Voltage Tripler
A voltage tripler is a type of electronic circuit which is made in such a way that it makes the voltage of an alternating current or alternating signal three times of input value. It uses a combination of diodes and capacitors to gain this type of voltage multiplication. This type of circuit also has a series of charging and discharging cycles through capacitors during different cycle of the AC signal. By making some proper connections of the components the voltage tripler produces an output voltage which is approx three times the value of the input AC voltage. This type of circuit is mainly used in high voltage applications because a high DC voltage is required.
Working of Voltage Tripler
- During the positive cycle diode D1 is forward biased and the diodes D2 and D3 are reverse biased due to which the capacitor C1 gets charged.
- During the negative cycle diode D2 is forward biased and other diodes are reversed baised due to this the Capacitor C2 gets charged. As the voltage across the capacitor C1 and the secondary transformer are additive in nature this makes the capacitor C2 also charge.
- During the another positive cycle capacitor C1 keeps its charge and hence the diode D1 does not conduct and capacitor C3 is not charged then due to this the conduction path for the positive cycle will be Capacitor C1, Capacitor C3, Diode D3 and Capacitor C2.
- Since D3 is forward biased capacitor C3 will charge 2 times which is the sum of secondary of transformer and voltage across the Capacitor C1. After taking the voltage across Capacitors C1 and C3 the voltage will be the sum of its individual capacitors. Therefore, the circuit functions as a voltage tripler..
