Abstract :
This paper presents an improved PWM control of six-phase voltage source inverters supplying a split-phase induction motors. The approach is based on a space vector modulation and designed to improve the performance of the system in terms of THD and DC bus utilization. Several scalar and vectorial patterns are proposed and evaluated by using the total harmonic distortion as a figure of merit. Simulation and experimental results are presented to demonstrate the feasibility of the proposed solutions.
