Photovoltaic (PV) generation systems are widely employed in transformer less inverters, in order to achieve the benefits of high efficiency and low cost. Safety requirements of leakage currents are met by proposing the various transformers less inverter topologies. In this paper, twotransformers less inverter topologies are illustrated such as a family of Improved H6 & HRE transformer less inverter topologies with low leakage currents is proposed,this paper proposes a new isolated three port bidirectional dc–dc converter with Improved H6 & HRE topologies for simultaneous power management of multiple energy sources. The proposed converter has the advantage of using the least number of switches and soft switching for the main switch, which is realized by using an inductor capacitor inductor (LCL) resonant circuit. The Proposed method is capable of interfacing sources of different voltagecurrent characteristics with a load and/or microgrid. The proposed converter is constructed for simultaneous power management of a photovoltaic (PV) panel, a rechargeable battery, Improved H6 or HRE, and a Single phase Grid. An examination of demand for the proposed inverter, the utility grid, and the PV module are presented. A performance comparison of grid connected Improved H6 and HRE topologies are implemented in MATLAB/Simulink environment. Also an analysis has been presented to select a better topology.
