and ill send you the google drive link....

unless you know of a way i can somehow post the google drive link on here?

I guess there is a "Insert Hyperlink" buttion when you try to post a reply. You could use that.
Or just directly post the link as plain text incase you don't want to go through the hassle of doing all that.

Also thanks for offering your smps course would be delighted to hear more about that. Do you have any website with more details?

Resonant is probably not in the cards for such a wide output voltage range.  Well, actually Idunno, resonant converters can have nice output V-I characteristics.  You wouldn't get the constant-power sort of response that a boost/flyback approaches, but this doesn't make much difference in the charging rate, just a few ten percent at the low end.

What power level?

This is the link from my google drive

Please tell me if it doesnt work.

I've built several of the circuits this guy designed, and my own variations of them, they've worked well.

That is also a good way to limit the output of a ZVS oscillator by winding the primary and secondary on opposing sides of the core. This causes extra leakage inductance that makes the output sag under heavy load rather than trying to push more and more current into it.
