摘要
在专业级别或商用的开关电源适配器一般都需要全范围的过流/过载保护电路,然而过载保护电路一直是开关电源适配器的设计和调试难点;详细给出了过载保护电路的类型,设计的基本思路,实际的例子,调试时应遵循的方法。
Most of switching mode power adaptor in professional or commercial grade includes over current （load） protection in all the prevailing input and output conditions. However such circuitry is the most demanding challenge in designing and debugging during development process. The various type of OLP, and its basic design concept as well as the actual design implementation and methods to be followed during debugging are presented.
