A voltage doubler is an electronic circuit which charges capacitors from the input voltage and switches these charges in such a way that, in the ideal case, exactly twice the voltage is produced at the output as at its input. ... Voltage doublers are a variety of voltage multiplier circuit.

How does a voltage doubler circuit work?

A voltage doubler is an electronic circuit that produces an output voltage that is double the input voltage. ... The circuit is formed by an oscillating AC input voltage, two capacitors, and two diodes. The input voltage is AC, and the output is DC voltage with twice the peak value of the input AC voltage.

How does a DC voltage doubler work?

The Voltage Doubler. ... This simple diode-capacitor pump circuit gives a DC output voltage equal to the peak-to-peak value of the sinusoidal input. In other words, double the peak voltage value because the diodes and the capacitors work together to effectively double the voltage.
