I wish I had these videos back when I started my journey into power electronics. Now, I rarely ever use these ASIC PWM chips. I almost always use MCUs. Cheaper and more flexible.
Salm sir g ...sir g batry charger me. Tl494 ic ko buht resistor aw pf capastor lagaye jate hy .awr app nay sirf ik lagaya hy...sir g ziada pf lagany ka koi khas paida hy ... Sir in last i love u too much
Sir Mera pass ak TV flyback he iska primary coil inductence ....4.20 mh push pull or half bridge no aux winding kese kerte he iska callculetion transistor callculetion ...iska driver ....plz sir ak video mujhe de do...sir plz plz plz
how to get inverting output from tl494? I have to connect it to a gate driver and the gate driver inverts the signal, and all the not gates i have are 5v logic so how to get inverting signal from tl494?
Sir I Received A Branded Smsps Acer Pc That Was STBY Is Ok And Ps On is 3.3 v And when Shot The Pson Run Fan Some Time Gose Off all Voltages Coming And Off After Fan Off PLEASE Give Me Solution
Thanks, I have a question: if R1=0 R2 = 5kohm then max ON time = 45 - 80= - 35 what does this mean? One more if we connect the feedback pin to one of the output pins of the TL494. What will happen to circuit? During push pull and single.
if R1 is 0 ohms. the Vref will applied to the dead time pin (pin number 4) and the threshold is maximum 3.3 volt, so the IC will go in disable state, (in upcoming video i am going to discuss dead time & soft start circuit, which is directly involved to pin number 4) error amplifier number 1 for voltage mode. i will arrange it practically error amplifier number 2 (pin 15, 16) for current sensing. we will do it practically as well. for error sensing technique, we have to design a reference which will applied to one input of EA, and sense line is connected to 2nd input of EA, feedback compensation is to be calculated to get proper regulation
Great work and very well explained sir.but I have no words for your appreciation
It's my pleasure

Thansk for Sharing
Your videos are very easy for understanding and very useful! Thank you!
it is my pleasure
Wonderful video dear friend, happy week.
You r really star ...اب بهوت اتشها ادمي اور بروفيشينال
best regards dear brother
Think you so much sir its I like your method to learning electronics...جزاك آلله خير وجعله في ميزان حسناتكم استاذنا الفاضل حسيب
Nice hard working may Allah bless you.
I wish I had these videos back when I started my journey into power electronics. Now, I rarely ever use these ASIC PWM chips. I almost always use MCUs. Cheaper and more flexible.
Which MCU types do you use for pwm push pull?
Asslam o alaikum ma sha Allah zaberdast sharing dear keep it up 👍👍👍👌👌may Allah give you more success amen
Thank you so much
Jazaak Allah khair
Thank you sir! Good morning!
Thank you Mr Haseeb tha was very useful
You are welcome
Excellent video to learn . Thankyou
best regards and special thanks
Very good and useful information thanks for sharing this knowledge to us
Good evening. Great informative upload brother
Great job Sir, Now please make easy and complete circuit or diagram as like working for power inverter primary section, Thank you very much sir!!!
very informative video sir ❤❤
thanks for sharing such a great video❤❤
Sir plz tell me where the feedback pin 3 is connected. And the potentiometer also
Have a nice day sir ,
Thanks,
Very good information. Thank you
So nice of you
Love for all your videos. Thanks

Brilliant person well explained
Thank you very much brother
One question
For 60hz LOW FREQUENCY inverter witch IC you recommend SG3525 or TL494 ?
Greeting bro,
Pls can you help with the Sg3524 circuit explanation
Subha Bakher Ho Bhai Saab
