10 MHz帯E級インバータの設計に向けた磁気部品の2ポート測定とモデル化

抄録

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.
