Abstract
The multi-phase inverter modulation and control method is a hotspot of multiphase systems. There is no general space vector modulation available due to the inherent difficulty in synthesizing more than one independent space vector simultaneously in different d-p planes. This paper established the distribution model of five-phase inverter space vector from a novel perspective of magnetic motive force (MMF) equivalence. And then a multi-dimensional SVPMW method applicable to the non-sinusoidal voltage output was proposed based on the obtained space vector distribution laws. The proposed multi-dimensional SVPWM method effectively improves the fundamental modulation range and is suitable for five-phase inverter non-sinusoidal modulation.
