| Abstract |
A new soft-switching technique for synchronous buck converter is proposed. It utilizes an auxiliary winding of the filter
inductor and an auxiliary capacitor to provide zero-voltage-switching (ZVS) of the power switches and maintain a continuous filter inductor current. The reverse recovery problem of the anti-parallel body diode of the synchronous switch is solved. Moreover, it provides a simple structure and shows a higher efficiency compared to the conventional
synchronous buck converter. Theoretical analysis of the proposed buck converter and the experimental results obtained on 230 W prototype are discussed. |
