基于混合ZVS的不对称半桥变换器研究
Research on Asymmerical Half Bridge Converter Based on Hybrid ZVS Method
摘要
Abstract
The shortcoming of traditional asymmetric half bridge converter with transformer primary side series resonant inductor or transformer magnetizing inductance energy that achieve zero voltage soft switch was analyzed,one hybrid soft switching mode used resonant inductor and magnetizing inductance in under different load was researched. The soft switching process in light load and heavy load and half load conditions was analyzed,soft switching mechanism was investigated with resonant inductance and magnetizing inductance in different load. The results of simulation and experiment verify that the hybrid ZVS only needs magnetizing inductance and smaller resonant inductance to realize soft switching in wide load range,the soft switching characteristic is good and the efficiency is high.关键词
