摘要
为拓展实现隔离式开关电源的新方法,总结了隔离式开关电源的特点,分析了降压型斩波电路与升压型斩波电路,并在斩波电路基础上,设计了一种新型隔离式可调开关电源,通过调节变压器输出级开关管的占空比实现电压可调,该隔离式开关电源并具有过载保护和短路保护功能。
In order to develop new methods to achieve isolated switching power supply, characteristics of isolated switching power supply have been summarized and the buck chopper circuit and boost chopper circuit have been analyzed. Based on the chopper circuit, a new design of isolated adjustable switching power supply has been finished, and output voltage can be changed with tuning the duty cycle of the transformer output stage switch. The isolated switching power supply also has functions of overload protection and short circuit protection.
