Range Extension of Input Voltage of Flyback Inverter for Photovoltaic AC Modules

PV-AC 모듈형 단상 플라이백 인버터의 입력 전압 범위 확장 기법

Among the PV-AC module topologies, the flyback inverter have been occupied the attention due to its simplicities on configuration and control. Proposed switching control method changes the mode of operation in DCM and BCM alternatively. It is expected that the high performances in efficiency and extension of input voltage range can be achieved by the conduction mode change. Proposed switching technique is validated by PSIM simulation.
