In order to further increase power density of residential PV inverter, a Zero-Voltage Switching (ZVS) full-bridge inverter with increased switching frequency of 500 kHz is investigated. According to the loss model, the loss distribution of the ZVS inverter is analyzed. In order to maintain high efficiency at 500 kHz switching frequency, resonant inductor design, optimized modulation of the ZVS inverter...
