In this paper, we discuss the interleaved Flyback Micro-inverter with SiC device. The Micro-inverter is composed of front-end interleaved Flyback converter and a 50 Hz switching MOSFET inverter. A loss model is used to compare the efficiency between using SiC devices and conventional device. Three solutions are compared: Micro-inverter with Si diode, Micro-inverter with SiC diode, and Micro-inverter with SiC MOSFET for synchronous rectifier. Finally, the comparison is verified by experiment.
