Generating the Output Voltages in the 5-phase Voltage Source Inverters 

Abstract

In the five-phase Voltage-Source Inverters, the activation of transistors results in simultaneous generation of two, interrelated

output voltage vectors. Control strategies for 5-phase induction motors require both voltage vectors generated in the inverter to have strictly

specified lengths and positions. Independent generation of two voltage vectors with the parameters determined in the induction motor

control system can be done by appropriate Pulse Width Modulation (PWM) strategy. This paper presents two methods of Space-Vector PWM

for five-phase inverters. Both solutions allow independent generation of both voltage harmonics with a higher priority of the first voltage

harmonic.
