Power Electronics for an Energy Harvesting Concept Applied to Magnetic Resonance Tomography

摘要

In this paper the possibility of utilizing magnetic fields of magnetic resonant imaging (MRI) scanners for energy harvesting is investigated. The magnetic energy is converted into electric energy supplying small sensor systems that can be used for interventional medical applications within an MRI scanner. Suitable magnetic field components for energy harvesting are analyzed and a corresponding inductor design is discussed. Accordingly, a power electronic circuit is developed and successfully tested within an MRI scanner wirelessly powered by an inductor.
