摘要
提出了一种新的恒频隔离式变流器,该变流器采用1个耦合电感来实现整个线路和负载范围内主开关的零电压切换。由于该耦合电感并未以1个串联电感的形式出现在负载电流通道内,故不会产生负载的周期损耗,也不会在输出整流器两端产生严重的电压振荡。该变流器的性能在1个1kW的实验原型电路中得到了证实。
A new constant-frequency isolated converter was introduced in which a coupled inductor was used to achieve zero-voltage switching (ZVS) of the primary switches in the entire line and load range.Since the coupled inductor didn't appear as a series inductance in the load current path,it didn't cause a loss of duty cycle or severe voltage ringing across the output rectifiers.The operation and performance of the proposed converter are verified on a 1 kW prototype.
