what is significance of D1? Because even if we did not have D1, current during switch on would have been same. Similarly, even when switch is off, then the current due to induced voltage would not reverse biase the D1. You are explaining it wrong. So why D1? I wish you clear my doubt as well as yours of using D1!
Thank you But you got the NT and D3 in the wrong configuration They shuld act as power restoration topology once the MOSFET is off and they will be in reverse bias when the MOSFET is on Please check it again
Superb explanation with well built animation. Thanks to you, I'm able to understand this topic really well in a very simple way. Keep up the good work. 👌😊
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??
Thanks for the video. My textbook has swapped Q1 and the diode in series with the tertiary coil. That's how I see it in most cases. Which one is correct?
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??
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?
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
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?

yeah it is only needed in switch on position, I also didnt get the significance of D1 there
What is the best isolated DC-DC converter topology under 500W output power?
Thank you
But you got the NT and D3 in the wrong configuration
They shuld act as power restoration topology once the MOSFET is off and they will be in reverse bias when the MOSFET is on

The Vídeo and explanations are very good. But the subtitles are hiding the circuito.
You can rearrange subtitles.
Please avoid background music

The direction of third winding must wind opposite of primary winding... check forward topology again ....
How that discharge winding diod becomes forward biased if it is heaving negative at anode from supply and positive at cathode from discharge winding 😅
It's dot polarity opposite to the main primary winding.

Hi, you can find the link of the document in the description of video
Any specific instruction for designing no of turns of reset windings
Check out this document

Thank you sir for right understand
Keep watching
Hi thanks for the detailed explanation, Can you use this to reverse the polarity of the output (i.e +v in, -v out)?
Thanks for the video. My textbook has swapped Q1 and the diode in series with the tertiary coil. That's how I see it in most cases. Which one is correct?
أشكرك وأقدر مجهودك ، تحياتي لك من تركيا.
Hello, can this converter increase voltage or only reduce it?
I have a doubt if saturation is possible in forward converter then isn't it possible in flyback converter
because the transformer primary's magnetic energy is being used in the secondary side of the circuit during operation
Does the Inductance of NT(inductor) must be equal to the primary side of the transformer ? Please reply 🥺🥺🥺
Not necessary
Who the hell is this guy? Thanks for the amazing videos!

Transformers does not work with DC current it only works with ac.
Okay
gracias por excelente explicación, tus videos son lo mejor...
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!
I have a question, our source is DC then why transformer is there??
source is DC but still the input coming to transformer is not pure DC, it is pulsating.
Thanks, these kind of videos help a lot , before reading equations. :)
Glad to hear that!
When mosfet is turn on then voltage across D3 is zero , how it possible
Thank you so much for watching!!
Can it run with only one diode on output side?
No
Great video, thanks for explaining it so graphicly.
Glad you enjoyed it!
Supperrrrrrrr. Thanks lots

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!!
