Abstract

This study describes an effective full-bridge, modulated asymmetric converter for solar PV applications. In order to obtain the zero-voltage switching (ZVS) on the power switches from the primary side and to reduce the circulating current loss, the proposed converter adopts a full-bridge topology and an asymmetry control scheme. In addition, the resonant mechanism consisting of the transformer's leakage inductance and the blocking capacitor supplies the Zero current switching (ZCS) off for the output diode without any auxiliary circuits. This removes the output diode reverse recovery problem. Furthermore, the power switch voltage strains are connected to the input voltage. The proposed converter has the framework to mitigate power losses because of these characteristics. It is particularly useful for the structures of renewable energy sources. The 400W system is tested with an input voltage range of 40V to 80V to validate the theoretical study and feasibility of the proposed converter.
