ABSTRACT:
A power supply device which boosts and stabilizes the voltage of a dc power supply includes an oscillator circuit connected to the dc power supply, a voltage multiplying rectifier circuit which rectifies the output of the oscillator circuit and boosts the voltage and an oscillator control circuit which monitors the boosted voltage and stabilizes the boosted voltage by on-off control of the oscillator circuit. The voltage multiplying rectifier circuit includes a voltage storage element, such as a capacitor connected in parallel with the load driven by the power-supply device. When the output voltage of the device exceeds a predetermined reference voltage, the oscillator control circuit turns the oscillator circuit off. The voltage storage element is thus no longer supplied with electric energy and begins to discharge through the load thereby lowering the output voltage of the device. When the ouput voltage falls below the predetermined reference voltage the oscillator control circuit turns the oscillator circuit on again to repeat the voltage stabilization cycle.
