Selecting the Operating Frequency of Magnetic Components for DC-DC Converter

This paper presents a new methodology to properly select the highest operating frequency for the magnetic components in power electronics devices. The magnetic core material, the eddy current effects, the skin and proximity effects, and the volume of the magnetic core are the parameters that are taken into consideration for selecting the highest operating frequency while maintaining the efficiency. The results of this methodology prove the effectiveness in maintaining the efficiency and reducing the volume of the magnetic core by 70%.
