voltage multiplier

An electronic circuit that converts AC to DC and multiplies the source voltage. Using capacitor/diode pairs, the capacitor stores the source voltage like a charge pump, and the diode rectifies it. The output voltage is roughly the input voltage times the number of capacitor/diode pairs; for example, a voltage doubler uses two capacitor/diode pairs. A voltage tripler uses three pairs. See charge pump and rectifier.

Circuit Description of The Cockcroft Walton Voltage Multiplier Dc-Dc Converter:
Transistors [M.sub.3,4] and [M.sub.5,6] are to function as an adder as first proposed by [22] in the use of low voltage multipliers. Under the correct bias conditions, it follows that [mathematical expression not reproducible], and then given that both [M.sub.1] and [M.sub.2] have the same [v.sub.ds] and each drain current is governed by [mathematical expression not reproducible] and [mathematical expression not reproducible], the total current [I.sub.t] through [M.sub.1] and [M.sub.2] simplifies to [mathematical expression not reproducible] or an equivalent resistance of [mathematical expression not reproducible].
The series is also suited for use as snubbers, resonators, filters, or DC blocking caps in automotive, medical, industrial, and commercial electronics, including displays, high voltage multipliers, high frequency power converters, and SMPS.
