Can you explain why both diodes are forward biased on 6:29 if current direction stays the same? On 4:37 D2 is off, what changed to make D2 forward biased on 6:29? Anyway forward biased D2 on 6:29 make no diference to me, what I overlooked?
Where exactly LLC and PSFB topologies are used in charger circuits? Like to understand the comparison between these two topologies, especially the merits and demerits over each other.
Very helpful explanation and well made video! I have a quick question. When all MOSFETS are turned off, do you first have to assume that all MOSFETS have the same voltage drop Vin/2 before concluding that Vp = 0? In your explanation, you first stated that Vp = 0 and then said the MOSFET voltage drop was Vin/2. I just want to make sure I understand the correct flow of logic. Thanks!
Well if you check the working, the MOSFETS which are getting shorted in the respective cycle don't have Vin/2 voltage across them & Np gets directly connected to the supply.
Great video! I had one question, that when a MOSFET gets off due to the inductor when energy will release than a spike appears on the Vds of the MOSFETs creating a type of ringing. How can we remove that voltage ringing? I had seen some snubber circuits but I need something more advance. kindly suggest
Snubbers are always the best option! I would suggest you to go for snubbers there are plenty of advanced snubber topologies which are efficient & cost effective. Apart from that I don't know any other method as of now, Sorry Mate!! Thank you so much for your appreciation!

these visual animations take a lot of effort and soo damn awesome. Thank u!
Thank you so much, Glad you liked it!!
This video is a real gift.... Thank you very much bro🎉
thank u! u are not foolish eng... u are far better than my electrical lecturer!
thank you so much Mate!!!

You explained very well thanks
7:04 "Doesn't affect the output". But the current flows through the Load. That seems like it's affecting the output.
Voltage stays constant
Why is the voltage Vin/2 when the mosfets are off?
Crystal clear explanation..Thank you so much 🙏🙏

i'll make a video on this
Ok, thank you. Awaiting your video
Very simple explanation. Do you have any video explaining LLC buck circuit?
Thank you, Not yet

If you're getting voltage spikes then you can use TVS diodes to supress them.

Hello. I need your help. i want to make smps design for electric car. which converter should i use? where should i start and how can i it ?
Generally PSFB converters are being used in EV chargers. the hardware is same as per full bridge converter but the controlling topology is advanced
you can also use LLC converter using frequency control
How to calculate trasnformator? Winding turn, spec wire and spec transformator?
Please check this Video, You will get a small Idea

@@FoolishEngineer thank you bro..
Nice work
Thank you!!!
Thanks
Thank you so much! Please show support to my video with Super thanks.
Pls can I achieve solar charge controller through this topology? If yes, then this transformer, is it ferrite core or iron core?
It depends whether you want to Step up the voltage or Step down and ferrite cores are used for transformers
