Sir, Aapke great knowledge ko mein salam krta hoon. Jitne bhi meine aapke videos dekhe U are a genius teacher. Bahut deep study kiya hai aapne aur aap electronics ke master ho. Jo circuit hame dekhke chakkar aata hai. Use aap bahut aasani se samzate hai. Aallah aapko sada khush rakhe. Yahi meri ibadat hai
Congrats for the brilhant lesson. I did not understand why not heatsink on mosfets. Eight mosfets handling 3000VA perform more than 30A by mosfet. Thanks.
best regards when it is fitted in chassis, the outer body works as heatsink, and the outer body have fins of heat sink in air, so it is open air cooled
Awesome series of videos bro, subscribed. I learned a lot about High frequency inverters and their topology. Also how they are designed. Do you know why this inverter might have blown the High voltage boost stage? Any common reason for failure?
thanks for the great vid and information. when testing, how does installing 1 mosfet in each section prevent failure? i would also like to know if limiting current from input power supply is also needed during testing?
thanks a lot if we will increase swith frequency, in that case we have to re-design smps transformer, because the current transformer is designed for 33KHz push pull operation.
Hi you are a very good teacher, please can you do a video on Sukam inverter that uses PIC processor for PWM signals , i have a problem with such inverter sending 100Hz signal instead of 20 Hz signal per cycle.
Salam M Haseeb, any idea on how to turn modified sine wave inverter or UPS into pure sine wave in order to be able to make fridges working ? thank you.
Some inverter to senosoidal pure have a termical sensor KSD 304 250 v 10 a 45 C. It dosnt start whit the normal closer sistem! Could you show us a 2000 w 24 dc in a example?
Hello sir I will like to get some help from u check one inverter dc v at capacitor is 300v but no ac output and all transistor re good and have 300v supply
hi sir I appreciate your work my question is incase you dont find the same mosfate number what will you do ? will others mosfates work secondly if you don't have oscilloscope how can you use a multimeter to troubleshoot thank you sir
laptop charger I'd resistance method use karta he. different laptops me id resistor value different hoti he so cahrger apni output ko laptop ki requirements k hisaab se set karta he (that is possible through I'd resistance)
Hello!! I have been trying to repair an inverter (souer SDA-600AF)....//BOARD NUMBER ''APPEARS " TO BE SDA250 07/06/28 ,But it is not available in any website. Its problem is that both neutral and live glows on neon tester.....and it keeps shutting on and off whenever a load is connected. what might be the problem?
Salam M Haseeb, is there any relationship between those 3 concepts : "Current sensing" and "Voltage Drop" and "Ohm Law" ? i am having hard time to understand them theorically.
Its very sensirive if you increase the frequency..it will disable rhe inberter..thats why its sounding like that...don connect the sonds on capacitor..rather on a diode but its the same rhing with frequency hehe
It is not a solar inverter,no charge controller,only constant in put 12volt, Now I suff.from solar inv.,,I make a inverter run on direct solar panel,, to connect series 120v ,,,safe,,change40v for inverter,can SMPS or mppt try ,
it is not solely solar inverter. but here in Jordan it is called solar inverter, and it is also printed name by the manufacturer "3000VA SOLAR INVERTER" its input is 8 volt to 40 volt DC
you are checking mosfets wrong. mosfets can't be checked in board mosfet best way to check Drain to Source diode value and 2nd part Drain to gate no value on meter however after repeat same procedure drain to source it must show short because N type mosfets has small capacitor inside .

You are the best! Thanks you Sso much!
You're welcome!
Fantastic Work Janab Bhai Saab
thanks a lot. stay blessed
Explanation was 100% good 👍
thanks a lot
Hi friend thanks for the informative series and I also see that an oscilloscope is really important to use, to determine the proper drive signals
best regards
yes the oscilloscope is important in modern electronics
Your videos are great, you do a wonderful job of explaining things...
best regards and special thanks for your valuable appreciation
Have a nice day
Superb video 👍👍👍👍
Wonderful upload dear friend, happy day!!!

Do you know why this inverter might have blown the High voltage boost stage? Any common reason for failure?
Great series would like to see how house voltage and hz is monitored and feed back to control output in a grid tie inverter thanks
god gives you so big help and chance your life. thanks haseeb abi :)
Beautiful information.
special thanks

Hi sir..,how are you.
I really learned a lot from this series and I am waiting for next part.
Thank you very much. Good night 🙏
Excellent explain
Glad you liked it
Great full thank you so much Sir
Most welcome
Bardzo mi się podoba twoja praca pozdrawiam serdecznie 😄👍
thanks a lot
Very helpful video. Thank you very much Sir. Sir which type of power mosfet/igbt/diode in o/p and i/p stage used in it .
best regards
@@HaseebElectronics sir you haven't replied that what was igbt number used for output section and mosfets number for driving Transformers?
ما شاء الله، بارك الله فيك. If we change TL494 ic to a higher frequency say 100khz, what will happen to the circuit.
thanks a lot
if we will increase swith frequency, in that case we have to re-design smps transformer, because the current transformer is designed for 33KHz push pull operation.
Salam Haseeb
thank you for sharing knowledge
How the duty cycle is full in no load
Best regards
The duty cycle is being displayed as inverted signal. So it is looking maximum duty cycle
Actually it is minimum cycle
thank you , I have old inverter the output voltage is 150 v ac , I want know why cases the output voltage decrease
if voltage at dc capacitor is maintained at 300+ volt
then output switch (H-Bridge switch is not switching properly), or its mosfet drive is missing
Good day brother. Great sharing from a pure heart brother. Keep sharing
Awesome explanations !! great videos !
Will this inverter will be able to run full 3000 Watts ? Thanks !
best regards
the sticker on the inverter body claims 3000VA, but i think it have no capability to drive above 1000VA
و السلام عليكم ورحمة الله شكرا لك أخي

How to test the signal with multimeter setting on voltage
Sir without oscilloscope maltimeter se gate single ko varify kaise kare asa sort vidio banaia
What is output ic number? The ic that drives the H topology mosfets of the output by providing 50-60hz signal. What is the ic number?
hi sir I appreciate your work my question is incase you dont find the same mosfate number what will you do ? will others mosfates work
secondly if you don't have oscilloscope how can you use a multimeter to troubleshoot
thank you sir
Yes other Mosfets will do providing they are same specifications or better
Sir mere pass ek loptop charger h jiska
o/p 20v 3.25A, 15v 3A, 9v 2A, 5v 2A, ye kaise posibal h.
laptop charger I'd resistance method use karta he.
different laptops me id resistor value different hoti he
so cahrger apni output ko laptop ki requirements k hisaab se set karta he (that is possible through I'd resistance)

sure
everything is possible. all electronics is revolving around ohm law. nothing is outside from ohms law's approach
@@HaseebElectronics it is then time for me to really understand it...
@@hichamtassi1753 Just remember that ohms law must always be obeyed. If ohms law doesn't fit then your math or your circuit is wrong..
I have a 500watts inverter, 294v present at capacitor but 0v AV output
Assalaamu alaikum. My bench power supply voltage stops working. I accidentally short it out, u think a mosfet or capacitor burnt?
possible there may a output current regulator transistor is bad. it is most f time at output stage
@@HaseebElectronics salaam. Thank you. How can I fix ?
👍👍👍
How can I check gate signals without oscilloscope
please check video number 550
Sir mosfet short hona pa dc terminal short ho jata hai uska koi tarika ki na ho
Its very sensirive if you increase the frequency..it will disable rhe inberter..thats why its sounding like that...don connect the sonds on capacitor..rather on a diode but its the same rhing with frequency hehe
