Because of its complicated flux behavior, shape effect of a ferrite orthogonal core (FOC) has not been made clear satisfactorily.
In this paper, a shape effect of flux control characteristic by flux components for an FOC is presented. The flux control characteristics of component method, ratio of virtual flux-path-length, sectional area of body, ratio of permeance and thickness of common part are examined. Performance evaluation of flux control is examined between flux control sensitivity and flux control.
The results, which are given by evaluation amount of flux control sensitivity and flux control ratio, show that the most respectable FOC has no thickness in common part, small amount of body and leg sectional area ratio, and the monoblock construction between the primary and the secondary side.
