13+ Dc Voltage Doubler Circuit Diagram. A voltage doubler application is a dc power supply capable of using either a 240 vac or 120 vac source. A multiplier circuit that produces dc output voltage whose amplitude is twice the maximum amplitude of the ac input supply voltage is known as voltage doubler.
During the negative half cycle of the sinusoidal input waveform, diode d1 is forward biased and conducts charging up the pump capacitor, c1 to the peak value of the input voltage, ( vp ). This voltage doubler circuit uses a dpdt switch to alternately charge 2 series connected capacitors. Other applications are up to you !

13+ Dc Voltage Doubler Circuit Diagram. This symbol ( )is used to indicate a capacitor in a circuit diagram. The circuit shows its necessity in all such applications where a high level of voltage is required when the input source is of low amplitude. First the output must be reduced to a scaled low voltage through. It's output voltage is a fixed fraction of its input voltage.
