One is that the operation duty cycle can not be larger than 50 % because of the requirement for the transformer resetting . as a result , the voltage stress of the secondary diode is high , which limits the usage of dfc in high output voltage application 但由于变压器磁芯复位的需要，其工作占空比必须小于50 ，从而造成占空比利用率不高，变压器副边电压高，副边高频整流二极管的电压应力大。
A current - doubler - rectifier ( cdr ) zvs pwm ( half - bridge ) three - level converter is proposed in this paper . zvs can be achieved for all the switches in a wide load range with the use of the energy stored in the output filter inductances . the output rectifier diodes commutate naturally without voltage oscillation and voltage spike 针对传统(半桥)三电平直流变换器的一些不足，本文提出一种倍流整流方式pwm零电压开关三电平直流变换器，可以使开关管在全负载范围内实现零电压开关，副边整流二极管无电压尖峰，无占空比丢失。
The converter not only keeps all the characteristics of the basic zvs pwm h - fb tl converter , but also eliminates the voltage oscillation and voltage spike across the rectifier diodes in both three - level mode and two - level mode , leading to a reduced voltage stress of the rectifier diodes 本文在基本zvspwmh - fbtl变换器中引入两只箝位二极管,无论是在三电平模式还是在两电平模式,都可以消除输出整流二极管反向恢复造成的电压尖峰和振荡,降低了输出整流管的电压应力。
