inductance value. This will make the volume of the overall inductor or trans-
former grow, but it is necessary for a greater margin of safe operation for the
power supply.
The major losses within any core material are the hysteresis loss and eddy
current loss. These losses are typically lumped together by the core manufac-
turer and given in a graph of watts lost per unit volume vs. the peak operational
flux density (B
max
) and frequency of operation. Hysteresis loss is given as
(D.5)
where k is the hysteresis loss constant for the material.
v is the volume of the core (cm
3
(CGS), m
2
(MKS)).
f is the frequency of operation (Hz).
B
max
is maximum flux density ...
