In this video you will find some examples on how to make your own buck converter circuit using the P-MOS IRF4905 but also the IRFZ44N N-MOS. Also you will learn why do we need all those components. You can find all the links for schematics/codes below. I hope that you'll enjoy the video. Stay tuned for the BOOST converter tutorial.

This is the best tutorial I've heard on buck converters, I actually understand now. Thank you, I subscribed.

@roseelectronics4582 3 года назад

It's also very nicely explained by Adamant IT.

@pietervheerden 5 лет назад

I love the way in which you break things down. Imparts knowledge in stead of just information... and extremely helpful for someone like myself who's trying to learn electronics.

@chaddd41 5 лет назад

Great video editing. You're very good at explaining things in a clear, concise manner that isn't too technical, yet still informative.

I really appreciate your video. So many idiots on the internet explaining buck converters and feedbacks in such a confusing way. Yes you can just buy the LMxxxx, but I love the way you explain the DIY version, so that using an LMxxxx is just another step up. Very nice.

@erikderuiter7475 2 года назад

Wow... Your explanation is so good! Exceptional... I'm learning about power supplies for Nixie tubes and your information is invaluable. I only wonder about safety of for example a NE555 based PS. Dedicated IC's have protection circuitry but I read that the often used Maxim 1771 has a poor design because the gate of the Mosfet is pulled to ground by a resistor: quote "a substantiol amount of power is wasted in the FET" But I need to look into that much more... I want a safe PS so I can leave a home made HV PS safely on 24/7.

@tomgeorge3726 6 лет назад

Hi, a schottky diode is used because it is a high speed switching diode, compared with a 1N4001 series diode. High speed because of the switching speed of the converter output.

@freddofrog1357 3 года назад

Good video, well explained. Maybe a brief explanation of the application of the fet and bjt would complete an otherwise very informative tutorial.

@maotradok3790 5 лет назад

@Electronoobs can you make a tutorial of calculating the parameter of the component of each of the converter? that should help me a lot

@yogendrakahane9455 6 лет назад

Consider an electrolisys aplication. The plates and electrolyte form a capacitor. In the begining, the electrolyte is cold and conducts less requiring higher voltage to push current through. Then as the electrolyte warms it becomes less resistive and conducts more current. Annunregulated buck converter dops in voltage with a higher current draw. And with electrolisys, lower voltage end up drawing less current and produces hydrogen more efficently. The current voltage responce us more like a zener diode and resistor than a simple resistor. This loosely uses current to warm up the electrolyte making it more conductive so that it can pull more a little more current at a lower more efficent HHO generating voltage. It loosly self regulates the current without feedback circuitry. An adjusable pwm circuit can may be more interested in lowing the duty cycle with feedback from a temperature sensor to further regulate how much current goes through the cell by lowering the outut voltage further, thus controlling the watts consumed by the HHO cell and further improve efficency.

@Graham1904 4 года назад

Great video, super advice on technical aspects. What PWM frequency did you use on your own switching circuit? I couldn't read your scope you were moving so quickly :)

@siddhat7802 4 года назад

How did you calculate the inductor and capacitor values. Also, what factors did you take into consideration while calculating those values? Finally, how did you select the switching frequency to turn on and off the Mosfet?

@arunajain4218 6 лет назад

please make a tutorial for DC motor drone! waiting it for a long time ! please make it

@jakenbaked87 5 лет назад

When is the best time to use an optocoupler for feedback? How do you get around frequency limitations for high frequency optocouplers?

@miguelcolon4690 4 года назад

Excellent!!!!! Liked to know how to change a 40vdc battery trimmer to a wired one. 110vac. A boost switch? How it works?

@samk2630 5 лет назад

This has been very informative, thank you for producing such great content. Is there anyway to calculate what resistor you would need if you didn't want to use a pot? Ex. 12v DC input, limited to 7.5v DC output?

@RoyAndrews82 3 года назад

The inductor has a current charge rate.. The capacitor has voltage charge rate.. Together, if you know how to sense voltage discharging edge triggering, you can choose when to charge the cap n inductor.

Hey electronoobs. Unas preguntas. Que has estudiado para saber tanto de electronica? Que libros, webs, videos de yutuf recomiendas para alguien que se quiera meter? Que proyecto de los de tu canal es el que mas te ha gustado? Y que proyecto crees que esta bien para alguien que no tiene mucha idea?

@ELECTRONOOBS 6 лет назад

He estudiado ingeniería electrónica. Recomiendo mirar tutoriales de RU-vid y probar todo emepezando con pequeños circuitos como este. Recomiendo que te compres un Arduino y hacer pequeños tests. Como libro te recomneido Basic Electronics de Walter Banzhaf. Saludos!
