Voltage Doubler Circuits

[rbcastillo]

Does DC exist in nature? Ex. lighting, carpet static, aurora, electric eels, solar flare bursts, fire flies, botton quark, brain waves, nerve impulses. Are these all AC? Lighting seems to build up large + charge then release to ground. Maybe you can explain current flow vs voltage flow. I love your relaxed style.

@rbcastillo

I'm not sure about brain waves. Voltage does not flow it is only electronic that flow and that is when there is current. Voltage is the amount of potential avaliable, like a battery. When the battery is in use, that is when electrons (current) flows.

Hello there,

I am new at this game, hence I need your help; I hope you will.

I am confused at the voltage doubler drawing. You show the capacitor with a curved line, is that the positive side or negative? Now the diodes; I thought the symbol as configured in the drawing the current would flow the direction of the arrow.

The crunch question now; is there a way of stabilizing the voltage produced by the Torroid J-T? I can get sixty V, but as soon as I connect a led bulb it drops to "nothing"

[AllAmericanFiveRadio]

@TheJG1947

It does not really matter, if the capacitor is polarized the positive plate should be marked, sometimes both the positive and negative are marked.

Electrons flow from negative to positive and against the arrow. This is easy to prove, with a diode, a battery and a lamp.

Good  Explanatio..."Thank You"

[AllAmericanFiveRadio]

Thanks anjanagopi666

[pon4iks]

Rly well explained! thx for information. Keep up the good work ;)

[AllAmericanFiveRadio]

Thanks pon4iks

[alitou001]

can anyone explain to me how current flow (+ to -) or (- to +) ,and does the same way the current flow for ac or dc ?or is there a difference? sorry but I am a little confused

[AllAmericanFiveRadio]

Electrons in a circuit flows from negative to positive and nobody really knows why. AC changes direction in a circuit and DC does not. But if it is AC or DC, electrons in a circuit flow from the negative to the positive potential.

[alitou001]

@AllAmericanFiveRadio Thank you for clarifying this to me.

[QuarkToo]

@AllAmericanFiveRadio I know why electrons flow towards positive. You have to understand that electricity is mass to atomic energy conversion and how that process works.

Once you understand that and how to use a shorted coil to produce compression/acceleration, you understand that free energy devices are easy to build and understand. The universe produced that mass from energy and it takes far less energy to convert that massive energy into potential.

Good video BTW.

I was taught that nature abhors a vacuum and that electrons will flow to a place where there is a lack of electrons via the easiest route. The easiest way is through a conductor. In electronics the + or positive side has a lack of electrons and the - or minus side has a bunch of electrons. The greater the difference between the two the higher the voltage. The more electrons able to flow from the - to the + the higher the current.

[QuarkToo]

@nckeller

True and that vacuum was created when the mass of the copper wire was cavitated (Ahanov Bohm effect) The shockwave from that cavitation is what we call voltage and the reason for the speed amplification to light speed - the speed and pressure of the universe.

Electrons flow toward that cavitation to fill in the hole left by the cavitation.

@alitou001

If you think about current which is more practical, it flows from +ve to -ve.Forget what happens to electrons.Most of western academicians understand the electron way of flow which is the other way.So donot get confused.Think only the current flow way ie fro +ve to -ve

[AllAmericanFiveRadio]

Don't know when I will get to it. But I have put it in the YouTube video to do list. Thanks!

[rrangana11]

I have seen these circuits in Fisher tube receivers like 500C and 800B types.

[AllAmericanFiveRadio]

That is very interesting. The only equipment I have seen these type of circuit in is gas tube lasers and tube Gieger counters. Thanks.

[rrangana11]

It is used to generate the plate voltage and it is 430V in those receivers.

[AllAmericanFiveRadio]

Don't know I do not have a wiring diagram. Voltage multiplier circuits are used to produce high voltage @ low current.

[Lockemeister]

Actually learned about this today from your video I meant to say. Thanks!

[Lockemeister]

I never heard of this circuit before. I'm glad you made this video because I actually learned about this today. Very nice presentation.

[AllAmericanFiveRadio]

Thanks. You don't see these circuits that often because of there low current output. But they are interesting and useful.

[GFS6666]

Thank you VERY much for this video. I've always wondered how Voltage Doublers worked and your video showed me how. Is there are rules of thumb for how much current one can get out of the circuit based on the peak or RMS current of the transformer? Thanx! Gordon

[AllAmericanFiveRadio]

The voltage potential outputs from these circuits are 100% dependent on charging capacitors. They do filter but that is secondary. These circuits are deigned for high voltage and low current use. So everything is dependent the capacitance of the capacitors and how fast they can be charged. This is not the type of power supply you would use if you need a high current output.

[coolbluelights]

Excellent demonstration! reminds me of AC theory back in school!

[AllAmericanFiveRadio]

Thanks Dan.

[Maxxarcade]

Great explanation!

Is there any disadvantage to using a voltage doubler vs. a normal full wave power supply? I was under the impression that voltage doublers were used in some tube amps because a cheaper power transformer could be used, but I know there are many other applications too.

[AllAmericanFiveRadio]

Thanks.

Voltage doublers / multipliers are used in circuits that require a high potential but low current. And they are very economical circuits to build to supply this requirement. One example I have of where they are used is in my Heathkit Laser. It needs a high voltage but low current potential to get the Helium Neon Laser tube to function, to laze.

[demios99]

Excellent explanation, very straightforward and clear. It helped me understand basic voltage doublers and more complex CW multipliers. 5*

[AllAmericanFiveRadio]

Yes, yes, yes, a strong understanding of the basics is most important. With that you will be able to understand much more complex circuits. Thanks.

[jenko701]

I have been in electronics for over 25 years .You explain things better the any teacher I have ever had.

[AllAmericanFiveRadio]

Thanks, thanks, thanks.

[jimbobg65]

Thanks very much for all your videos. They're helping me a lot with my understanding of circuits.

[AllAmericanFiveRadio]

I found these circuits interesting and very useful too. It was a challenge making the drawings, but fun too. Thanks.

[Barnekkid]

That was very clear and easy to understand.

[AllAmericanFiveRadio]

Thanks. I enjoyed making the drawings for this, 42 I think. This was a fun circuit to think about and put together.
