但是它的一个固有缺陷是功率晶体管截止期间变压器必须磁复位，因而需要采用附加的复位电路。
One inherent limitation of the forward converter is that the transformer must be reset during the power transistor off period. Thus, additional reset circuitry has to be used.
通过采用推挽变压器和两个附加的二极管，该变换器可以实现零电压开关，并且有较高的可靠性。
By using two additional diodes and a push-pull transformer, this converter achieves not only ZVS of all active switches but also high reliability.
