The single stage transformer-less micro-inverters are being preferred because, their power conversion efficiency is high. A new single stage transformer-less micro-inverter topology is proposed in this paper which can generate an ac output of 220 V from 35 V PV module. In this topology, it has been achieved that, the voltage across the PV terminals are not polluted by 100 Hz ripple, which is generally the limitation encountered by the converter interfacing single phase ac with the dc system. In this topology, the PV ground is shorted with the neutral of the grid, and hence the magnitude of the leakage current is negligible. The viability of the proposed converter is verified by performing detailed simulation studies on MATLAB/Simulink platform.Read More
