Abstract
Magnetic coupling structures for wireless power transfer include overlapping coils which are configured to provide improved flux patterns. Control methods are used to determine the variation in coupling factor relative to alignment between the primary magnetic coupling structures and energise one or more coils of the primary magnetic coupling structure dependent on the relative alignment of the coupling structures to maximise coupling.
