Abstract: PROBLEM TO BE SOLVED: To provide a resonant power supply unit using a synchronous rectifying system capable of reducing the voltage drop in a rectifying means disposed on a current doubler circuit, thereby attaining high output efficiency. SOLUTION: Resonance current is generated between a resonant capacitor C4 and a leakage inductance of a transformer to output current on the secondary side of the transformer Tr1. A voltage waveform formed into a sine wave can be obtained across the capacitor C4. The current doubler circuit is disposed on the secondary side of the transformer Tr1, and voltage generated across the capacitor C4 is supplied to the gates of MOS-FETs 3, 4 which are used an the rectifying means included in the current doubler circuit. therefore, the MOS-FETs 3, 4 can be driven without attachment of an additional driving circuit. The MOS-FETs 3, 4 have a lower voltage drop than that of a conventional diode, thus it is possible to increase the output efficiency of a power source extremely.
