Core-reset functions in magnetic-amplifier analysis part I ¿ A core-reset function

摘要

The operation of a magnetic amplifier is described by the differential equations of its physical system. In any analysis of amplifier operation the circuit equations resulting from the application of Kirchhoff's laws possess terms containing the voltages which are induced electromagnetically in the core windings by changing core flux in accordance with Faraday's law, and terms containing the various currents which flow in the windings. In general, a knowledge of the core properties relating instantaneous values of the rate of change of core flux ¿¿ and of net mmf (magnetomotive force) F of the currents in the windings is an essential part of a complete description of the physical system.
