Vary.nice.sir
Nicely explained. No body can't explain such a way. Thank u so much. God bless you.
Very valuable information thanks to you
best regards and special thanks
good. can you please make a block diagram of this like the series on solar inverter. that was extremely valuable series.
as most things include power supplies so making a block diagram series of power supply will be very helpful.
nice channel mashallah keep it up sir
Masha Allah
best regards
Nice video sir
Good information sir

Well done sir, mashah allah
thanks a lot dear brother
Aoa sir main regularly ap ki videos daikta hon or bhot kuch seek rha hon in videos sy thank you so much jazak ALLAH ap ny aik video main kha tha k ic ki switching chk krny k lye mosfet k drain to source voltage chk krein agr voltage main capacitor sy zyada hein tu switching ho rehi hy werna nai
Lakin mary pas aik charger hy jis k main capacitor k voltage or mosfet k drain to source voltage same hein mgr charger phr b work kr rha hy is ki kya waja ho sakti hy?
Good Sir
Thank you sir

Hi sir very nice video
Sir qawa kha mal skata hy...
12v to 40.0.40 Tl494 Dc to dc conveter pe ek video banao car amplifier ke liye.with voltage feed back and current feedback jo
sir ap ka taareeqa bohot acha hy sumjhane ka mgr ap kahein kahein thora sa raaz cutt kr jaty hain is liye thari si mushqil hoti hy
or ap mery comment ka reply or us pr video nahi benatay 😔
Hi
Sir
Apa inverter a.c ke bare me kido banavo na
Indoor ane outdoor k all section par
Sir ji PFC supply me explain karye and utl Charger
Excellent. Sir mere paas 2 computer power supply he donoo k 12 volt nahi aa rahe. jab Optocoupler ko short kare to yellow cable per 9 volt aa rahe he. is tarah 5 aur 3 voltages b kam aa rahe he. Is me kia masla ho sakta he. please is per aik video banay. Thanks
Salam haseeb bhai ic lm393 ko explain kary mehrabani kar k
Thanks Haseeb bahi for the video mara aik sawal ha 12v Smp power supply k DC output 0 ha or DC output positive or negative multimeter pa beep data ha kaya issue ho ga
Haseeb Bhai aap bar bar kahten hai ki koi bhi suply uda to ye pata karna chahiye ki kyo uda kya rasistens ke 2.2 OMS ke open ki wajah se Transistor uda hai.
Salam sir
Sir what will happen if we use a Mosfet instead of transistors in this supply will it work or will it damage the other components.
Sir ji, inverter compressor chalane k liye ek circuit banaye, Jo manually ho
Thank you sir...
If SMPS get late on what will be prob...?
Sir is suply ko 12 volt sy brha kr 72 volt tk kr sakty Hain???
Sir ji smps zebronic cu5013 mini inverter board ka ek video banao
Aghar D13009 nahe Hy tu is ke jagh Konsa use kar sakty Hy plz reply dear brother
Haseeb Bhai slamwalekum. Mai Dimand join karna chahta hu.mujhe aap jaisa smart Banna hai . Mai aapse bahut kuch shikha hu .par mai smart electrician nahi ban pa raha hu. Jab koi nayi circuit repair ke liye Mita hai tab mai bareek fantion ko samajh nahi pata hu. kya mujhe sabhi iç comments ke data ko bar bar ratna chahiye. Mera help kijiye please Bhai.
Mashallah
lk nice

Sir mosfiet aur rictifieyar ki pehchan ic me pasitiv aur grawan kaisey malcom karny
Assalamu elakum Ashraf Bhai.
Agar switching IC damage ho Jaye to MOSFET kharab honay Kay kitnay chances hotay Hain
Please also clarify that if switching IC fails then what is the status of MOSFET Gate is it in on condition or off condition.
Thanks and regards. Naseem Ur Rehman.
hello how can i download that schematic diagram ? Thank you ..Great video
Hello sir, could you please tell us what is the difference between filters, snubbers and resonant converters?
Sir g main ny MOSFETs change kyy hen running machine k driver k machine run hui hy but JB load para hy machine py to MOSFETs phr shot ho gay hen Kya ap rehnmai frma skty hen
Sir ji ye board ko ham inverter cfl ke liye use kar sakte hai kya
❤❤❤
thanks a lot
Aise circuit check karne ke liye series circuit mein kitne wat ka bulb lagana hoota ha.
sir ye transforme me noise kis liye ho rha hai ?? apne jab smps ko fix kiya usi time transformer se noise ayee
Can we send Honeywell DC's power supplies for repair.
Are you in Pakistan?
i am in Pakistan for next 1 week and then returning back to Jordan
i dont repair. but i can share repair and troubleshooting guidelines and you can repair yourself

Volt 12 DC supply SMPS AMP nahi aa Rahi kaise thik kare please reply
Good practical video.sir by mistake if these transistors blasted then how can we judge from circuit that it is transistor or mosfet base..what r the basic circuit differances between mosfet and transistor.by changing some modifications can these be replaced with each other or not.i never get the clear answer .you definately can give the real and clear answer .make some video on this topic.thanks for spreading precious knowledge.
Sir kiya is suplay ko dull suplay banaya jasakta he +12 0 12- jesi
Low output voltage same circuit me problem hai .Please solution btae

Sir matche suply laga sikhy
السلام عليكم ورحمة الله وبركاته
Sir ji....494...IC pe VCC only 8volts hai....load pe only 2 volts yate hai....without load 18 volts....
Sir isme load Dene pr 12 volt bulb 💡 laghle pr down ho raha he kiya falt ho sakta he
is ki voltage feedback circuit check krein, aur vcc section mein jo resistor rectifier diode key series mein hoti he. us ko check karein

جناب عالی کیا آپ ویلنگٹن مشین بنانا آف لائن سکھاتے بھی اگر آپ سکھاتے ہیں تو آپ کا ٹریننگ سینٹر کہاں پر ہے میں اس کو بنانا سیکھنا چاہتا ہوں اگر آپ نہیں سکھاتے تو میں ۰اس کو کس جگہ دیکھ سکتا ہوں
اگر آپ سکھا دیں یا کوئی اچھی جگہ بتا دیں تو تو آپ کی بہت مہربانی ہو گی
