将AC 电源以全波整流的方式转换为DC,由变压器所计算出的Iin值,可知只要使用1A/600V 的整流二极管,因为是全波整流所以耐压只要600V 即可。 3.3.8 C1(滤波电容): 由C1 的大小(电容值)可决定变压器计算中的Vin(min)值,电容量愈大,Vin(min)愈高但价格亦愈高,此部分可在电路中实际验证Vin(min)是否正确,若AC...
电源按照转换原理分类,可分为线性电源和开关电源。我们对电源进行线性电源和开关电源分类的时候,其实要明确是AC/DC还是DC/DC。虽然这个分类是为了区分转化的原理。但是实现AC/DC功能的线性电源和开关电源,都是完整的交流转化为直流的过程吗,其中有些电路的一部分就是由DC/DC组成的。 2022-10-08 09:23:24 什么...

That doesn't look like power supply ripple ... It's not ripple, it's the switching noise that passes to the output. The question is: How to filter the output switching noise? 🤔 stv said: some dc/dc converters leave out switching cycles at low currents which lowers the ripple fre...
