Abstract :
Pole-phase modulation adjusts the pole-phase ratio of an induction machine and requires a multileg, multiphase inverter. This paper analyzes an n-leg n-phase inverter and presents techniques for n-phase space vector pulse width modulation (SVPWM). In particular, nine-phase SVPWM is developed and implemented on a nine-winding induction machine. The nine-phase SVPWM is compared to nine-phase sine-triangle PWM in terms of dc bus utilization.
