摘　　要：铁路客车的重要组成部分之一铁路客车的供电系统,为客车上各部分的电器设备提供电源,当前,铁路客车的供电来源于机车受电弓从接触网接受到25KV单相交流电,经过降压、整流、滤波等步骤处理,电路拓扑结构复杂。本文设计一款集中式开关电源的拓扑结构,以期实现功能并提升效率。As an important component of railway passenger cars,the power supply system of railway passenger cars is a system equipment that provides power for various electrical equipment on the passenger cars.Currently,the power supply of railway passenger cars comes from the locomotive pantograph receiving 25KV single-phase AC power from the contact network,which is processed through steps such as voltage reduction,rectification,and filtering.The circuit topology structure is complex.This article designs a topology structure of a centralized switching power supply to achieve functionality and improve efficiency.
