In the recent years the applications of solar energy and photovoltaic panels PV were increasing rapidly in order to minimize the consumption of traditional fuels and hence decrease the overall kWh generation cost, also to minimize the CO2 emission that is harmful to the environment. The application of large PV panels with transformer-less inverter leads to the so-called discharging current problems associated with natural capacitance between different panels and the ground. Moreover, the presence of the capacitance between different layers of the same panel adds more complexity to the problem. This paper focuses on the performance of a modified H5 bridge for such problems. The proposed single phase solution minimizes the overall natural capacitance and hence attenuating the impact of the harmful leakage current below standard limits with a fast response and low price. Also, the proposed solution is associated with an effective filter in order to increase the effectiveness of such systems. The simulation of uncontrolled and fully controlled with suitable filter was performed in order to validate the proposed method.
