开关型直流稳压电源

与线性稳压电源不同的一类稳电源就是开关型直流稳压电源，它的电路型式主要有单端反激式，单端正激式、半桥式、推挽式和全桥式。它和线性电源的根本区别在于它变压器不工作在工频而是工作在几十千赫兹到几兆赫兹。功能管不是工作在饱和就是截止区即开关状态；开关电源因此而得名。

泵类负载采用变频调速后，节电率为20%～60%，这是因为风机、泵类负载的实际消耗功率基本与转速的三次方成比例。当用户需要的平均流量较小时，风机、泵类采用变频调速使其转速降低，节能效果非常明显。而传统的风机、泵类采用挡板和阀门进行流量调节，电动机转速基本不变，耗电功率变化不大。据统计，风机、泵类电动机用电量占用电量的31%，占工业用电量的50%。在此类负载上使用变频调速装置具有非常重要的意义。目前，应用较成功的有恒压供水、各类风机、中央空调和液压泵的变频调速。
