摘要
目前轨道交通车辆普遍采用的低压直流电源供电制式为110V和24V,其中110V直流电源集成在车载辅助供电系统中,通过辅助供电系统将接触网上高压电变换为满足轨道交通车辆运营需求的110V直流电,而24V直流电需采用额外的电能变换模块来获取。针对轨道交通车辆24V直流电源的设计,介绍了一种基于ZVS软开关技术的节能控制方案,并进行了仿真研究,结果表明遵循该节能方案的24V直流电源同样取得了较好的动静态特性。
So far, low-voltage DC power has been widely used in rail transit vehicles, including 110V and 24V. 110V DC power is integrated in the vehicle auxiliary power supply system, through which it contacts high voltage electricity fi＇om the grid, transformed into a satisfied kind of 110V DC power. While 24V DC power is got by additional electric energy. As for the design of 24V DC power of rail transit vehicles, an energy-saving control scheme based on ZVS soft switching technology is introduced, a simulation research also being done. The rcsult shows that such a 24 DC power has a good static and dynamic performance as well.
