Abstract :
Nowadays there is an increasing attention towards multiphase drives, especially for medium and high power applications. In this paper some modulation strategies for M-phase inverters are compared and the modulation strategy with the minimum switching losses is determined. If the switching devices of the inverter are IGBTs or BJTs, this modulation strategy turns out to be the one with the minimum total power losses. Simulation and experimental results confirm the validity of the analytical approach and the feasibility of the proposed modulation strategy.
