Abstract
In the design of transcutaneous energy transfer devices, variation in spacing between coils results in energy transfer efficiency changes. These changes may have significant effect on a system. It is proposed to provide a plurality of implanted coils for receiving energy simultaneously. Preferably, a plurality of coil pairs is used for transferring energy simultaneously. Also, a feedback system for use in a multiple coil system is disclosed.
