Novel Space Vector Pulse Width Modulation Technique for 5-Phase Voltage Source Inverter

This paper presents the development of three different SVPWM methods for a five-phase voltage source inverter (VSI) in matlab/simulink. Five-phase voltage source inverters are dominantly used to supply the five-phase drives which are used for high power applications. It is necessary to develop appropriate space vectors for the inverters to provide required output voltages to a five phase machine. In the SVPWM technique a large, medium and combinations of large and medium space vectors are detailed. The performances of the inverter with 5-phase are analyzed with these switching techniques. The output voltage, THD and lower order harmonics are observed through simulation. The performances of the inverter with the above switching vectors are compared for different modulation indices and the results are presented.
