    开关电源

    开关电源是什么?

    开关电源,又称SMPS(Switch-mode Power Supply),是一种用于转换电源的电子电路。

    开关电源的工作原理

    • 开关电源的功能是将一个位准的电压,透过不同形式的架构转换为用户端所需求的电压或电流。
    • 开关电源的输入多半是交流电源(例如市电)或是直流电源,而输出多半是需要直流电源的设备,例如个人电脑,而开关电源就进行两者之间电压及电流的转换。
    • 开关电源内容纳了复杂的电容器,通过稳定的电压输出,可以保证主板、CPU、内存、硬盘能够获得稳定的直流电压。
    • 开关电源在能耗上等级越高,越节能,同时也意味着发热量低,从而可以很好地稳定工作,并让输出点的需求方获得更佳性能。

    开关电源的应用

    我们生活中使用的台式机电源就是常见的开关电源。其他常见的应用有:

    • 工业自动化控制
    • 军工设备
    • 科研设备
    • LED照明
    • 工控设备
