Design of SMPS - Not sure what these spikes are being caused by.

Still missing a snubber in this circuit.
Zog:
I think I mentioned that  :)
The original one is there C11 and R7.

I am talking about a snubber across the MOSFET.
Zog:
Of course.
Please read back a few pages.
It has been mentioned  :)
Indeed it has even been drawn !  :)

P.S. do you have any clues as to why a center tap would reduce the amps out ?   ;D

Ok, my apologies.
It's not showing in the schematic in your last post, so that's a little confusing ;)

With the center tap probably something has to do with halving the inductance maybe
With a center tap I would suggest using a higher value.
