Construction and modelling of a planar multi-layer electromagnetically integrated LCCT component

This paper describes the design and construction of a multi-layer multi-turn planar electromagnetic structure. This structure has the same functionality of a conventional discrete inductor, transformer and two capacitors. The structure was applied in a single switch single stage unity power factor converter. A 100 watt experimental converter was constructed and evaluated. An identical converter was constructed using conventional discrete components and the two compared. The integrated structure was analysed and an existing transmission line model is expanded to include multiple turns.
