti di macchina a parità di tensione di alimentazione, con un conseguente ampliamento delle regioni a coppia e a potenza costante, in termini di velocità. L'obbiettivo dell'elaborato è l'implementazione di un innovativo sistema di controllo che permetta: il funzionamento dell'inverter principale in regime di modulazione ad onda quadra, sfruttando la possibilità di compensare le armoniche indesiderate che tale regime introduce grazie alla presenza del secondo inverter; la regolazione della tensione del condensatore flottante in base alle condizioni di funzionamento e alla tensione richiesta all'inverter secondario. Lo studio comprende la verifica delle basi teoriche presenti in letteratura relative al sistema in analisi, la definizione di un modello matematico completo, l'implementazione del nuovo sistema di controllo, una serie di simulazioni numeriche eseguite in ambiente Simulink e delle prove sperimentali realizzate sul sistema reale, mediante un sistema di prototipazione rapida denominato dSPACE, presente nel laboratorio LEMAD del Dipartimento di Ingegneria dell'Energia Elettrica e dell'Informazione dell'Università di Bologna.

Dopo una descrizione della struttura e la spiegazione del principio di funzionamento di una macchina brushless trifase, vengono esposte le equazioni relative al modello matematico ai valori istantanei della macchina, per confrontarle in seguito con il caso multifase, e viene introdotto il concetto di regolazione della velocità e regioni di funzionamento della macchina. Vengono, poi, descritte altre possibili configurazioni dell’azionamento, oltre a quella presa in esame in questo lavoro di tesi, e ricavate le equazioni del modello matematico dell’azionamento. Di seguito sono descritte la configurazione di un inverter trifase e le varie tensioni di uscita che è in grado di fornire, e sono esposti i limiti di corrente e di tensione della macchina e dei due inverter presenti in questo azionamento; viene descritta la condizione di ottimo funzionamento e, infine, sono rappresentate le curve dei limiti di corrente e tensione, le regioni di funzionamento al variare della velocità e analizzati i vantaggi di questo azionamento rispetto a quello con singolo inverter. Successivamente viene descritto lo schema di controllo completo dell’azionamento e analizzati nel dettaglio i suoi componenti. Vengono spiegati, inoltre, i blocchi di Simulink utilizzati per costruire questa nuova tecnica di controllo per questo azionamento; in particolare viene preso in considerazione il modello relativo allo schema di controllo della velocità, quello del sistema Dual Inverter, quello della macchina brushless e quello del carico meccanico. Infine vengono analizzati i grafici relativi alle simulazioni fatte e presi in considerazione i vantaggi ottenuti rispetto ad un azionamento con singolo inverter.

Nella tesi sono stati studiati e analizzati due azionamenti elettrici basati su macchina asincrona per applicazioni di trazione elettrica. Gli obiettivi principali consistono nell'ampliare la regione di funzionamento a coppia costante e aumentare, quanto più possibile, la coppia elettromagnetica prodotta dalla macchina nelle regioni di deflussaggio, ad alta velocità. Il primo capitolo è dedicato allo studio della macchina asincrona alimentata da un inverter e all'analisi delle prestazioni limite. Nel secondo capitolo si è analizzata una configurazione dual inverter, dove due convertitori sono collegati alle estremità opposte dell'avvolgimento trifase di statore: il convertitore principale è alimentato da un pacco batterie, mentre il convertitore secondario è alimentato da un condensatore flottante e costituisce un filtro attivo in grado di compensare la potenza reattiva assorbita dalla macchina, garantendo un fattore di potenza unitario sull'inverter principale. Il terzo capitolo è dedicato allo sviluppo di una nuova configurazione dual inverter nella quale il secondo convertitore è alimentato da un condensatore flottante ed è posto in parallelo al primo.
