Voltage Doubler Schematic. The simplest of these circuits are a form of rectifier which take an ac voltage as input and outputs a doubled dc voltage. A voltage doubler is a circuit that uses only diodes and capacitors for raising an input voltage into a higher voltage output twice the magnitude of the input.
This voltage doubling effect is achieved through the use of capacitors. 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. Here during the positive cycle of input voltage the diode d1 becomes forward biased and capacitor c1 becomes charged to vsmax peak voltage.
Classic voltage doubler schematic.
The first capacitor charges up to the input voltage of the circuit. The simplest of these circuits are a form of rectifier which take an ac voltage as input and outputs a doubled dc voltage. 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. A dc voltage doubler or voltage multiplier is a circuit which will increase some volts or double the voltage for example 3v to 5v 6v to 12v or 12v to 24v we can also call it voltage booster circuit.
