ماشاءاللہ بہت خوب بہت آسانی سے سمجھ آرہا ہے جزاکاللہ دوست آپ کی مدد درکار ہے ایک مائکرو کنٹرولر کا ڈیٹا نہیں مل رہا بہت سرچ کر لیا ہے اگر ہو سکے تو تھوڑا سا وقت دیجئے گا شکریہ و علیکم السلام
Asalamuwalaikum Dear Hasib Sir, Few days ago I repaired 1 smps (industrial) which output supply is 5v and output current upto 40 amps as mentioned on it. I've seen in secondary side there is 1 big size inductor coil and 2 mosfet connected to the transformer output. There is no rectifier diode I found in secondary side. I thought it might be some kind of dc to dc converter topology which delivers high rated amps, but I am still confused and very curious to know why there is couple of mosfet used ?
wa alaikum salaam bhai yes that is called synchronous rectifier it uses MOSFET and a rectifier controller ic as TEA1761, that ic senses the output voltage, output current and provides switching pulse to the mosfets gates. these mosfet works as a series switch
luckily i am also already planning to make a detailed lecture on this rectification process it is also known as controlled rectification diode is uncontrolled rectifier
Sir, I am a big fan of yours. Sir please identify and explain it for me. It would be very kind. My work is related to this type of power supply which is always needed now.
Assalamu Alaikum. Your presentation is great. Thank you so much, Ustad
thanks a lot brother
