Abstract:

The suggested converter enjoys a wide output range from almost zero to 50V/20A. The crucial issue of applications with expansive voltage capacities such as cathodic protection applications, electric vehicle (EV) battery chargers, and photo-voltaic inverters is that the zero-voltage-switching (ZVS) is hardly attained at low outputs. The proposed converter employs auxiliary passive components to surmount this problem. Moreover, a parallel capacitor is implemented at the transformer secondary side to decrease the effect of the parasitic capacitors and provide a robust control system with less sensitivity to parasitic elements. Theoretical calculations and simulation outcomes confirm the veracity of the suggested method.
