混合动力电动汽车高频交流控制系统

A high frequency AC control system for hybrid electric vehicle

根据混合型电动汽车的性能要求 ,提出了一种采用高频交流的混合动力控制系统。系统采用间接矢量控制技术 ,通过高频交流脉冲密度调制接口变换器 ,对功率进行协调控制。理论分析和计算机仿真结果表明 ,这种新型的高频交流混合动力控制系统响应快 ,具有良好的动态性能。

According to driving requirements of hybrid electric vehicle(HEV),a novel high frequency AC hybrid power control system is presented.The suggested system makes use of a single phase HFAC pulse density modulation(PDM) converter as the interface to connect energy storage unit and power source for induction motor drive system.The system uses vector control theory to co operate the gasoline engine generator set and battery inverter set by means of soft switching pulse density modulation(PDM) converters. Theory analysis and simulation results demonstrate that the proposed HFAC hybrid powers system has merits of fast system response,good dynamic performance.
