Sep 27, 2018 at 7:59. I agree with @jsotola comment but more precise: the output voltage can be a DC voltage assuming there''s a smoothing capacitor and you do not load the DC output. Then assuming the rectifier diodes have zero voltage drop (that will never be the case) then the DC output voltage will be 2–√ 2 the AC input voltage.

A voltage multiplier is a specialized rectifier circuit producing an output which is theoretically an integer times the AC peak input, for example, 2, 3, or 4 times the AC peak input.

Apr 5, 2021. #1. Playing around with voltage multipliers and modeling a doubler and ran into something that is counterintuitive for me. I normally think of using large capacitors (470-1000uF) to smooth the ripple for converting AC to DC. Instead, modeling it I come up with 0.1uF as giving me a very low inrush current and millivolt output ripple!

The magnitude of the voltage depression and ripple is of course due to the effect of a load current, and will be given by: Vr = t*I/C. where Vr is the ripple voltage, I the load current and t the half-period.
