Villard-Circuit

The Villard circuit consists simply of a capacitor and a diode. While it has the great benefit of simplicity, its output has very poor ripple characteristics. Essentially, the circuit is a diode clamp circuit. The capacitor is charged on the negative half cycles to the peak AC voltage of 325V. 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. The negative peaks of the AC waveform are "clamped" to 0V by the diode, therefore the positive peaks of the output waveform are 650V. The peak-to-peak ripple is an enormous 650V and cannot be smoothed unless the circuit is effectively turned into one of the more sophisticated forms. This is the circuit used to supply the negative high voltage for the magnetron in a microwave oven.

This is a simple half wave rectifier, not a villard miltiplier

@WTFCircuit, its both in one circuit. It depends on were you place the zero volt reference (ground symbol) http://everycircuit.com/circuit/4752971499307008 sometimes things looking totaly different from a different point of view. But they are still what they are.
