摘　　要：针对典型的BoostZCT-PWM变换器中存在的主开关管硬开通和辅助开关管硬开关的问题,对原电路作了改进,提出了一种新的控制方法。实验结果证明,主开关管和辅助开关管均实现了零电流开通和关断,且进一步改善了变换器的工作状况。Aiming at the problems of the main switch turning on and the auxiliary switch working under hard switching conditions in a typical Boost ZCT-PWM converter, some improvements of the circuit are made and a new control method is introduced in this paper.Experimental results verify that all switches turn on and off under zero-current condition and the working condition of converter is improved.
