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]

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.

at 6:55 i think that résistors 1k and 8k should be flipped , they are placed wrongly i guess, arduino will see 44.4V at its pin in this case, considering the max output voltage to be 50V. Thank you for this great tutorial !!

[@samannosheen7875]

Excellent tutorial on boost converter

[@aleksandarjakimov6830]

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]

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

[@aleksandarjakimov6830]

@@ELECTRONOOBS yes, just need to flip resistors. Thank you for your videos, you do awesome job. I'm really glad that there is someone who explain things awesomely, so that everyone understand.

Hi can u please tell the number of turns in the toroidal core? I need that formula asap for my project...please reply asap😢

[@youcan4913]

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.

[@hamadyt956]

That value depend upon input and output you have to calculate our

[@holy2090]

@@hamadyt956 the measured voltage should be at the side of 1k resistnace, but the schematic diagram show that the voltage is measured at the side of 8k resistance... So measured voltage can be easily larger than 5V...

Great video. How did you calculate the values for the inductor and capacitor? What factors did you take in consideration while calculating those values?

[@elChico-TV]

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]

hmm, I'll make some research on that!

[@FuchsHorst]

Electronoobs yes, please do it.

[@a1nelson]

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?

[@FreeCircuitLab]

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

Can you make a powerbank (stupid question) But this time Arduino as a controller So we can use a oled to see how much power is left,how much we used, charging stetus and which port we are using on what ampere (1A , 2.1A) And Arduino will control the MOSFETs of booost converters And a small button for torch light like other display powerbank modules This will be a great project

[@John_Smile]

Could you build a Boost Converter with current adjustment, not just voltage ajust? Also, I would like an output current greater than 1 A. Maybe 3-5 A would be OK.

[@devilvortex1]

Maybe better using a optocoupler to the arduino for the feedback control.

[@eddiemolina657]

What the voltage value of your input capacitors. Plz have a detailed values on your capacitors. Thanks😁

[@fallen546]

If I put my microcontroller in deep sleep and the load drops to a very low level, will the boost converter still eat through the battery?

[@gamerpaddy]

what does the final output voltage range depend on? bigger coil with more henries or higher frequency?

[@AbsoluteTrash_]

larger value inductor is the main variable that effects Vout

[@seckinseckin3919]

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 ?

[@neail5466]

What will happen if the frequency of the pwm is altered?? Does the width is referred as the dutycycle?? Iam little confused...i have used the pwm for certain application but dont know which one is referred as the dutycycle? As always excellent explanation...can you take the time to explain popular xl4015e1 ic used in ready-made buck boosts,, Is the arduino be replaced by a 555 along with mosfet driver (if necessary) Why commercial buck boosts doesnt comes in 1 body, is it not possible to built one in the same body? I Know too many questions...😂

[@AbsoluteTrash_]

it is technically possible to build them within the same body, but since the inductor is having to support the entire load you will end up with a much lower tolerance for higher current applications. A higher frequency signal will result in better stability, but if you want to supply more power the inductor needs to have established as big of magnetic field as it can, which takes time due to the nature of inductors, so if the frequency is too high the inductor wont have time to reach full capacity. The duty cycle of a pwm signal refers to how much of the time during each cycle the voltage is high, on an oscilloscope this is seen as the width of each pulse. While you can replace the arduino with a 555, you still have to control the duty cycle to maintain a steady voltage, im not quite sure how you would go about controlling the duty cycle of a 555 while maintaining frequency and using the direct output from it to control the switching. But you can just use it as an oscillator for the circuit, and use extra circuitry to change the static square wave into a dynamic square wave with varying duty cycle.

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

[@bitsurfer0101]

How do we determine the maximum voltage that we could attain from the boost converter?

[@phasehalide]

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.

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.

[@werner7156]

I built the circuit without a driver transistor and controlled the FET directly ( IRF1404), the circuit did not work at all at first, I had to slowly turn up the potentiometer on A0 so that the capacitor gets charged stepwaise , otherwise the gate of the FET was switched ON way too long and drew 7 A constant without really working . The control behavior only worked as long as the capacitor was not suddenly discharged, the problem is the gate time, 01.254 is set in the program, that was way too high for my circuit, only when I had reduced to 01.220 did the circuit start immediately even if the capacitor suddenly started was discharged with a short before. I am currently building a device with which I can spark weld nickel and steel wire (for vaping) and I need up to 120V depending on the diameter of the wire. But I also want to intrude different functions, so I reach for the Ardurino. With the PWM I only realize the precharging of the capacitors, but I also want to determine which power is charged and after which time the circuit on the capacitor to the welding contacts is interrupted. With the new PWM setting, I now fully charge 3 parallel capacitors 200V 470uf in 2 sek. I also donated a Z diode with 4.7 volts to A1 for Protaction. It is still a lot of work to do because I am just a hobby electronics technician and the last time that i programmed I using Power Basic (about 25 years ago ) :-))............
