Abstract :
Different continuous PWM strategies of multi-phase inverter-fed AC motors are investigated from point of view of AC motor harmonic losses. It is shown that for phase number over seven the natural or regular sinusoidal PWM of multi-phase system gives the best solution both from the point of view of the simplicity of realization and the value of harmonic losses. However, these losses are slightly higher than those in case of three-phase system. The theoretical results are checked by simulation.
