Study of the sensitivity of the parameters in magnetic components

This work presents a study of the sensitivity of some parameters in magnetic components and their influence on the value of their parasitics. The influence of the insulator thickness, the effect of the air gap, the window height and the variation of the value of the capacitive effects as a consequence of the coil-former and insulator materials are some of the parameters that have been analyzed in this work. It is important to note that all these effects should be analyzed together when designing a new magnetic component. The study has been carried out by means of a frequency and geometry dependent model that accounts for 2D effects. The generation of the model and the parameter extraction procedure is based on the use of finite element analysis (FEA) solvers.
