| 摘 要： | 在需要多电源供电的电路中,传统的实现方法是通过多个变压器变压、整流、稳压的方法实现,或者通过变压器次级多抽头方式变压、整流、稳压方法实现。不仅增加成本,同时使产品体积增大。文章介绍了78XX系列三端稳压电路的改进电路,克服了传统电路的缺点。

| Abstract: | In and stabilize the v order to realize a circuit which requires multiple power supplies, people usually vary, commutate oltages by several transformers or by sub - headed transformers. It will increase the costs as well as the product＇s size. This article will introduce an improved 78XX voltage - stabilizing circuit, which avoids the weaknesses of the traditional circuit and also improves the transforming efficiency. |
