Coupled Inductor Based H6 Transformer less Full Bridge Inverter For PV- Grid Systems
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
In this paper a coupled inductor based h6 transformer-less full bridge inverter for pv- grid systems have been proposed. Transformer-less inverters have much importance in grid-tied photovoltaic (PV) generation systems, having the advantage of achieving high efficiency and low cost. Many number of transformer-less inverter topologies have been proposed for the safety requirement of leakage currents. In this paper two types of the proposed H6 inverter topologies are taken as an example for detail analysis and modulation strategy. A single frequency method and double frequency methods have been developed for maintaining the voltage constant at the grid side irrespective of changes in the input voltage. The power losses and power device costs are compared between the proposed H6 topologies. In this paper, a family of coupled inductor based h6 transformer-less full bridge inverter for pvgrid systems with low leakage currents is proposed with MPPT PV systems. Simulation results show that the proposed H6 topology achieves good results, which is slightly worse than that of the H5 topology, but it has higher efficiency than that of H5 topology.
