Keywords: Six-phase inverter, single neutral, multiple d-q planes, even phase number, space vector modulation
AbstractA novel space vector pulse width modulation (PWM) scheme based on the employment of medium magnitude space vectors for six-phase voltage source inverter has been developed. The proposed PWM scheme allows generating the six-phase voltage with the reduced level of low order harmonics. It is suitable for inverters driving six-phase AC induction motors with sinusoidal distribution of windings, with a single neutral point.
