Diode Voltage Doubler Circuits

Faulty voltage doubling/tripling circuit?

I was building a voltage tripling circuit from www.coolcircuit.com/circuit/voltage/ (3rd schematic from the top). After constructing it with 1uF 350v capacitors and 3A 500v diodes, I noticed I was getting roughly 480vdc, not the expected 360vdc. With no other choice, I built the voltage doubler, 2nd schematic from the top on the same page. It turned out to output 320vdc, neither the expected 240vdc nor 360vdc. Are the schematics simply wrong or are my components' ratings somehow amping up the voltage? (hah! pun!) I triple checked each of the completed circuits for accuracy.

The voltage of power outlets is designated in _effective_ voltage. I.e. you calculate with about 120V, but the peak voltage is a lot more, approximately 160V, and that's what drive the voltage doublers/triplers. At least under optimal circumstances and no load.

160V * 3 = 480V
160V * 2 = 320V

Looks okay to me. Hook up some load to the output and see if the voltage drops. If it doesn't drop sufficiently, put a potential divider after the doubler/tripler.

Voltage Doubler $54.86 High Quality Content by WIKIPEDIA articles A voltage doubler is an electric circuit with an AC input and a DC output of roughly twice the peak input voltage. They are a variety of voltage multiplier circuit and are often, but not always, a single stage of a general form of such circuits. The term is usually applied to circuits consisting of rectifying diodes and capacitors only, other means of doubling voltages are not included.The Villard circuit consists simply of a capacitor and a diode. While it has the great benefit of simplicity, its output has very poor ripple characteristics. Essentially, the circuit is a diode clamp circuit.

Transmission Lines and Schottky Diode $108.33 A nonlinear relation between current and voltage for schottky resonant tunneling diode is used. A general form of equation similar to VanDer Pol equation is obtained. A Resonant tunneling diode(RTD) has a negative differential resistance that means when the voltage increases the current decreases. This property is very useful for oscillators manufacture. Nonlinear transmission lines is considered to show that it canbe used in oscillators and to show that it can reshape the sinusoidal signals to othershapes by using OrCad and mathematica programming.

A transformer supplies a.c. to a circuit shown in the figure. Its primary side is connected to a 230 V, 50 Hz, a.c. voltage source and has a turn ratio of 1:2. The capacitors are both 0.1μF.
(i) Identify the circuit configuration.
(ii) Determine the open-circuit dc output voltage, VL (with RL disconnected).
(iii) Find the peak reverse voltage rating needed for each diode.

1) you already did, full-wave voltage doubler

2) Secondary voltage is 460 volts RMS, peak is 1.4 times that, or 644 volts.
You will get the peak voltage out as DC, for each half of the circuit, minus a volt for the diode. You add the two together to get DC out, or 2 x 643 = 1286 volts DC.

3) Each diode needs to handle 2x 644 volts or 1288 volts.
