2-port Characterization and Modeling of Magnetic Components for 10 MHz Class-E Inverters Design

Abstract

This paper presents the equivalent circuit modeling method for magnetic components used in 10 MHz class-E inverters with 2-port measurement by network analyzer. The equivalent circuit parameter extraction procedures from measured S-parameter with S-Z and equivalent circuit transformation is explained. Magnetization characteristics of iron metal composite core and carbonyl iron core are assessed for the parameter extraction. Circuit simulation results of class-E inverters operation with obtained circuit models almost coincide with experimental results.
