Great video, thanks for explaining it so graphicly.
Glad you enjoyed it!
Thank you sir for right understand
Keep watching
Small correction.... D equals the ON time divided by the switching frequency cycle time and not by OFF time.
Please accept my apologies for the mistake!
Any specific instruction for designing no of turns of reset windings

What voltage source u r talking about? Battery?
My doubt is when inductor discharges the energy stored in it, will supplies like tdk lambda really take back energy from this inductor??
or its simply dissipated somewhere out of converter??
Not battery, a constant DC source. Thank you so much for watching!!
Hey i am watching here at Korea Thanks for your video, it help well. But i am still feel difficult about forward so do you have any pdf material of forward converter??
Hi, you can find the link of the document in the description of video
When mosfet is turn on then voltage across D3 is zero , how it possible
Thank you so much for watching!!

Hello sir, Thank you very much for your highly informative video. I have a question about the wire gauges, do we need to select it according to switching frequency or can we use thicker wire. What about the demagnetizing winding and secondary winding gauge?
Foolish Engineer - 2021-03-26
Wire gauge depends on the the current flowing through the inductor, but if you increase the wire size, the skin effect increases, so there is a trade of between these quantities
Md. Arifur Rahman - 2021-03-26
Thanks for the quick response, as we know, in single switch forward, when switch turns off, the polarity of primary winding reverses (That's AC effect) and the reset winding does its job. To get the best ampacity we need to choose primary winding gauge according to switching frequency. This part I'm clear now.
What about Secondary winding? In secondary winding, the diode only stops conducting when the current becomes zero and works only one way, there is no AC effect thus no Skin effect (if I'm not wrong). Can we use thicker wire in secondary?
