2015 (English)In: 2015 IEEE INTERNATIONAL ELECTRIC MACHINES & DRIVES CONFERENCE (IEMDC), Institute of Electrical and Electronics Engineers (IEEE), 2015, 941-945 p.Conference paper (Refereed)
Multiphase machine drive systems have been applied in many electric propulsion fields such as aerospace and electric vehicle applications. With the development of SiC semiconductors, its superior characteristic makes compact multiphase converters possible. Moreover, by using a single chip in each switch, problems caused by an uneven current split between paralleled devices can be avoided. This paper presents a performance evaluation for a 50 kW multiphase EV/HEV drive system with 1.2 kV SiC MOSFETs. Power loss calculation, cost comparison and system simulation are provided to illustrate the feasibility of the proposed concept.
