An electrical circuit includes an input for an AC input voltage coupled to a first inductive element with first and second outputs coupled to respective first and second nodes, and a four-quadrant (4-Q) switch coupled between the first and second nodes. A capacitor is coupled between the first node and a third node, a second inductive element is coupled between the third node and the second node, and a first bidirectional device and a first diode are coupled in series between a positive output node and a negative output node. A first output of the second inductive element is coupled between the first bidirectional device and the first diode. A second bidirectional device and a second diode are coupled in series between the positive output node and the negative output node. A second output of the second inductive element is coupled between the second bidirectional device and the second diode.
