Voltage Quadrupler
A voltage quadrupler is an type of electronic circuit which is made in such a way that the voltage of an alternating current or alternating signal becomes four times of its input value. This circuit consists of a combination of diodes and capacitors to gain voltage multiplication. This process involves charging and discharging cycles in the capacitors during different cycles of the AC signal. After making proper connections of the components the quadrupler provides an output voltage that is approx four times the value of the input signal. This is type of circuit which is mainly used in applications where there is a need high DC voltage and also it provides a simple and also a very better way of achieving voltage multiplication.
Working of Voltage Quadrupler
- During the positive half cycle the diode D1 and D11 gets forward baised and hence they conduct which allows the capacitors C1 and C11 to charge from voltage of the input.
- During the negative half cycle the diode D2 and D22 gets forward baised and hence they conduct which allows the capacitors C2 and C22 to charge to the voltage of the input.
- Now during the next positive half cycle the input voltage becomes more positive due to which diode D1 and D11 become reverse biased and the voltage which is present across C1 and C11 gets doubled up which effectively doubles the voltage.
- Similarly during the next negative half cycle diode D2 and D22 become reverse biased and due to this the voltage across C2 and C22 gets doubled up which doubles the voltage.
- Hence there is a repetition of this process with positive and negative half cycle which leads to doubling the voltage across the capacitors.
- After finishing all the process the voltage across the load is four times of given input signal hence voltage gets quadrupled.
