辅助设备启动或者电池充电器电压波动过程均会影响蓄电池的输出电压。

在蓄电池的电压波动过程中，车辆控制电子设备不应该引起功能的改变。

为了解决车辆控制设备的行业应用问题，满足电压波动和其他特性需求，需要宽电压范围输入电源产品满足需求。

金升阳铁路电源系列如下：图1.金升阳DC/DC铁路电源结构金升阳铁路电源EMC专业滤波器系列如下：图2.铁路电源EMC滤波器1.2铁路电源标准铁路上的车辆控制电子设备和器件，在国际上有着严格的规定和管控。

在欧洲，最常用的是EN50155：2007标准--“铁路设施铁道车辆的电子设备”标准，中国最常用的是铁标TB/T3021：2001，而英国常用的标准为RIA12用于拖动及运载设备的直流控制系统中瞬态浪涌保护的通用规范”此规范是由铁路工业联会开发制定的。

欧盟标准EN50155与中国铁标TB/T3021要求基本一致，而RIA12标准则要求车载电子设备具有专门的抗浪涌能力。

欧盟标准EN50155已慢慢被许多铁路设备生产制造商认可，标准适合于安装在铁道车辆用作控制、调整、保护、供电的的全部电子设备，并涉及到蓄电池供电系统和直接与接触系统连接或者未连接的低压电源，但是不适合主电路设备。

电源模块作为总线电源转换器件，前端供电主要由车载蓄电池供电或者辅助电源供电。
