Determination of Magnetic Induction and Current Density Values for Planar Cores to Operate with Minimal Magnetic Losses

Cláudio L. Ebert, Walter P. Carpes Jr, João C. S. Fagundes


This paper presents a methodology for determining the values of magnetic induction and current density in the design of transformers and inductors based on planar magnetic elements. From experimental values, datasheet parameters and through an optimization tool based on genetic algorithms, we obtain curves of magnetic induction and current density corresponding to operation with minimal magnetic losses. Hence, from the obtained results, it is possible to design a planar magnetic device operating with minimal losses.
