Wonderful
Sir you way of teaching awesome.sir agar 5v mobile charger ko veritable banana ho aur us main tl431 na ho tu kia karain. Thanx
TL431 nahi hai to zener laga hoga 5.1v ka. Zener ki value change kar ke fix voltage change kar sakte ho, variable nahi hoga. Variable ke liye TL431 chahiye...❤️👍
❤❤
V. Good sir
Thank you brother ❤️👍
Very nice awesome video.Thanks to provide precious knowledge.
Thanks and welcome brother ❤️👍
Very informative video.Sir Output voltage ka Range kitna hoga?Thankyou
Agle videos me bataya hua hai dost ❤️👍
Sir very good and nice..
Apne samjhane ka haq ada kya hai
Shukriya Dost ❤️👍
Excellent video ❤
Sir output capacitor blast hoga jab usase jyada voltage badhayenge to mai samza nahi ki output me trimer pot se jab voltage badhayenge tab capacitor ka calculation kya hai
Seedhi baat ye hai ki, output par Jo bhi voltage aap set karna chahte hain, aapka output capacitor usse adhik voltage ka hona chahiye warna wo fatt jayega.
Ampere up down kaise karen sir
Very 👍
Thanks ❤️👍
great
Thanks 👍
Nice video
Thanks brother 👍
nice video
Thanks brother ❤️👍
Sir kindly ups inverter ki completely video banai plz taky repairing krna easy ho
OK, jaldi hi banaunga 👍
Waiting plz
😊 good
Thanks brother ❤️👍
Sir pfc power supply ke bare me bhi kuch bataye please
Thoda samay do dost, PFC bhi meri list me hai 👍
Sir ji transister c2383 ka smps suply me work pratical batai input section me
Sir 5 volt se km ap ne jo practical is main thori boht output main variation hy..
For example 4.46...4.47...4.48.....4.49....phir 4.46 etc.. Aisa q... Kia koi msla hoga .. Suply sahi se work kry ge kia load condition main?
Sahi kaam karegi dost bus aap voltage Kam jyada karte samay load connect kar ke rakkhen jaisa ki maine video number 37 me bataya hai. Aur voltage utna hi Kam karen jahan tak wo stable hon, agar fluctuate hon toh usko thoda bada len🙏
❤❤❤🎉🎉🎉😅
Sir smps को अपने हिसाब volt aur एम्पीयर के लिए कैसे बनाएं कि singl supply, dual supply हाई वोल्ट जैसे 30.0.30 volt 10Amp 15Amp, 25.0.25volt में

