Hello,
In a Flyback SMPS, when the FET switched off, the drain nide voltage shoots up to the clamp level, and then the clamp voltage appears across the primary. Throughtout this time, what proportion of the primary coil voltage is across the leakage, and what proportion is across the coupled-in part of the primary coil.?
Is it just going by the rule of inductors in series?
....if so, then that would mean theres hardly any voltage across the leakage, and it would therefore take ages to discharge.
....so evidently, the rule of inductors in series cannot apply here.....but why not?
