Are you thinking I have + and - rails and one can be overloaded creating an imbalance in the core?
Maybe I misled my supply has only one rail, froma center tapped secondary, the ends of the windngs go to a To247 package dual diode.
One end of the primary goes through a series capacitor.
Mode is voltage.
No primary current sense, there is crude current limit on the o/p but no short protection, havent got that far.
There is a snubber on the primary, but not on the rectifiers, there is some parasitic overshoot but its within the rectifiers rating.
