  • Abstract
    This paper analyzes and compares the most common single-stage transformerless photovoltaic inverter topologies for three-phase grid connection with the main focus on the safety issues that result from the lack of galvanic isolation. The change in the leakage current to ground will be investigated and a comparison of the selected topologies will be carried out, based on the component ratings, output voltage levels and filter size.
