摘　　要：采用前馈控制的方式,可以提高带蓄电池负载的DC/DC变换器的动态性能。针对列车上采用的半桥式DC/DC电源装置设计了与其相适应的前馈控制器,并且对该系统进行了仿真。仿真分析表明,这种前馈控制方式能够大大改善系统的动态性能以及稳定精度。Dynamic performance of DC/DC converter with battery load could be enhanced by adopting feed-forward control method. Feed-forward controller for vehicle supply based on half-bridge topological DC/DC converter was designed and simulated, which was proved to greatly enhance the dynamic and stability performance of the system.
