前言普通的串联稳压电源,性能比较好,但输出电压和输入电压之间的差值较大。即调整管的射极——集极之间的电压差较大,其最小电压差值约为2—3伏。所以这种直流稳压电源的效率比较低,通常在60～80％。为了提高直流稳压电源的效率,人们设计一种开关电源,使调整管处于开关状态。电源的效率得到提高。其效率通常在75～90％。但线路比较复杂,性能一般不高,是否通过某些途径。可以做到效率高、性能好的直流稳压电源呢?这是设计人员常在考虑的问题。笔者参考一些资料,设计试验了这类直流稳压电源、取得满意效果,现介绍如下。不妥之处请同志们批评指正。
Preface Ordinary series power supply, better performance, but the output voltage and input voltage difference between the larger. Namely adjust the emitter - collector voltage difference between the larger, the minimum voltage difference of about 2-3 volts. Therefore, the efficiency of this DC power supply is relatively low, usually 60 ~ 80%. In order to improve the efficiency of the DC regulated power supply, a switching power supply is designed so that the regulating pipe is in a switch state. The efficiency of the power is improved. Its efficiency is usually 75 ~ 90%. But the line is more complex, the performance is generally not high, whether through some channels. Can be done with high efficiency, good performance DC power supply it? This is the designer often consider the issue. I refer to some information, design and test of such DC power supply, and achieved satisfactory results, are presented below. It is inappropriate to comrades please correct me.
