Abstract

One of the most important magnetic materials is ferrite which is used in many high frequency applications such as Switch Mode Power Supply (SMPS), high frequency transformers and inductors and etc. Ferrite cores can be affected by different parameters. In this paper, a typical high frequency transformer with ferrite core is designed and simulated in ANSYS software. Temperature rise due to winding current (Joule-heat) is considered as heat generation source for thermal behavior analysis of the transformer. In this simulation, the temperature rise and heat distribution are studied and the effects of parameters such as flux density, winding loss value and using a fan to cool the winding and core are investigated.
