AS magnetic-amplifier circuitry has evolved from the saturable-reactor circuits to the self-saturating types, the basic limitations on magnetic-amplifier performance are inevitably associated with the nonlinear materials of the cores and rectifiers. The analytic descriptions of the core and rectifier characteristics introduce the critical parameters in a representation of the dynamic operation of the self-saturating types in contrast to the dependence of the saturable-reactor circuits on essentially linear resistance functions.1 Unrealistic assumptions concerning these nonlinear material functions, which under some circumstances might well be idealized, give results which are of limited usefulness to those concerned with the design and analysis of magnetic amplifiers as system components. |
