Hi All
I am also doing the same thing. In my case battery voltage is 12V and Fsw is 50 Khz.
My question is what will happen if kept the secondary winding open? in this condition i could not get the proper wave form of primary winding, there is to much spikes on the primary side also there is no effect of snubber in this contition.
Spikes is more then 100V is present.
Is the core is getting saturating? should i put some load on secondary winding.
Valuable reply will be appreciated.
Thanks
