The Simplest Voltage Booster? - Charge Pumps Tutorial

[@anoimo9013]

On diagram 3:00 technically you could getaway with polarized capacitors, but if the load is low impedance or a short, they can be exposed to alternate current. Unless there's an extra diode

[@zaneenaz4962]

Really enjoyed this video in which you show your evolution in implementing V-boosts. Dealing with power systems (solar) has intrigued me with using boost circuits to draw more power from my small solar array. Ignoring the subtleties of charging modes, a low battery can actually double the current flow, balancing out the power flow for changes in irradiance, as well as a few other tricks can cause a meaningful boost to the energy captured. Inductors are simpler than capacitors and less prone to failure.....they are great storage devices.

thanks dude. this was the video i needed on charge pumps. your initial demonstration at the beginning was just the right thing to show for this to make sense.

[@davadoff]

5:41 No, that is 20v out with ideal diodes, not 15v. The third cap = 15v with CLK low 6:21; then when CLK goes high add 5v = 20v out.

Better is to multiply ac than us for DC. To multiply DC you need more clocks means more connection of voltage. Depends upon where we need multiplication.

Thank you your comprehensive video tutorial on how charge pumps and boost converters work, and the disadvantages of each type of DC-DC voltage boost cct. You have covered numerous important considerations in circuit design. Great job!

[@SineLab]

Thank you for watching! :)

7:52 Why "a couple hundred milliamps"? Why not more?

[@johnaweiss]

1:32 "The voltage drop in the loudest place across it." What?

[@xzddakfdmiug5832]

It seems counterintuitive to be able to boost voltage. Maybe it is a bit like increasing the PSI of the flow of water by changing the diameter of a pipe. In any case, thanks for making another great video.

[@citratune7830]

Not really though because when you make the pipe thinner the thick part gets the higher pressure

[@jonnycash9688]

Its exactly that, PSI = voltage, Flow = Power (W)

[@Bruhwhatthesigmaohio]

Could you please tell me what component model specs you used? Like the type of capacitors,diode. And what is the max current that can generate?

[@wherami]

That’s exactly what I needed for a project I just built that is very low amps but needs 12 volts

[@SineLab]

It's the perfect circuit for that situation! :)

[@johnaweiss]

5:17 Why is it "better" to avoid virtual grounds and intermediate AC signals?

[@eboy536]

How much current available this circuit?

[@PraxZimmerman]

Impractical, unless that is you have a functionally limitless supply of 350v 130,000uf electrolytic capacitors.

[@Mosinsarmory]

I have like at least 2000 different capacitors of different sizes in my kit

[@avejst]

And Then there are the charge pump, that make use of mos switches to make 5V to +/÷ 10V in the Maxim patent, used in the MAX232

[@Inti72600]

Hey thanks a lot for this video,i've looked online for some useful charge pump circuits and came across some of the ones you showed, but the last one is by far the most practical one, despite it not being able to deliver much current.

[@SineLab]

I agree, just keep the current to a minimum. :)

[@anexoworkshop]

Could chage pumps be used as a circuit to verify if voltage transducers are reading voltage correctly? 300VDC transducer.

[@thecheapaudioengineer]

I used charge pump for my class A power amp i had built years ago... To boost the voltage for pre amp part..

[@muhammadhassanulhaq]

Wow, I mean Great 👍. Finally someone speaking in favour of voltage multipliers. I have used them to create negative rail voltage for operational amplifiers

[@shawncalderon4950]

I am so glad I found this channel! Great explanation! You have a gift for making complicated topics simple to understand.

[@SineLab]

Thank you! It's good to hear that my videos are helpful. :)

[@domdom1941]

Great Video☝️

[@SineLab]

Thank you :)

[@incxxxx]

OK. Nice!. But you definitely have to improve your diction, because is very poor.

[@ivanpiro999]

The step by step explanation of the Dickson pump is brilliant, it shows very clearly how the capacitors sort of "bucket brigade" their charge along the circuit
