The Rise in power demand with growing population across the world has led to the development of renewable energy sources. Among all the renewable energy sources PV power generation system proves to be more superior and efficient than other renewable sources. Recent innovations in transformer less inverters have proven to be efficient and reliable than conventional ones. Here the proposed transformer less inverter for grid connected PV system has the capability of reducing the leakage currents. It also provides the required reactive power to the system to maintain constant CM voltage. To provide high quality current injection in to the grid, PR controller and fuzzy controller are used. In this study the detailed analysis of the operating modes of the proposed PV transformer less inverter system, analysis of the leakage currents and results in MATLAB simulation are presented.