Bhai mne bhi ye potentiometer lgaya tha ase hi kr k to ab output voltage 3 volt aa rha hai kse thik hogi pls help me
TL431 ki pin1 aur ground ke beech Jo resistance lagi hai wo badal do, problem theek ho jayegi..
सर smps को अपने हिसाब से कैसे design करेंगे कि हमे kitane वोल्ट और kitana एम्पीयर लेना है
इसके लिये क्या मोडिफाइड करना पड़ेगा
इसकी बात आने वाले वीडियो में करेंगे दोस्त ❤️👍
Sir 12volt chargar ki badakar 14volt karne ke liye video banao
Video number 30 aur 31 me aapko bata diya hai ki resistance ki value kaise nikalni hai. Ussi tarah se value nikal kar aap resistance ko badal do, toh output par 14v mil jayenge. Jab Tak aap khud nahi karenge, toh seekhenge kaise ? Phir to mere video banane ka bhi koi matlab nahi reh jata dost. Mai aapko sikha kar atmanirbhar banana chahta hu, taaki aapko kisi se bhi poochna na pade. Mere se bhi nahi. Pehle aap try to karen. Nahi hoga toh tab mai toh bataunga hi na... Please ek baar pehle khud try karen 🙏
Sir ji aapne bilkul sahi kaha hai
sir ji 5volt ki smps ka output capasitor change kar ke highiest kitne vot tak badha sakte hain. ya transformer bhi change karna pad sakta hai.🙏
Capacitor change karne se voltage nahi badte dost....
@@vccground-hindi mera matlab tha sir jo aap voltage divider ki value change kar ke jo aap bata rahe the..🙏
iss ka answer mujhe aapki iss se agli video me mil gaya hai ...thank you so much sir🙏🙏🙏
Sir mere pas china bettrey charger hai 20amp ka 14vlt pe kam karta hai output capister 35volt 2200uf laga howa hai us pe output 50 k lg bag volt aarahe hain us ko ye vr laga k wapis 14 volt kar sakte hain ya nahi?plz reply
Kar sakte hain 👍
@@vccground-hindi Thank u sir
@@vccground-hindi Thank u sir
Sir ji suply ko kitne limit tak bada sakte hai batai
Ye koi fix nahi hota dost. Ye sab uske PWM IC par depend karta hai. Aapko karke dekhna padega...
If we change the output, power will remain same?
Yes, almost.
Aslamoalakum Bhai kea Haal hein kesy sub ok
Bhai ye Jo 24volt smps supply he is mein koi 24-0-24 volt 220 ac per chaly ka koi sercuit diagram aap ke paas ho to please send kar dein aap ka buht buht shukrea ho ga
24-0-24 bana kar kya karoge aap ?
@@vccground-hindi aslamoalakum gee Bhai kesy hein. Double supply amplifier mein lgani he
Sir video no 30ma jo resistor ki calculation ap ne samjaya ha is circuit ma R1 or R2 ki value different ha. R1=10 k R2=9.5 q? 5÷0.005=1000 ohm total resistance banta ha plz Sir ye kia ha
Iss circuit ke designer ne feedback current ko bahut hi Kam karne ke liye resistor ki value jyada lagai hai...
@@vccground-hindi thank you sir
Sir, if we increase or decrease voltage then what will be effect of ampere?
Amperes are inversely proportional to the output voltage. If you increase voltage, amperes will decrease and vice versa...
Sir 12v power supply me 10k+10k Hai to voltage badhane me hoga, but manlo k
12/2.5×10-10 = 38k Hota Hai
Plz explain
12v ki supply me dono resistor ka value same nahi ho sakta dost. Dubara check karo 🙏
@@mukeshvora7701 ye toh sahi hai 👍

Sir thanks for this video Practical Feedback Circuit Modification in SMPS , i have a question , i have a branded mobile charger 5v with 3A .... i am facing a problem .. mobile is not being charged b/c in o/p section 4.84v shown... , there are three o/p capacitor in o/p section 25v 330uf and TL431 zener diod and OPTOCOUPLER are being used.i have checked all capacitors are goods and also voltage divider resister 220 ohms also shown correct ohms but i am unable to understand where is problem.. i.e where need to be checked ... i am waiting your reply thanks again... i am getting 4.84v but i need 4.9v or 5v ...... where is droping voltage...
Check both resistors value of the feedback voltage divider. You have only mentioned one resistor value of 220 ohms...What other resistor value is ?
@@vccground-hindi both divider resister value is 22 ohms
@@husssainali No brother, it can not be 22 ohms. Please recheck...
@@vccground-hindi both have same values

But if we increase the voltage it decrease the ampaire. ( current).
Exactly. My next video is on the same topic 👍
agar menvali tonar lagake kantol kare to
Kar sakte ho dost ❤️👍
Sir what is c5 in this circuit below pc817 optocoupler?
It's the high frequency suppress capacitor that connects between primary and secondary grounds. It's main function is to ground the high frequency ripples produced by various output loads .. 👍
@@vccground-hindi helped alot thankyou
Very nice sir once again you are genoius and great teacher aisa k jo apna elm chupata nahi..
Sir kya es trimmer k jaga simple 10k ya 50k volume type potentio use nahi karsakte agar nahi tu kun?
Transformer primary connection
Kya matlab...?
Wiring diagram bhejiye, isime sm transformer ka connection nahi pata lag raha hei, primary side...
@@gananathmaharana1763 Dost isme Maine aapko feedback section ke baare me hi bataya hai. Primary winding ke connection nahi bataye. Phir bhi aapko circuit diagram chahiye to DTH supply likh kar Google karenge toh mil jayega aapko ❤️👍
Sir jee amp Kitna rahega Apne bataya NAHI
Voltage badayenge to Amp kam hoga. Voltage kam karenge to Amp bad jayega dost ❤️👍

how to calculate load (watt) ?
Voltage x Current = Power
