Voltage multiplier refers to an electrical circuit consisting of diodes and capacitors which multiplies or increases voltage and also converts ac to dc multiplying of voltage and rectification of current is done using voltage multiplier.

Diode application voltage multiplier. In this section we can look into full wave voltage doubler half wave voltage doubler voltage tripler and finally quadrupler. The voltage multiplier is an electronic circuit that delivers the output voltage whose amplitude peak value is two three or more times greater than the amplitude peak value of the input voltage. A voltage multiplier is an electrical circuit that converts ac electrical power from a lower voltage to a higher dc voltage typically using a network of capacitors and diodes.

Here all through the positive half cycle the forward biased d 1 diode conducts and diode d 2 will be in off. Voltage multiplier circuits are classified as voltage doublers triplers or quadruplers etc depending on the ratio of the output voltage to the input voltage. Qpl diodes military qualified diodes axial leaded and surface mount including jantxjantxv.

These multiplier circuits are of different types like voltage doubler tripler quadrupler etc. Thus it is possible to get 200 vdc from a 100 vpeak ac source using a doubler 400 vdc from a quadrupler. Rectification of current from ac to dc is achieved by diode and increase in voltage is achieved by.

The simplest of these circuits are a form of rectifier which take an ac voltage as input and outputs a doubled dc voltage. The input wave form circuit diagram and output waveform is shown in figure 1. In theory any desired amount of voltage multiplication can be obtained and a cascade of n doublers would produce an output voltage of 2nvp volts.

Hermetically sealed glass high voltage diodes are processed per mil prf 19500 milstd 750 and the application slash sheets 575576 and 577. Any load in a practical circuit will lower these voltages. Voltage multiplier consist of two or more diode rectifier circuits which are cascaded to produce a dc output voltage equal to the multiplier of the applied input voltage.

Half wave voltage doubler. A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the ac peak input for example 2 3 or 4 times the ac peak input. A multiplier circuit that generates a dc output voltage having amplitude twice the maximum amplitude of the ac input supply voltage is known as voltage doublerthe circuit shows its necessity in all such applications where a high level of voltage is required when the input source is of low amplitude.

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 multipliers can be used to generate a few volts for electronic appliances to millions of volts for purposes such as high energy.
