| 摘 要： | 目前，许多小型家用电器均采用电容降压法来获得供电电源，如超声遥控开关、电子节能灯等，它们的电源电路均是电容降压整流电路，电容降压法虽然具有一定的局限性，但却有很大的实际应用价值，通过电容降压法的原理，分析了电容降压法的适用范围，并给出一种选取降压电容的实用简便方法，利用该方法，可以根据具体线路的要求，快速，准确地确定出所需要的降压电容。

| Abstract: | At present,many kinds of small electric households are supplied with electricity through electric capacity,such as supersonic remote control switchs and energy frugal lamps,which are all powered by the circuits of step down capacity.This method is very practical although it has limitation in application.This paper theoretically analyses the limits of this method,and gives a practical approach to choose the capacity quickly and correctly for a concrete circuit. |
