The differential protective system establishes the main protection against short circuits occurring on transformer windings. This protective system should operate rapidly when internal faults occur. However, it should not operate under nonfault conditions such as a flowing inrush current. In digital differential relays, differential currents or other required signals are sampled and processed according...
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...
