Six-phase voltage forming method using the largest magnitude space vectors

Abstract

In this paper, a six - phase voltage source inverter with a single - neutral star connected load is investigated. A space vector PWM (SVPWM), which uses largest magnitude vectors is proposed and implemented. Simulation results of the six - phase voltage source inverter (VSI), which uses the proposed SVPWM method, are compared to the results when a standard sinusoidal PWM scheme is used. Analysis of the results shows that proposed SV PWM scheme is suitable to form a six - phase sinusoidal output voltage. The main advantage of proposed SVPWM scheme is that it requires the same computational resources as the three - phase SVPWM
