- in this video i discussed #Full #Bridge Switching #Topology, Explained and Practical Circuit
A full-bridge converter topology, it is a transformer-isolated buck converter. it looks like H, a full-bridge converter is also known as an H-bridge converter
output is taken from a series connected pair of transistor, 2 pairs are connected in parallel, between the two legs formed by the switches Q1 Q4 and Q3 Q2. The switches Q1 Q2 and Q3 Q4 create a pulsating AC
voltage upper side transistor's collectors are connetced to +ve supply voltage, while lower side trasistor's emitters are connected to gnd input voltage. if one high side transistor will operate then the lower side transistor of the opposite pair will active. high side transistor will switch positive voltage to one line while the opponent lower side transistor will provide gnd to second output line.
when the cycle change, the first active pair will deactivate and the second pair will start switching. thus the output voltage polarity will reversed

My smart brother 😍 give you super 👍 for this amazing work
Thank you so much 😀
Very good experience like a practical lab in electronics engineering class with a great experienced lecturer. Have a great day. Thank you 🙏
Many thanks
nobody in youtube explains like you in every ditail and easy to understand ... god bless you brother thank you
Thanks and welcome
Good experience sharing keep sharing this informative video
thanks a lot
Very good and useful information sir thanks for sharing this knowledge to us
So nice of you
Lk 24
awesome work Haseem bhai
full wtch
Thanks, your teaching method is wonderful. See you soon
You are welcome!
Nice Sharing 👍🌹🌹❤️
best regards and special thanks

29 lk dear💕💕💕💕 super share Bhai
Masha Allah awesome share
Very informative and you explain very well. Keep up the good work. 👍
Jazaak Allah khair
Excellent explanation👍👍 have a great day 🙏🙏
special thanks dear sister
Excellent explanation
Assalamualaikum warahmatullahi, jazakallah khair for time and effort brother. الله يبارك لك في الدنيا والاخره ان شاء. امين
please accept my best wishes and special thanks
Excellent information
best regards and special thanks
Waalaikumussalam wr wb
Great sharing brother 👍❤️
thanks gor sharing your valuable knowledge with us..
Jazaak Allah khair
YES - very good. Now please explain Forward 2T with 2 clamping diodes.
Happy Sunday brother. Great upload
best regards dear sister
Helpful sir 👍
it is my pleasure
(Uganda).Am so happy for the new video. For me i download the en watch them wen am setled.if u ever go live pliz let us know en join the class.have u ever thought of using zoom fo the classes.think about it.
i am thankful for your love and appreciations
unluckily i have much free time to come live because i have to manage my office as well
Professor, it's a pleasure to see your videos, can you explain how a 10kva single-phase online UPS works, thanks.
Give a very good information brother
Excellent explanation
🙏 Ottimo spiegazione in pratica e teoria. Grazie 👍👏
un ringraziamento speciale e i migliori auguri. rimani benedetto
Very informative and nice explanation. I have never skipped ads whenever I watched your videos just to show my appreciations for your great effort. Thank you so much Sir 🙏🙏🙏.If you don't mind, could you please make a video of how to troubleshoot a 48v DC rectifier circuit with any brand like Linage Power or Emerson?Many thanks in advance sir🙏🙏🙏.
Good Work Liked It # 140
Big thanks
Superb video 👍👍👍👍
Nice circuit explanation
bravo man you are genius..baravo
i am thankful dear brother
clear explanation. this is also called h bridge circuit.
exactly it is also H bridge topology
Very nice 👍👍👌👍👌👍
Thanks a lot
Good 👍
it is my pleasure
Nice! Thank you Sir!
excellent explanation!! can you talk about how are the gate drivers supplied? for this topology how do you keep it isolated for tlp250?
Wonderful thanks
Most welcome
Walikum Salaam Janab Bhai Saab
thanks bhai sahib
Wahaliekum Musalam wallahamatulahi wabalakatu thanks nice work
Jazaak ALlah kharan dear brother
Cool. Is it possible to control the output voltage based on the phase shift?
Lk 20 brother 👏👏👏
Nice explanation
I'm confused with the low frequency full bridge inverter I see the connection I realize that in the low frequency full bridge pure sine wave inverter there's one long heat sink with 8 mosfets and that is where the battery positive is connected and there's another two heat sink separated and each has 4 mosfets and that is where the secondly of the transformer is connected both legs and the battery ground is connected separately also kindly explain the connection and how it works
Thanks, Haseeb ;
ifyou draw the motor in between the 4 "switchers" i think that would help too ?
please,one question: have here a solar inverter with 4 IGBTs, at rest, with the oscilator ( EGS002) out of the socket, and it draws over 50 watts without any load
( i have a suitable light bulb in series with the 3880 VDC,and in series with the big capacitors to avoid a blowout); all 4 IGBTs read ok on the multimeter diode scale;
Is it possible that 2 IGBTs,in the same line, are left in the ON state, at rest??
Or is it possible that even though the multimer reads ok, that some IGBTs are bad? and that would have to be 2 of them in line,right?
Please make a video on driver circuit of H- Bridge mosfeet of solar inverter
Brother you not answering my question that I asking in your previous videos about microcontroller. If anything goes wrong with microcontroller and as you explain in last video that depends on programmer who wrote the data into Microcontroller and there is no available source code for the microcontroller then what is salutation ??? Or we have to communicate with menfecturer of inverter ??? Or we have to completely dispose the inverter if you answer in your next video so will thankful for that if not also ok what can I say after all you are our brother
Best regards from Philippines
good morning/afternoon/evening??? friend....the resistors connected between the gate and the mosfet source...here are 4 mosfets...two with 3k resistors and two with 10k...can this difference affect the output?they are in parallel...thanks for your attention.
Nice
nice
👌👌👌👍
best regards and special thanks
i have one doubt. we have one multi output smps used in ultrasound machine. we check and figure out some beep sound comes from chopper transformer. what is the problem of chopper transformer
تحياتي اخي الفاضل عندي بعض القطع اريد معرفة ماهي والاستخدام وهل هي ذات قيمه كيف أرسلها وبأي طريقه وشكرا

Sir lekin high side waley donon MOSFETs ko ground nahi milta is like boots strap circuit lagaya jata hay woh kese kaam karta hay please explain
Sir im confused with watt power??for example in full bridge we have 4 mosfet lets say one mosfet is 300watts do we have 4x more power with 4 mosfets 1200wats and in half bridge with 2 mosfets 300watts we have 600watts,or whole bridge gives just 300watts,what topology give me more power or they are the same?can you explain to me please?
Sir aap ki qualifications bareme bataea.
bhai mein aik simple sa aadmi hoon, aik backward se village hoon, 1990 mein simple se electronics engineering ki thi aur us k baaad electronics field mein waqt pass ho rahaa he
Hello, my inverter draws more than 3 amps with a very low output (86Vac) with also low voltage at DC Capacitor (120v). Any idea where to look at ?
its one MOSFET section is not working
check both input fuses, and verify mosfets
might be some mosfet is short circuited
@@HaseebElectronics I checked all six mosfets and seem good. Can some short happen after the rectification which draws lot of current ? Thank you.
