GaN based transformer-less microinverter with coupled inductor interleaved boost and half bridge voltage swing inverter

Due to their plug and play feature, easy installation, and higher power yield under partial shading conditions, microinverters have gained popularity in the roof-top-PV market. This paper explores a converter system for the transfomer-less microinverter with coupled inductor based interleaved boost as the dc-dc stage and half bridge voltage swing (HBVS) inverter as the dc-ac stage. The dc-dc stage is capable of offering high gain with a flexible...
