Abstract
To reduce leakage current in photovoltaic (PV) systems, this study suggests a transformerless inverter. The proposed inverter construction does away with transformers, which are the main source of leakage current in PV systems. The suggested inverter is controlled via pulse width modulation. MATLAB/Simulink is used to analyze and simulate the suggested inverter structure. According to the simulation results, the suggested inverter reduces leakage current by about 90% when compared to existing transformer-based inverters. By minimizing leakage current, the suggested inverter has the potential to increase the efficiency and reliability of PV systems.
