摘　　要：通讯设备电源在低压大电流输出时,其整流效率一般小于90%,因而整机效率也只能做到80%左右。为了进一步提高低压大电流输出时的效率,提出了的异步整流技术能解决该问题,异步整流可以使整流部分的效率进一步提高,所以电源整机的效率也相应提高,从而达到节能降耗的目的。When communication equipment power supply works in low voltage and high current output,its rectifier efficiency is typically less than 90%,therefore the machine efficiency can only be about 80%.In order to further enhance the low-voltage and high current output efficiency,the asynchronous rectifier technology was used in this paper to solve the problem.Asynchronous rectification could further improve the efficiency of rectification section,so the efficiency of the power machine correspondingly increased so as to achieve energy saving.
