| Abstract: | Described is the working principle of single-ended forward power supply of 3U on-board. With MOSFET as switch components,the power supply is characterized by small cubage,high efficiency and reliability,and more functions of protection. Especially when the power supply shut down,the output is continued which is important to data saving. |
