Abstract
A resonant power converter includes a DC power source a pair of MOS-PETs and which are connected in series to the DC power source, a transformer Tr which is arranged at the subsequent stage of the MOS-FETs and and includes a primary coil and a secondary coil, a capacitor C is arranged in parallel with the secondary coil of the transformer Tr so that series resonance occurs between the leakage inductance of the transformer Tr and the capacitor C A current doubler rectifier circuit may be arranged in the subsequent stage of the capacitor C Further, a pair of switching elements for synchronous rectification may be provided in the subsequent stage of the capacitor C so that these switching elements are driven by drive signals responsive to a voltage generated across the resonance capacitor C
