Abstract
Abstract The specification discloses a voltage multiplier comprising a plurality of multiplier stages. Each stage includes a first AC line, a second AC line and a diode line which is interposed between the first and second AC lines. Each multiplier stage includes a plurality of capacitors interconnected to the AC lines and the diode line. The input to the multiplier stages comprises first and second transformers. The primary windings of the two transformers are connected in parallel to receive an AC input signal. The secondary windings of the transformers are connected at a grounded center tap, which is also connected to the diode line. The first transformer drives the first AC line and the second transformer drives the second AC line. The AC input signal is multiplied by each stage, and the multiplied voltages are tapped through a rectifier connected to the diode line to provide a DC output voltage.
