Assembly Having Transformer and Inductor Properties and Method of Making the Assembly

摘要

An assembly having transformer and inductor characteristics includes a primary transformer winding coil and a secondary transformer winding coil, each wound around a core axis. The primary coil has outer peripheral primary coil portions spaced radially of the core axis outwardly away from central primary coil portions of the primary coil. The secondary coil has outer peripheral secondary coil portions spaced radially of the core axis outwardly away from central secondary coil portions of the secondary coil. The central primary and secondary coil portions are electromagnetically coupled and stacked in a close confronting adjacent relationship to form a transformer. The outer peripheral primary and secondary coil portions diverge radially and outwardly away from the core axis to form an inductance. The diverging outer peripheral primary and secondary coil portions bound an angle whose angular spread determines a magnitude of the inductance.
