Abstract
A wireless power system for an implantable device is described. The system includes multiple inductive charging coils to increase an effective area for receiving an electromagnetic charging field from a wireless charging device. The multiple inductive charging coils produce different alternating current signals in response to receiving the electromagnetic charging field. The system includes a rectifying circuit for rectifying the alternating current signals into direct current signals. The system also includes a current combination circuit for combining the multiple direct current signals into a single direct current for powering an operation of the implantable device. Methods and devices for implementing the power system in an implantable device are also described.
