|
This paper presents newly developed transformer-less single phase inverter for photovoltaic (PV) power system. When grid connected photovoltaic system is transformer-less, a galvanic connection between the grid and PV array exists. In these conditions, common mode leakage currents can appear through the stray capacitance in between PV array and the ground. In order to avoid these leakage current, different inverter topologies are used which generate constant common mode voltages. The two different control techniques are used to eliminate common mode leakage current. These current increase harmonics injected in the utility grid and losses. |
