An Uni-directional Single Stage Single Phase Soft-Switched Resonant High Frequency Link Inverter

In this article, a single stage high frequency link unidirectional single phase inverter topology is reported for the application of grid integration of solar and fuel cells. The inverter supports only unity power factor operation. The converter is realized using a parallel resonant structure followed by a full bridge unfolder. This avoids undesirable voltage stress caused by parasitic ringing in ...
