Topological Structure of Main Circuit Inverter Based on Soft-Switching Technology and Parameters Adaptive

This paper presents a new topology of main circuit based on soft switching technology of ZVS-PWM. At present, hard switching is applied in most inverters. Because the switching power isnt equal to zero, a great number of losses on the switching are generated when the switching at a high frequency. To solve the fault of hard switching, this paper presents that apply the inverter circuits based on soft switching technology of ZVS-PWM to high frequency APF, which will decrease switching losses and noise greatly. The proposed topology and operation principle of the control method is discussed in detail, finally simulated results verify the effect of research.
