陶显芳开关电源原理与设计系列

开关电源就是利用电子开关器件（如晶体管、场效应管、可控硅闸流管等），通过控制电路，使电子开关器件不停地“接通”和“关断”，让电子开关器件对输入电压进行脉冲调制，从而实现DC/AC、DC/DC电压变换，以及输出电压可调和自动稳压。-Tao Xianfang principle of switching power supply switching power supply design series is the use of electronic switching devices (such as transistors, FET, SCR thyratron, etc.), by the control circuit, electronic switching devices kept " ON"　and " OFF , electronic switching devices of the input voltage pulse modulation, in order to achieve a DC/AC, DC/DC voltage conversion, and adjustable output voltage and automatic voltage regulator.
