Designing microinverters without transformers enhances system efficiency and power density and reduces cost. However, the transformer removal results in loss of galvanic isolation that leads to leakage current circulation. Recently, there has been wide concern about this leakage current circulation and solutions have been proposed for its reduction. The objective of this paper is to investigate the...
This paper deals with a novel transformerless inverter topology having high efficiency, low leakage current and no zero crossing distortions are encountered. In fact, the proposed topology is based on the conventional full bridge topology with an extra AC bypass branch to short circuit the load when the zero voltage of the control is applied. In this way, the current returning from the filtering circuit...
