About: electrical and electronics engineering student

let's have a view on circuit diagram

Supplies:

Step 1: Components Required

1) Diode 2
2) Capacitors 2
3) Connecting wires
4) Bread board
5) Multimeter
6) ac source 12 v

Step 2: Description

give the connection as per the circuit diagram, the two violet wires are used to check the output.

Step 3: Testing

We got the doubled output..
hope you guys enjoyed..

if you guys have any doubts comment below..!

    If you run a Bridge Rectifier, and test the voltage in AC on your multimeter, it will read double the voltage, but it is not truly doubled.

    Dude, this circuit is of ac full wave rectifier. I wonder how you are getting "voltage doubled" that to in AC??

    This is not a full wave bridge recifier. a full wave bridge rectifier would use four diodes and no capacitors and the diodes would be two in series parallel to another two in series, tapped in the middle of each series.

    hey dude.. can u explain how i can get 15v from dc motor using voltage tripler or voltage double.my dc motor produce 5v only..can u sent circuit at andy89_tgkk@yahoo.com

    You might wanna mention that you need large capacitor values to get a decent output current with this configuration. It can be used for low current bias and such, but if you need a higher voltage, it's generally better to use another transformer.

    Here is the correct schematic.

    Buddy of mine who is 'into wires' made one of these for me to power an electric fence with an automotive coil. It worked great. We plugged an electric drill into it and the drill would twist out of my hand when the trigger was pulled. Fun stuff!!!!

    The schematic diagram shows both sides of the output coming from the same node. The output voltage will be zero volts. The photos of the breadboard do not match the schematic. The breadboard photos show the output coming from only one capacitor. The output will be sqrt(2)* input voltage and it will be DC, not AC. The correct circuit takes the output from the cathode of the upper diode and the anode of the lower diode. It will be 2* sqrt(2) * input voltage and it will be DC.

    ehacker this circuit is an ac boosting circuit. with which we can only boost the ac supply. if you wanna check DC it will be in vain. this is not an rectifier circuit to get dc.

    It's not an AC boosting circuit. Here are several ways you can verify this.

    1. I suspect your voltmeter responds to DC even though it's set to the AC range. What does the voltmeter show if you measure "AC volts" of a 9V battery?

    2. You're an electronics student? Do you have access to an oscilloscope? An oscilloscope will tell you the true story.

    3. Try actually putting 33 VAC across an inexpensive aluminum electrolytic capacitor. For that matter, try just putting your 12 VAC directly across one of those capacitors. See what happens.

    4. Ask one of your instructors if you don't believe Omnivent and I.

    thanks hacker for your valuable comment.. you er right ma mm respond to ac even it is a DC source. sure I will check it with oscilloscope once ma semester holidays over. could you explain what the above circuit is.? plz
