N2 - Photovoltaic (PV) microinverters have been a trending research area due to their modularity, plug-and-play capability, and ability to maximize power extraction from individual PV modules. This article introduces a new non-isolated, single-stage, single-phase high-gain microinverter for PV applications. The proposed microinverter, with its high gain capability, can interface a 35 V DC source with a 230 V AC grid. The topology comprises five switches, with one switch always operating at high frequency and the others operating at high frequency either during a positive half cycle or during a negative half cycle of the output voltage. The proposed microinverter is designed to achieve high voltage gain while operating in continuous conduction mode, and the topology also features dual grounding, resulting in negligible leakage current. The performance of the proposed high-gain microinverter is verified at a 300 W power rating using the MATLAB/Simulink platform.
