摘要
In a DC power supply in which a DC power source and a transformer are connected via a power conversion circuit and a secondary winding of the transformer is connected to a load via a rectifier diode bridge and a filter circuit to supply power to the load, a resonance reactor is provided on an output side of the transformer, a resonant switch circuit including a parallel circuit of a diode and a semiconductor switch and a resonant capacitor is connected in parallel to the rectifier diode bridge and a snubber circuit including a snubber capacitor, a snubber diode and a diode for discharge is connected to a serial resonant circuit including the resonance reactor and the resonant capacitor in the resonant switch circuit to absorb a surge voltage.
