Loss Minimization of a PMSM Drive for a Hybrid Electric Vehicle

Paper i proceeding, 2004

This paper considers minimization, by means of control, of losses in permanent-magnet synchronous motor (PMSM) drives in hybrid-electric vehicle (HEV) applications. A case study is presented to investigate the impact of loss minimization for an experimental PMSM drive, developed for propulsion in a series HEV. The case study shows that the additional inverter losses, due to the extra field weakening added, reduce the potential to minimize losses considerably.
