Abstract

A novel propulsion system scheme using a soft-switched high frequency AC-AC converter for an electric vehicle is proposed in this paper. The system consists of three parts: high frequency inverter, high frequency transformer and soft-switched high frequency AC-AC converter. The DC voltage of battery firstly is inverted into 20 kHz high frequency AC voltage, which is boosted and isolated by transformer, and then the output voltage of the transformer is served as voltage source to feed the AC-AC converter for driving the motor. Owing to using zero voltage switching technique, the propulsion system has advantages of high efficiency, high energy density, small volume and light weight.

一种采用软开关高频交-交变换器的电动汽车推进系统新方案

提出了一种采用软开关高频交-交变换器的新型电动汽车推进系统方案。该系统由三部分组成:高频逆变器、高频变压器和软开关高频交流变换器。首先将蓄电池的直流电压倒转为20khz的高频交流电压，经变压器升压隔离后，变压器的输出电压作为电压源馈入交-交变换器驱动电机。由于采用了零电压开关技术，推进系统具有效率高、能量密度高、体积小、重量轻等优点。
