Synthesis of a Cauer Equivalent Circuit for Electric Devices From Computed and Measured Data

This article proposes a method for modeling electric devices based on Cauer circuit whose parameters are directly determined from measured or computed data using the adjoint variable method. It has been shown that governed by quasi-static Maxwell's equation can be modeled circuit. From synthesized circuit, eddy current losses evaluated wide frequency range. Moreover, it embedded into simulator to perform time-domain analysis. is identified proposed works better simple numerical model than genetic algorithm. equivalent of reactor and power inductor input impedance well approximated over domain interest.
