...Based on a concept previously discussed in [ 6 ], the losses and the excitation of the core’s “bulk” parts are simply calculated by a conventional estimation unit (CEU) assuming nominal values for limbs and yokes (see Section V-A)....

...On the other hand, the overlap regions of joints have additional losses which are represented by the “joint loss” . As suggested earlier [ 6 ], we express the latter by area related joint loss (in W/m2) for a core with four corners where an overlap design exists....

...c) For the narrow core, the joints’ contribution to excitation is small as long as is below its critical value which according to [ 7 ] is 1 T for (G4, G8), 1.5 T for (G2), and 1.6 T for (G6)....

...For an ANN of Type III, Fig. 13 shows examples of the predicted improvement which can be attained by replacing SSL ( ) by MSL ( ). The predictions reflect the industrial finding that improvements can be expected only for induction values which exceed the so-called critical induction , corresponding to saturated air gap bridges, which is close to 1 T for [ 7 ]....
