Claims

[Scope of utility model registration request]

a transformer into which high-frequency power is input to the primary side; one half-wave rectifier diode whose anode is connected to one end of the secondary side of the transformer; and a half-wave rectifier diode whose anode is connected to the other end of the secondary side. a diode rectifier circuit for full-wave rectifying the output power of the secondary side, the diode rectifier circuit having a second half-wave rectifier diode having a cathode connected to the cathode of the one half-wave rectifier diode, and a diode rectifier circuit for full-wave rectifying the output power of the secondary side; In a DC power supply device including a smoothing circuit that is connected and supplies DC power to a load, between one end of the secondary side and the anode of the one half-wave rectifier diode, and between the other end of the secondary side and the anode of the one half-wave rectifier diode. Due to the change in the polarity of the output power, the current between the anode of the other half-wave rectifier diode shifts to an unsaturated current region due to the reverse return time of the two half-wave rectifier diodes, and a high impedance is generated. A DC power supply device that is equipped with a main body and an accelerator.
