Reconstructive line modulated resonant converter

A resonant power converter configured to receive as input a varying input voltage from an input voltage source and to output an output voltage, the resonant power converter comprising:

• a. a transformer having a primary winding and a secondary winding, wherein the secondary winding is coupled to an output of the resonant power converter;
• b. a first switch comprising a first terminal, wherein the first terminal is coupled in series to the primary winding;
• c. a second switch coupled in series to the first switch;
• d. a first resonant tank coupled in series with a third switch, wherein the series coupled first resonant tank and third switch are coupled in parallel across the second switch;
• e. a second resonant tank coupled in series with a fourth switch, wherein the series coupled second resonant tank and fourth switch are coupled in parallel across the series coupled first switch and second switch;
• and
• f. a signal processing circuit coupled to the input voltage supply, to the first terminal of the first switch, and to each of the first switch, the second switch, the third switch, and the fourth switch, wherein the signal processing circuit is configured to sense the input voltage and a first terminal voltage, and to selectively drive each of the first switch, the second switch, the third switch, and the fourth switch according to the sensed input voltage and first terminal voltage.
