| 摘 要： | 针对输出整流管反向恢复带来的电压尖峰及电磁干扰等问题,设计了一种改进型尖峰抑制器。该尖峰抑制器能够有效抑制寄生振荡,消除尖峰电压,且损耗小。最后设计制作了一台3kW(15V/200A)ZVS全桥变换器,给出了添加尖峰抑制器前后整流管反向电压的对比波形,验证了所提出改进方法的有效性。

| Abstract: | Aimed at the problems of voltage spikes and EMI caused by the rectifier diodes due to the reverse recovery,an im-proved spikes-suppressor is proposed,which can eliminate the parasitic oscillation and voltage spikes effectively.Fur- ther more,the loss of this spikes-suppressor is extremely low.A 3 kW(15 V/200 A)prototype converter is built in lab and the experimental results verify the effectiveness of spikes-suppressor. |
