电源模块的工作过程很特殊，工作时序和电压提升分3段，阶段1是380V交流电整流达到400VDC，阶段2是检测到400VDC后，继续使DC-LINK电容充电到570VDC，阶段3是等待脉冲使能信号出现，提升DC-LINK电压到600VDC。由于同时提供启动、驱动使能、脉冲使能信号，上述三步间隔时间极短，IGBT整流桥在使能条件刚满足就开始工作。

当IGBT整流桥和脉冲分配电路由于电压不稳定、湿度、粉尘积聚等原因而发生大电流击穿或脉冲顺序失调时，浪涌电流通过直流母线冲击坐标轴功率模块的IGBT直流侧，这是电源模块短路燃烧的根本原因。IGBT整流桥短路时，输入电抗器应起到一定的防止电流过快上升的作用，绝缘容量的降低导致电感急剧下降，不能有效发挥保护作用，这也是功率模块燃烧的次要原因。

中国的正常电压范围为380(1≤15%)V≤380(1≤10%)V。西门子电源模块的电压要求为380±5V交流电，当电源超过西门子要求时，电源模块的自保护功能(熔断器)就会丧失，保险丝和相关的三个电气元件将同时被击穿，导致电源模块的烧毁。

电源模块是可直接安装在印刷电路板(PCB)上的电源。它可以为专用集成电路(ASIC)、数字信号处理器(DSP)、微处理器、存储器、现场可编程门阵列(FPGA)和其他数字或模拟负载提供电源。一般来说，这种模块被称为负载点(POL)电源系统或使用点电源系统(PUPS)。由于模块化结构的诸多优点，模块化电源广泛应用于交换设备、接入设备、移动通信、微波通信、光传输、路由器等通信领域、汽车电子、航空航天等领域。

如何解决电源模块输出电压过低问题？

当电源模块输出电压过低时该怎么解决呢？输出电压过高过低都不好，上一篇文章我们说到了输出电压过高的解决方法，今天我们来讲讲输出电压过低要怎么解决。输出电压过低会导致什么问题呢？可能会导致整体系统不能正常工作，就拿我们生活中常见的例子来说好了，电压过低时，灯泡都不亮或者暗下来了，这肯定是满足不了我们的需求的。如果长期处于电压过低情况，那么会使电路寿命大大折损，那么面对这个问题我们该如何解决呢？
