Magnetic coupling enhancement using a flux transformer

Résumé

We explore the possibility of improving the magnetic coupling between two distant coils by using a flux transformer. A flux transformer is a short-circuited coil operating in constant flux mode. It could be an alternative for applications where it would not be suitable to use a magnetic core. From the circuit model of an air-cored inductive power transfer (IPT) system, we show that the flux transformer allows for magnetic coupling of systems separated by a large distance, even at low frequencies. A flux transformer can be practically obtained with a joint-free superconducting (SC) coil. We demonstrate here how this can be done using a laser-cut high temperature SC ReBCO coated conductor. Experimental results confirm the prediction of the circuit model and the corresponding finite element (FE) model. The flux transformer opens the door to new kinds of IPT systems.
