ELECTROMECHANICAL INDUCTORS AND TRANSFORMERS

摘要

Devices and systems for power electronic circuits are provided. Embodiments of the present invention enable high density inductive energy storage by using electromechanical coupling between an electrically conducting inductive element and a mechanical resonator to passively store energy via both electromagnetic and mechanical mechanisms. A microelectromechanical inductor (MEMI) is provided utilizing a magnet and a conductor. In a specific embodiment, the MEMI includes a permanent magnet on a compliant layer centrally disposed within a spiral coil. In a further embodiment, a second coil is provided near the magnet to provide a resonating transducer.
