固定频率全桥DC/DC变换器附加LC谐振链后容易实现零电压开关,通过移相技术实现了从空载到满载变化时输出电压的稳定.详细分析一个周期内的八种操作间隙和四种工作状态,并用很好的实验结果来验证.
The fixed-frequency full-bridge DC / DC converter is easy to achieve zero-voltage switching after adding LC resonant chain, and the output voltage is stable from no-load to full-load through the phase-shifting technology.A detailed analysis of eight operating gaps and four Kind of working condition, and use a good experimental results to verify.
