Abstract

This paper proposes the transformer less grid tie inverter (GTI) based on boost converter. An inverter is design by cascading of two boost converters. Power MOSFETs are used for the switching of boost converters. Transform less GTI provides best efficiency as compare to other inverters due to small size, and maximum power processing. The proposed topology includes H bridge circuit for MOSFETs; voltage divider circuit, rectifier, dual stage boost converters, and filter circuit which is use for removing harmonic distortion(HD) and swells inverter verified efficiency about to 98% within 0.9KW power. Simulation results for output of boost converters, voltage divider circuit voltage waveforms and inverter output waveforms are shown using MATLAB Simulink software
