Dynamic core behavior and magnetic amplifier performance

ANALYSES of magnetic amplifier systems commonly suffer from a recognized weakness; the magnetic behavior of the cores is approximated by more or less extreme idealizations. Descriptions of amplifier performance therefore, are seldom better than semi-qualitative, and those analyses, even though valuable for the understanding of the operation of the various circuits, may not satisfy the more specific needs of the designer who is interested in quantitative predictions. In fact, even without direct experience in the field, one cannot fail to detect a discrepancy between the acceptance of excessively simplified representations of core behavior in the analyses and the need for increasingly refined core-testing procedures that seems to be felt in industrial amplifier production.
