| Abstract: | The circuit characteristics of traditional ZVT-PWM Buck converter is analyzed,the analysis result indicates that internal circulating current and auxiliary switch turn-off are increased the switch losses in the converter.To solve this two problems,an improved circuit for eliminating the internal circulating current and reducing auxiliary switch turn-off loss is proposed .It raises the efficiency of the converter significantly. |
