Voltage Multiplier Circuits with explanation | 4 types

Voltage multiplier circuits are electronic circuits that multiply the input voltage 2 to 3 or 4 times, and the output voltage RMS is also 2 to 4 times higher. This kind of circuitry basically employs just some diodes and capacitors. It takes AC input and then converts that to higher Amplitude DC voltage. The voltage […]
