This paper introduces a new two-dimensional (2D) modeling approach for the fast calculation of inductor and transformer foil winding losses. The proposed modeling procedure is derived from the Partial Element Equivalent Circuit (PEEC) method, which is originally a full three-dimensional (3D) electromagnetic solution technique. With the presented modifications, the PEEC method can take into account...
The spiral inductors are extensively used in radiofrequency integrated circuits (RFIC) and are founding theirs applicability in wireless communications, in wireless power systems supply, in biomedical implants. The spiral inductors as component element of RFIC affect the performances of the devices in which they are used. To treat the problems that appear is necessary to analyze and model them in...
This paper presents a method for the calculation of the self- and mutual inductance of coils surrounded by air, positioned on top of a ferromagnetic plate and placed in a cavity inside a ferromagnetic plate. The magnetic fields around an array of air-cored coils are obtained by means of the three-dimensional magnetic vector potential using Fourier analysis. The current density distribution of a coil...
This paper presents a main flux oriented model of an induction machine which considers the saturation in both magnetizing and leakage inductances. The model is based on a virtual air gap. With this model it is possible to simulate the saturation characteristic and the cross-saturation effect. The validity of these results is proved with measurements on a test bench. A procedure is presented that shows...
