This paper describes one method for calculating the flux-MMF relations
hip of an orthogonal-core. The calculation is based on a 3-dimensional
magnetic circuit model of the orthogonal-core. The model is derived b
y dividing the orthogonal-core, inclusive of the surrounding region, i
nto elements comprising a 3-dimensional magnetic circuit. Using this m
odel, we can compute the flux-MMF relationship of the orthogonal-core
with arbitrary dimensions from the B-H characteristic of the core mate
rial. The calculation method presented here is useful for optimum desi
gn of devices using an orthogonal-core.
