HW9 problem 3 help

All,
I would like to know if anyone else is getting something besides Js=1.
Here is my approach. I have an equ. ckt like the boost with a half wave ZCS QR switch from the lecture notes. The current source is the current through Lm reflected to the secondary. If Js=1, then ton will be a specific value and not a range. Any help would be appreciated.

Hi Joe,

You might want to check your Vbase. Normally for a flyback Vbase=Vg+V/n. If you choose Vbase=Vg, you'd get Js=1.

Regards,
Toby
