Proposal to increase the convertible power by an hybrid excitation flux switching synchronous machine associated with an voltage inverter. Application in hybrid or electric vehicle

Abstract

Synchronous machines associated with their voltage inverter are generally controlled in current mode. In this paper, we are interested in supplying in full-wave voltage. The second part describes the expected performance with this control mode. In the third part, we present a hybrid excitation flux switching synchronous machine (HEFSSM) whose characteristics make it a potential candidate for electric motors of hybrid or electric vehicles. The experimental results of this HEFSSM containing ferrite permanent magnets (Br=0,4T) fed in full-wave voltage to convert the maximal power are presented in the fourth part. In the last section, we present two solutions to increase the maximal convertible power, so the maximal speed in no-load mode.
