Time-Domain Simulation of Mixed Nonlinear Magnetic and Electronic Systems
AD, Brown, JN, Ross and KG, Nichols (2001) Time-Domain Simulation of Mixed Nonlinear Magnetic and Electronic Systems. IEEE Transactions on Magnetics, 37, (1), 522-32.
This paper describes a technique for the simulation of complex magnetic systems intimately connected to any necessary drive electronics. The system is split into two Kirchhoffian domains, one magnetic and one electric. Two-way interaction between the domains is supported by a virtual device called a magneto-electric differential gyrator. Using this technique, arbitrarily complex, non-linear, hysteretic magnetic systems may be simulated in the time domain, coupled to any appropriate non-linear electronics, at a fraction of the cost of a comparable finite element calculation. The capabilities of the system are demonstrated by the simulation of a feedback-controlled current sensing system, and the simulation tracks the measured behaviour of the system well outside its linear region, to the point that the non-linear hysteretic core is being driven into and out of saturation, a consequence of a time delay inherent in the electronics. This is compared with a simulation of the same system using a 'conventional' electronic simulation, and the increased accuracy of this technique clearly demonstrated.
