1) Actually i am making a transformer for my PUSHPULL DCDC Converter.
Shoild i be looking at inductor or tranformer design?
2) Do we select the core first or decide on the wind first?
best regards,
Thank you very for the advice.

I) I am using 20Khz for my Mosfet.
2) Am using this Mosfet(a little costly, S$10 each):VISHAY FORMERLY I.R
. - IRFP460APBF - MOSFET, N, 500V, 20A, TO-247AC
I beleive SG3526N should be able to drive it.
3) for the SG3526N , the output current is 100mA. I read from some papers, it says the...
1)
The spec for my circuit is
Pout=400W
Vout=350V
Is a simple opto coupler and zener diode suitable?
2) I am using 2 N channel mosfet for switching, that means i need 2 driver gate?

hi Sir,
Thanks alot, I do have some light on the part of the Mosfet, PWM and gate driver.
"BTW : for secondary , the start point isn't correct"
May i know which is the start point? Do you mean that the centre is tapped wrong at
the centre?
Do i physically get a block core that look something...
I have a small problem. I cannot really visualise how physically to even wind the core.

Am i right to physically wind the core as shown in the pix2 below?

Hi everyone,
First of all, i would like to say"Do not thrash me..".
I have some basic things to ask.
I am tryingto design a PUSH PULL converter.
I have gotten a few papers on studying how it works.
However look at the schematic i just cant visaulise how it works.
Q1) is there any idiot proof...
