Mera nasib acha hai me apka subscriber bana thanks Sir dair se hi sahi apse contact ho gaya bahot badiya
welcome aur me aap ke sunehri shabdon keiley aap ka thankful hoon
Aap ka batane ka tarika bahut hi achcha hai
thanks a lot. best regards
thanks sir god bless u and your family i saw your dc inverter ac outdoor pcb explain. really very useful for us.sir we are expected indoor inverter pcb explain. we hope u . you will teach very soon.thanks sir,
yes brother i can explain but unluckily i dont have indoor board here. because i am in Jordan and here repairing is near to zero. they just replace the ac and destroy it. i asked some friends from pakistan and india to send me some circuit boards so i can share the repair process. i am still waiting for that
Like woe that's awesome excellent informative uploading big thumbs up thanks for sharing stay blessed with good health & great happiness/safety be connected thanks

Thanks for deep theory. Everything explained except for cold test or diiode continuity test on all pins and live voltages on all pins with reference to ground or pin 5. Please provide these vital readings for troubleshooting.
best regards
okay i will try to share the practical values of measurements as well
Good sharing stay blessed 👍
Salam...Hasseb bhai pin number 1 and 2 ko photocoupler se kese connect karenge ispe aik vidio bana den ke kese PWM control hogi uc3842 or 43 ki please...ke voltage output constant rahe...Allah apko achi sehat de ..Ameen...
please check video number 32, 34 and 76.
i hope these will clarify question. if something other, please reply

Sir kindly share circuit design pdf details as you explained in the vedeo so it is more clarity to basic level designers like me thank you 🙏🏼
assalamo alaikum Sir,
i watched all of yours videos they did a great help to me. and i have 1 question .If i decrease the voltage of smps and then apply load why the load fluctuates. and how to maintain frequency of a smps in case of low voltage . thank you
👍👍👍👍👍
thanks dear

agr mosfet ko +ve line me connect karty hein to transformer ki primery ka doosra end ground karein ge
ye mosfet k voltage stress ko calculate kr ke connect kia jaata he

Hello sir,
I have problem in 12v10a power supply, I used uc3842 ic which is continuously resetting at startup. On pin 7 (VCC) I couldn't get any stable voltage (fluctuate around 10-14v), there is no short circuit on primary or secondary side of circuit. If removed ic then there is stable 18v. I used 150k with 18v zener and 100uf capacitor, but didn't get any output starting pulse from output pin of ic. Is there any suggestions...

Sir, very nicely explained. Can you throw some light on CA888 5 wire module. Can this be used in circuit with IC3842 where TL431 is not used
we can use module in any circuit, just we need to know the vcc voltage and switching frequency,
i will discuss ca888 module as well
@@haseebelectronicsurdu I tried it in SMPS after removing MOSFET and 3842IC. But there is no stable output even without load
