Research on High Power Density Inverter for EV Drive
For any electric vehicle (EV), whether pure, hybrid or fuel cell, the requirements for its electric drive train can be summarized as high power density, high power efficiency, high reliability and low cost etc. In order to meet these requirements, permanent magnet motor and high power density inverter are used. In this presentation, electric vehicle R&D activities, especially EV drive, in China since 1996 are summarized. The development of a high power density inverter for EV drive is presented. This research focuses on the inverter performance and capacitor behavior analysis during EV operation, as well as capacitor bank design. The experiments show that the inverter with two 220uF film capacitor can drive 80kW PM motor with power density of 13.3kW/l and maximum system efficiency of 92％.
