摘要：
Nowadays, the study of grid-connected transformerless photovoltaic inverters has been increased, the main aspects considered are the switching pattern, the topology, the filters, and also the controller. Certainly, one of the main concerns is to eliminate or to reduce the leakage current generated by the parasitic capacitance inherent in a grounded photovoltaic system and, therefore, achieve safety requirements. This paper is focused on the leakage current reduction of a three-phase transformerless photovoltaic inverter, by simply changing the connection of the output filter. Simulation results validate the proposal.
