Claims

[Scope of utility model registration request]

A first rectifier circuit having a capacitor and rectifying a half cycle of the AC power supply; a second rectification circuit rectifying the other half cycle of the AC power supply to charge the capacitor;
In a rectifier circuit comprising a voltage doubler rectifier circuit in which the charged voltage of the capacitor of the rectifier circuit is multiplied by the capacitor of the first rectifier circuit, the rectifier element of the second rectifier circuit is controlled. A rectifier circuit comprising a control circuit that turns off the control rectifier and switches to an equal voltage rectifier circuit when a detection voltage of a detection circuit that detects an AC input voltage or a DC output voltage is equal to or higher than a predetermined value. .
