A cascade voltage multiplier circuit converts the lower AC voltage to a higher DC voltage. Typically, this circuit is using a network of capacitors and diodes. ... The output DC voltage is 400 V, and it reach this value after about 1 second. This type of half-wave voltage multiplier circuit is also called Villard cascade.

What is Villard circuit?

Villard circuit

Essentially, the circuit is a diode clamp circuit. The capacitor is charged on the negative half cycles to the peak AC voltage (V_pk). The output is the superposition of the input AC waveform and the steady DC of the capacitor. The effect of the circuit is to shift the DC value of the waveform.

What is Cascade voltage doubler?

Abstract. For more than eight decades, cascade voltage-doubler circuits are used as a method to produce DC output voltage higher than the input voltage. In this paper, the topological developments of cascade voltage-doublers are reviewed. A new circuit configuration for cascade voltage-doubler is presented.
