Patent attributes
A power converting device converts a DC voltage input from an external power source into an AC voltage output across an output capacitor of an output circuit, and includes a coupling circuit having series first and second windings. A rectifying diode has a grounded anode coupled to an anode of a clamp diode, and a cathode coupled to the second winding. A cathode of the clamp diode is coupled to a clamp switch and the first winding. A full-bridge circuit includes a first series connection of first and second switches, and a second series connection of third and fourth switches. The first and second series connections are coupled in parallel between the first winding and ground. The output capacitor is coupled between a first common node between the first and second switches, and a second common node between the third and fourth switches.
