Abstract :
Leakage current suppression for a transformerless zero voltage switching (ZVS) full-bridge inverter is investigated. The leakage current model and the common mode voltage of the ZVS full-bridge inverter are analyzed. The leakage current flowing through the parasitic capacitor between PV panels and the ground is reduced by a common mode inductor and the bypass capacitors. The theoretical analysis of proposed method is presented. Finally the leakage current suppression is verified by simulation and experiment.
