- Help solve tangled transformer freq contradiction over induction heating

As a transformer freq bet higher, inside induction get more efficient i.e. less loss:

1. Hysteresis loss =

2. Eddy current loss( proportional to B2mf2Bm2f2 )

Now it seems that losses increases with increase in efficiency...

But the above equations are valid when max flux density Bmax remains constant.

The gist is that when increasing the frequency flux density does not remain constant, it actually decreases with increase in frequency, as

V = 4.44 . Bmax . A . f . Tp

Now how is it on Induction_heating, as it's read more, the more contradiction is to above

1. Hysteresis loss =

**η * Bmax^n * f * V**.2. Eddy current loss( proportional to B2mf2Bm2f2 )
