双源无轨电车电机驱动系统主电路改进设计

Improvement Design on Main Circuit of Motor Drive System for Dual-source Trolley Buses

为解决传统双源型无轨电车电机驱动系统电制动再生能量只能进行斩波消耗处理影响节能效率,同时整车必须额外配置车载高压充电设备对车载电池进行充电而增加整车制造成本的问题,通过对其主电路硬件及软件控制策略进行改进设计,实现了对电制动再生能量的回收利用及替代车载高压充电设备的功能,既有效降低了能耗,又减少了整车电气系统的规模,从而提高了系统的可靠性。

To solve the problems that energy-saving efficiency is influenced because the electrical braking renewable energy of the motor driving system for the traditional dual-source trolley buses can only be processed by way of the chopped consumption, and the vehicle manufacturing cost is increased since the on-board high-voltage battery charger has to be allocated additionally to charge the on-board batteries in the vehicle, the authors improve the design of the main circuit hardware and software control strategy, and implement the recycling utilization of the electrical braking regenerative energy and the function of replacing the on-board high voltage charging equipment in the vehicle, which effectively reduce the energy consumption and the scale of the vehicle electrical system, so as to enhance the system reliability.
