Abstract :
A hysteresis model of partial flux reversal in a ferrite core under voltage pulsed excitations is proposed in order to explain the relation between partial flux sets and the memory characteristics of magnetic analog memories. The model is based on the assumption that the slope of the irreversible region declines in proportion to the reversed flux level. The recurrence equations for flux levels derived from the model explain the hysteresis phenomenon in the meomory characteristics.
