Voltage DoublerĪ voltage doubler application is a DC power supply capable of using either a 240 VAC or 120 VAC source. We’ll first go over several types of voltage multipliers-voltage doubler (half- and full-wave), voltage tripler, and voltage quadrupler-then make some general notes about voltage multiplier safety and finish up with the Cockcroft-Walton multiplier. Any load in a practical circuit will lower these voltages.

Thus, it is possible to get 200 VDC from a 100 Vpeak AC source using a doubler, 400 VDC from a quadrupler. A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the AC peak input, for example, 2, 3, or 4 times the AC peak input.
