摘要
在电源输入端将传统的二极管桥式整流器改为金属氧化物半导体场效应晶体管(Metal Oxide Semiconductor Field Effect Transistor,MOSFET)桥式整流器及相应的控制线路,可以大幅减少传统二极管桥式整流的导通损耗,且控制线路简单、稳定可靠性高。通过实测数据对比,在一款2000 W的大功率PC电源中,整机效率有所提高,能够轻松实现钛金牌效率的要求。
Changing the traditional diode bridge rectifier into Metal Oxide Semiconductor Field Effect Transistor(MOSFET)bridge rectifier and the corresponding control circuit at the power input can greatly reduce the conduction loss of the traditional diode bridge rectifier,and the control circuit is simple,stable and reliable.By comparing the measured data,in a 2000 W high-power PC power supply,the efficiency of the whole machine can be improved,which can easily meet the requirements of titanium gold medal efficiency.
