Zusammenfassung:	An internal controller and an external power transmitter of an implanted medical device system and method therefore are provided. According to one aspect, an external power transmitter as part of a implanted medical device system includes processing circuitry configured to detect a shunting condition of an internal coil of the implanted medical device system, and responsive to detecting a shunting condition, reduce a magnitude of power transmitted to the internal coil.
