零电压开关型准谐振DC／DC变换器的设计

Design of Buck Zero-Voltage-Switched Quasi-Resonant-Converter

本文讨论了ｂｕｃｋ型半波式零电压准谐振变换器的设计方法，并给出了相应的输出为２０Ｗ，５Ｖ的实验电路、主要器件参数及实验结果．实验与理论吻合较好．

This Paper will give in detail a design procedure of the buck zero-voltage-switched quasi-reso nant converter. A SV / 20W prototype circuit of the buck converter, the Parameters of its main de vices and the experimental results are also presellted. It can be seen that the practical results and thetheoretical predictions are in agreement.
