voltage doubler

voltage doubler

[′vōl·tij ‚dəb·lər]
(electronics)
A transformerless rectifier circuit that gives approximately double the output voltage of a conventional half-wave vacuum-tube rectifier by charging a capacitor during the normally wasted half-cycle and discharging it in series with the output voltage during the next half-cycle. Also known as doubler.
