IMPLANTABLE MEDICAL DEVICE CHARGING

摘要

A particular method of providing power to an implantable medical device includes providing a first signal to a primary coil that is inductively coupled to a secondary coil of an implantable medical device. The method also include determining a first alignment difference between a voltage corresponding to the first signal and at least one of a current corresponding to the first signal and a component voltage at a component of a primary coil circuit. The method further includes determining a frequency sweep range based on the first alignment difference. The method also includes performing a frequency sweep over the frequency sweep range.

1. A method comprising:
providing a first signal at a first frequency to a primary coil that is inductively coupled to a secondary coil of an implantable medical device; determining a first alignment difference between a first signal voltage and at least one of a first signal current and a component voltage at a component of a primary coil circuit; determining a second signal at a second frequency based on the first alignment difference; and providing the second signal at the second frequency to the primary coil that is inductively coupled to the secondary coil.
