This paper is an extension of the gyrator-capacitor more model introduced by D.C. Hamill (1994). This core model is simple, efficient and handles both linear and nonlinear cores. The only item lacking is an efficient core loss element for determining circuit Q and efficiency. The gyrator re-cap core model contains a core loss element that takes into account both eddy current and core hysteresis losses. This paper describes the model and then demonstrates how to use it to accurately model the following magnetic devices: inductor; transformer; flyback transformer; ferroresonant regulator; and flux gate magnetometer.
