What is Voltage Multiplier? 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.

AdvantagesLow CostProduce High VoltageAlternative of Transformer

Types of Voltage MultiplierDepending on the output voltage, multipliers can be of different types

Voltage Doublers Voltage Tipplers Voltage Quadrupler
