Abstract
(EN)
A power supply device provided with: a transformer; a series circuit that is connected between the terminals of a commercial power supply and composed of 2 bidirectional switching elements having a rectification function and a switching function; an LC resonance circuit that is connected between the both ends of one of the bidirectional switches and the primary winding of the transformer; rectifying devices that are connected to the secondary winding side of the transformer; and a control circuit that inputs a gate driving signal to the bidirectional switching elements. Synchronous rectification is performed by the bidirectional switching elements.
