| Abstract: | In the technologies of synchronous rec tification, the rectifier diode is replaced with power MOSFET that has very low turn-on resistance. So the dis sipation of rectifier can be greatly decreased and the efficiency of DC/DC conve rter can be improved and the needs of low-voltage, large current rectification can be met. The basic principle of synchronous rectification is introduced at f irst, and then the design of synchronous rectification DC/DC converter i s expressed in detail. |
