Abstract

This paper introduces an auxiliary motor drive solution based on three-phase onboard battery charger to improve drive capability. The specific scheme of the control strategy is given by circuit analysis and modeling. The proposed scheme reduces the current stress on the driving inverter, increases the total converter output current, achieves fault tolerance, and improves the dynamic response performance based on mathematical model analysis. Besides, the improvements need few additional components, so that the cost is quite low. The above functions have been verified by experiments or simulations.

基于三相车载电池充电器的辅助电机驱动
本文介绍了一种基于三相车载电池充电器的辅助电机驱动方案,以提高驱动性能。通过电路分析和建模,给出了控制策略的具体方案。该方案在数学模型分析的基础上,减小了驱动逆变器的电流应力,增加了变流器的总输出电流,实现了容错,提高了动态响应性能。此外,改进需要的额外组件很少,因此成本很低。上述功能均已通过实验或仿真验证。
