Voltage Doubler - I Already Made It Better! - More Power And Stability - Simply Put

This is an improved version of the 555 timer based square wave fed voltage doubler from the previous video, that can drive a larger load while remaining more stable and losing less voltage, and also power amplifies the square wave with a push pull BJT pair so that the actual timer chip is not bearing any of the load, and thus any square wave source at all, no matter how weak, could drive the circuit.

Hello, I have follow you advice to make de circuit and these are the results.. 8.4v, 326.7 Ohm load, 25mA. drive.google.com/open?id=1YcIVwT4CfpnYd6Ie1MziF1fPHIaLBKcU here some pictures

[@scottybadmoon3857]

I got some freebies from neighbor, tons of ceramics. Caps, whole 9 yards really. found a few 555s, even a dual 556. Got 4 double a's. 6v to 9 on first successful build. Considering stacking 555 timers. So this vid is very helpful. Thank you.

I've read your take on simulators on the other comment, but a simulation in Ltspice with ideal components shows the diodes are incredibly stressed from the point of view of the current required from them in the first cycles since startup. Currents skyrockets in the kA range. And even with a 50 ohms series resistance in the pulse generator and 1 ohm internal resistance in the 5v battery I get several amps in the diodes. Of course in a real setup current will be limited by the source compliance and probably by the ESR of the caps, but doesn't this current surge tendency point out that this design could be failure prone? Edit: I have used pretty steep rise and fall times in my simulation - about 20 ns - to emulate my siggen. Surely a 555 will produce a far more trapezoidal pulse train.

Dude, that's cool. Kind of beautifully simple. Cheers

Pwm from Arduino, feedback on an analog pin after a voltage divider, and duty cycle aiming at a target voltage! That sounds fun!

Please c 6:30 omponents required for 56 v dc from 12 v dc

I love Your video's, but You cut it very fast- You should do it without cutting!

So what would be appropriate to use at the base of a volcano? Lol! :)

[@videosforthegoodlife2253]

Probably a fraction of what would be appropriate at the emitter of the volcano.

Hello, I started to simulate the circuits using the proteus program and I have achieved 7.4V with a load resistance of 70 Ohms thus getting 105mA. I don't know if the simulation is correct. Is there a way to share the file and that you can review it? Thank you.

[@simplyput2796]

I don't have experience with simulators really, and they're notorious for being inaccurate in funny ways to reality, so I honestly couldn't tell you. My advice would be to just build the circuit and see what you get, since it uses only simple basic parts.

Thank you for content

[@keithking1985]

so you just used diodes instead of BJT's awesome, would you be getting more energy out because bjt's use more when in use?? what i mean is the current needed for the bjt's is giving you more energy with the diode's so you get more over all power out??

[@simplyput2796]

I don't understand what you mean? The diodes are part of the doubler, and I am using BJTs (one NPN and one PNP) to push-pull power amplify the square wave, meaning that the timer chip (or arduino PWM pin, or whatever) is only driving the BJT base current, and the power source is providing the rest.

[@keithking1985]

@@simplyput2796 oh right i thought you removed the bjt's in favor of the diodes.. my mistake.. sure i forgot you about the square wave as the signal. but still a very cool video, its something i will defiantly use in the future..

[@ThaboW11]

You are absolutely incredible! Keep on keeping on!

great explanation as usual, thank you.
