I hopt that you enjoy this basic tutorial on switched boost voltage regulators. Want to help my projects: www.patreon.com/ELECTRONOOBS Thank you very much!

@sadecemuhendiss 6 лет назад

Electronoobs could you implement a PID controller for the feedback to minimize the jitter of the PWM signal? So everyone can see how a PID controller can done easily.

@elChico-TV 6 лет назад

What about making video where you can "hack" one of this buck boost converter to be controlled by arduino using their feedback pin i tried once i think it was 1.25v if voltage is higher output voltage goes lower and if its lower the output voltage goes lower too.. and does this will affect to output noise / ripple ? Thanks

@ELECTRONOOBS 6 лет назад

hmm, I'll make some research on that!

@FuchsHorst 4 года назад

Electronoobs yes, please do it.

@a1nelson 2 года назад

Are you perhaps referring to the use of a linear regulator, such as the LM317? There are lots of 1.25V hacks with that part and ones similar to it. With a switching converter, the feedback works differently and doesn’t rely on a linear regulator for feedback. In fact, since the feedback/control is closed loop (as shown in the video), the linear wouldn’t be particularly useful, unless it’s being used as a low-cost, voltage reference. As a side note, although it’s not effective at reducing ripple as people seem to believe, it’s nevertheless common to use a linear regulator to _help_ filter the output of a switching converter. Of course, this requires the switching circuit’s feedback to compensate for the linear’s dropout as well, above the desired output voltage. Does that help, or am I not fully understanding your question?

If we have 12V and 1Amp(fixed maximum) and we boost it to 48V then what maximum Amps we will get from 48 volts?

@seckinseckin3919 3 года назад

One question . I put one coil between wires and increased frequency with frequency generator.. when i adjust higher frequency in multimeter i saw voltage becomes lower so that means it is inductive reactance decreases this voltage. In boost converters when you increase the frequency then voltage also increases because diode and capacitor prevents this reverse polarity phenomena (inductive reactance).. so switchin coil without any components makes voltage drops but switchin coil with diode and capacitor you can keep voltage higher.. am i right ?

@FreeCircuitLab 3 года назад

Hi, sir! I am trying to make a boost converter for 4v to 12v using 555ic. I made the circuit and it works fine but I can't get current over 200mA, no Matter what I do, I have tried different inductors from CFL ballast, then made my own inductor 20turns 4x parallel wires in a cfl inductor core, then tried a switching transformer primary, then made a toroidal inductor but at the best case, 50ohm load can be connected while getting 12v but the efficiency became 50% at this situation, otherwise it remains around 80%. I did a long experiment of trial and error, tried different frequencies (upto70KHz), different dutycycle, nothing worked, the max wattage was 2.5W only. I didn't make feedback because I will drive constant load as LED and with constant input voltage too. Now my question is, is it possible to make this more powerful, I tried my all knowledge, now I need your brain... Can you help me? I also have a feedback plan for 555, just to use an optocoupler to pull its reset pin down while the desired voltage generates, the LED side of the coupler can be drived by a zener diode or TL431 for voltage setting

@phasehalide 5 лет назад

That 2K resistor from the gate to Positive input before the inductor has me baffled a bit because it seems to be puling the gate of the mosfet high which will turn the mosfet on as soon as power is applied to the input essentially making the mosfet short out the possitive and negative rail constantly unless the arduino interupts it. so if the arduino is not running for some reason the whole thing ends up in smoke. Reason i am asking this is because i am building this circuit right now and have nearly completed it but i don't want to apply power to my PCB before i have this query answered please.

How much output from your boost converter? And How much input for this circuit

@christianacar2745 4 года назад

Hi Ive done this tutorial., I got one problem., When I put resistor to the output, the voltage goes all the way to 2V thats the reason why I cant build the feedback which consists of voltage divider.. pls help

@aleksandarjakimov6830 4 года назад

At 6:20 pop up message state that voltage divider output should always be under 5V. At 6:55 schematic shows that 8k ohm resistor is to the ground and 1k ohm to the output from boost converter. You took output of voltage divider and set it to A1. With voltage divider formula 8k/(8k+1k)*output, you will be way above 5v. Example: if we want 20v at boost converter output, output of voltage divider will be 8k/(8k+1k)*20v, and that will be 17.78v. You just need to flip resistors, 8k to output of boost converter and 1k to ground.

@ELECTRONOOBS 4 года назад

I think the schematic has a small mistake. It should be reversed, 1k/1k+8k so a divider of 1/9

@aleksandarjakimov6830 4 года назад

@youcan4913 6 лет назад

Great explaination. In schmetic diagram of close control please interchange the 8k and 1k resistance otherwise the output reference which is feedback to Arduino will be greater than 5v.

@holy2090 Год назад

@urgirlcassie23 5 лет назад

Would this 600V Schottky diode (1N5406) work? I want to build a high voltage boost converter controlled by Arduino (the goal is to be able to throttle the voltage of an extremely high voltage Cockcroft-Walton from 5-100% without any knob-turning - no potentiometers, no variacs, etc; software only, controlled by an RC transmitter or other wireless signal). Are there any issues you foresee in building this modified boost converter circuit? Obviously, I need a larger voltage divider. How will I need to change the inductor, cap, etc. Maybe I need to use an optocoupler or something to protect the Arduino? Any tip/advice is appreciated.

@rolandberendonck3900 4 года назад

Nice Idea to use An RC control to be safe when you want to change the voltage 👍 Great Idea! Obviously you need a flyback without a diode charging your multiplier and not Just An inductor.
