摘　　要：从分析各种引起损耗的原因着手,在AC/DC变换器中,做了进一步提高开关电源工作效率的可行性分析,指出了提高开关电源效率的途径,同时提供了设计方法和进一步完善的建设性思路。From AC/DC converter point of view, the thesis will further analyze the possibility of improvement of switching power supply. The paper will illustrate the various causes in the inefficiency and find out the solution of prevent on - off electric source from being inefficiency. The paper also comes up with specific designs and constructive notions.

关 键 词：开关电源 工作损耗 变换器效率 无源软开关 同步整流
