Abstract

Transormerless inverters are attractive solution for the grid connected photovoltaic (PV) systems.Unfortunately, it has issues on galvanic isolation between PV systems to the grid. When the galvanicisolation disappears from the PV inverter, leakage currents will flow in a resonant circuit formed by theground capacitance, the converter, the ac filter and the grid. In order to avoid the leakage currents, varioustransformerless inverters have been proposed using different topologies to generate constant commonmode voltage. In this paper, various recently-proposed transformerless PV inverters are investigated. Theirperformances are compared and analyzed.
