“…These effects and the great variety of core geometries (e.g., E, RM, POT, toroidal) and other parameters, such as the number of turns, make it difficult to obtain a single model that is both simple and precise. Of all the geometries, the toroidal core ( Figure 1 a) is the most studied in current literature [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Nevertheless, despite these publications there are not enough studies that calculate parameters to be used in circuit simulators, such as inductances in all working regions of the ferrite (linear, intermediate and saturation), geometries and number of turns.…”

“…3 where we show the distribution of the values of the B-field module on the surface of a saturated RM core, displaying a higher concentration on the central column. Therefore, the modeling of these ferrite inductors is a complicated task [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] as it involves solving nonlinear differential equations which cannot be solved by analytical equations. In order to model them it is necessary to measure the magnetic properties 7,8,9,12 and use design, simulation and Finite Element Analysis programs 14,15,17,18 .…”

“…Como resultado de ello, algunas curvas pueden diferir con respecto a los resultados experimentales y puede aparecer algún comportamiento sin sentido físico en las curvas calculadas. El peor comportamiento que puede presentar el modelo de Preisach clásico es la pendiente negativa de la curva inversa que produce inestabilidades en las ecuaciones magnetodinámicas [Zirka, Moroz, Marketos, et al, 2002].…”

“…En general, la formulación en A-U es la preferida para la resolución del campo magnético por métodos numéricos en máquinas eléctricas o sistemas electromecánicos pues es la que permite tratar mejor las diversas fronteras que aparecen en tales equipos (entre otros [Ida y Bastos, 1997;Steele, 1997;Salon 1995;Saitz, 2001;Bottauscio, Chiampi, Dupré et al, 1998;Albanese y Rubinacci, 1992;Nicolet, Delincé, Bamps et al, 1993;Zhai y Vu-Quoc, 2005;Kim, Jung y Hong, 1998;Lee y Jun, 1999]).…”
