Abstract
In a switching mode power converter coupled between first and second terminal pairs, a first circuit path includes a first inductance and a first switch. A tapped transformer has a first winding coupled across the first inductance and a tapped second winding with a tapped winding portion. A second circuit path includes a capacitance coupled to a second inductance, and the second circuit path is coupled to the first inductance through the tapped winding portion in a third circuit path and through the second winding in a fourth circuit path. During their respective conduction periods, the first switch couples the first inductance across the first terminal pair, a second switch completes a circuit between the second terminal pair and the second circuit path or the third circuit path, and a third switch completes a circuit that includes another of the second circuit path and the fourth circuit path.
