voltage multiplier

(electricity)
(electronics)
A rectifier circuit capable of supplying a direct-current output voltage that is two or more times the peak value of the alternating-current voltage.

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].
