浅析“开关稳压电源”(二)

Switch Voltage Regulator(Ⅱ)

文中进一步对开关电源两种主要电路结构———"串联型"/"变压器耦合并联型"开关电源作了比较详尽的介绍,且对比了两者性能的优劣。文章用较大的篇幅分析了一种典型的实用开关稳压电源———E3C机芯彩电应用的关键点与难点:激励脉冲产生电路、自动调节过程与过载保护电路。

This article is a follow-up paper of analysing'to stablize power with switch'.in this article,It further introduces two main circuit stractures of switch power-concatenation style and transformer collpling multiplicity style,and compares their advantages and disadvantages in performances. The author uses most space to analyse a kind of typical and practical switch that can stabilize power-the key points and nodus of practical circuit in E3C chip colour TV set to stimulate puise to produce circuit to regulate circuit automaticly and protect circuit over loadingly.
