...photovoltaic (PV) ac module application. This study presents atwo-switch flyback inverter followed by a low frequency unfolding bridge for fractional horse power water pumping systems. This topology mitigates the problem of high-voltage transients at switch turn off which commonly exists in single switch flybackinverters. Moreover, the proposed control strategy
