This paper proposes a photovoltaic parallel resonant dc-link soft switching inverter using hysteresis current control. The proposed system includes a dc-link switch for soft switching. When the dc-link switch is turned off, the inverter switches are turned on and off with zero voltage switching using hysteresis current controller. So, all of the switches in the proposed inverter are turned on and off with soft switching. As a result, the proposed circuit can reduce the switching loss. The proposed inverter is verified through the theoretical analysis, simulation and experiment.
