I made a very similar video last week but it will not be released for months. What a coincidence. I used a breadboard and then soldered the circuit. I enjoy your videos and learn alot. Thank you.
Really helpful sir. Yesterday i tried my self to increase the voltage of 12v adaptor to 15v. So i tried alter the divider point of tl431.So i used the following fomula to find the divider resistance value. =2.5×(1+R1÷R2) here R1=51k and R2=10k. so the output is 15.25v. And my output voltage is also as expected sir. My doubt is. Is it make a pulse to control the optocoupler or its just turn on the led sir. When ever i have a doubt about a specific topic, your also make video in same topic sir☺☺Thank you once again.
great you also need to change the current limit ratio with the same ratio if you increasing 12 volt to 15 volt and you are adjusting reference resistor network then the output voltage will increase in output of the TL431. which will cause to increase the optocouper LED current and it will also disturb the feedback so you need to increase the current limit resistor to decrease the LED current so the circuit will work without creating ripples or ringing in swithcing
@@HaseebElectronics wow great sir. To understand your comment I read it 3 Time. Now I understand. The led current limit resistor value is already 2.2k . So I thought it would handle the led current. Thank you for your valuable comment sir. It makes some sense to me.
Without confuse sir again i request if two ic is connected in circuit board where is the returning path of current flow.please explain sir the returning path of current in ac and DC circuit.
Willkommen, Bruder. Ja, du hast recht. Wir müssen präzise Widerstände mit der geringsten Toleranz verwenden. Aber da es nur eine Demonstration war, habe ich gewöhnliche Widerstände verwendet, um einen Spannungsteiler zu bauen. الله يسلمك ويسعدك
Hocam bize şarjlı matkaplarda şarjı kesecek yeşil ve kırmızı renge dönüşecek bir şarj devresi kurabilirmisiniz.Mesela 3 pilli şarj eden devre 12.6v şarj dolduğunda kessin.
Sir Goldstar 9500 satellite receiver has no output vcc cap and switching ic have unstable voltage 2R2 2R4 and 5R1 resisters gives continuity is it normal? thankyou
I'm from Sri Lanka sir that I request regarding clamp meter circuit diagram and working system how could fault finding the defective clamp circuit and rectify could you please explain thanks

wow that is awesome. i will wait for that video
humble thanks for your valuable encouraging words.
Thank you for clearly showing and explaining this electronic component . All your lessons are fantastic . My knowledge has greatly increased .
Always the best teacher in youtube electronics❤
Every video of yours is amazing.
Very informative vedeo. Thank you so much. God bless you.
it is my pleasure
Thanks brother for your knowledge and education
it is my pleasure
Great video sir. Thanks! 🎉
You are most welcome.
Great Videos as always. Thank you. Hasseeb.
Great video!
Nice sir👌👍

Thank You! Very detailed and clear.
You are welcome!
Thanks sir for everything 🙏.. really thanks
Haseeb top G!
Awesome. Thank you sir. Please sir explain how to programing MCU.
Great! Thanks and have a nice day!
New assalam walekum new friend like done❤❤❤❤❤❤
What a man!!! Not teaching much better in college practically...power electronics...keep it up sir...i learned more from you.❤❤❤
So nice of you
👍👍👍👍
Mobile charger 4.2v 800ma . Can i use resistor at the output to get less current, up to 300ma?
you can increase current sense resistor at MOSFET source pin to limit primary current
so the output current will reduce
Much appreciations sir👌👋
Thank you 🎉🎉🎉
You’re welcome 😊

Battery negative terminal is most of time reference point
Ich schaue mir gern deine Videos
Beim Spannungsteiler sollte man präzise Widerstände benutzen

Hello sir , can you explain how to identify high frequency transformer and how to find replacement / on the transformer 2020-X41 /

Why is TL431 too difficult for me to understand?
yes. it is somewhat is difficult but interesting
hi sir where is your office located
i am in Jordan
Your old vid about TL431 was stonishing ,but this time 🤔 not so good .
Salam lebst du in Deutschland
wa alaikum salaam. ich komme aus Pakistan und bin jetzt in Jordanien
Salam أخي ich Versuche ein be quiet straight Power 11 zu reparieren ich habe den Verdacht dass die PFC defekt ist@@HaseebElectronics
