Modified Gyrator-Capacitor Model for Circuit Simulation

A modification to the gyrator-capacitor (GC) magnetic model is proposed to correct possible errors when simulating magnetic structures using the GC model on electronic circuit simulators. The proposed method introduces a conduction path for the dc component of the magnetic flux caused by a dc bias current - a path missing from the original model. This modification ensures the correct distribution of magnetomotive forces (MMFs) across the capacitors. The conduction path is achieved by placing resistors in parallel with the capacitors, ensuring the proper distribution of the dc component of the MMFs. Theoretical analysis, supported by circuit simulations, validates the effectiveness of this approach.
