voltage doubler circuit schematic

A voltage doubler circuit is a type of electronic circuit that converts a single input voltage to an output voltage that is twice the input voltage. This type of circuit is often used to provide a higher voltage than is available from the input source, or to provide a regulated output voltage from an unregulated input voltage.

The basic principle of operation of a voltage doubler circuit is to use two diodes and two capacitors to charge and discharge the capacitors in a way that results in an output voltage that is twice the input voltage. When the input voltage is applied to the circuit, one diode will be forward-biased and the other diode will be reverse-biased. The forward-biased diode will allow current to flow through it and charge the capacitor connected to it. The reverse-biased diode will block current flow and the capacitor connected to it will remain discharged.

As the capacitor connected to the forward-biased diode charges, the voltage across the capacitor will increase. When the voltage across the capacitor reaches the peak of the input voltage, the diode will become reverse-biased and the capacitor will begin to discharge. The other capacitor will then be charged by the current flowing through the reverse-biased diode. This process will continue, with the capacitors alternately charging and discharging, until the output voltage reaches twice the input voltage.

Voltage doubler circuits are relatively simple to construct and can be used with a wide range of input voltages. However, they are not very efficient, as they dissipate a significant amount of power in the form of heat. For this reason, voltage doubler circuits are typically only used in applications where efficiency is not a major concern.

Voltage doubler circuits are used in a variety of applications, including:

Power supplies for electronic devices
Signal generators
Audio amplifiers
DC-to-DC converters
Laboratory equipment

If you are looking for a simple way to increase the voltage of an existing power supply, a voltage doubler circuit is a good option. However, it is important to keep in mind that voltage doubler circuits are not very efficient and they can dissipate a significant amount of power in the form of heat.
