The hysteresis iron loss is give by Ph = Kh*f*Bmax^1.6
And eddy current loss is given as Pe = Ke*f^2*Bmax^2
At first it appears both loss increase with frequency (f) but recognizing that for fixed magnitude of applied voltage, Bmax = k/f , we can see that Pe remains constant and Ph decreases with increasing frequency.
So by operating power transformer designed for 60hz, at say 2khz, losses can be minimized.
Is this all right?
