voltage multiplier

   Also found in: Wikipedia 0.04 sec.

voltage multiplier

An electronic circuit that converts AC to DC and multiplies the source voltage. Comprised of 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.

voltage multiplier [′vōl·tij ‚məl·tə‚plī·ər]
(electricity)
instrument multiplier
(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.
