A system for transcutaneous inductive power transfer to implanted medical devices was studied. A class E power amplifier with dynamic capacitive tuning was used in the transmitting part of the system to maintain constant power output to an implanted medical device. The influence of the operation mode of the implanted device on the output power range of the transcutaneous inductive power transfer system and its operational stability under conditions of coil misalignment was studied. In all modes local maxima were observed near the upper boundary of the output power range. The maximum values were almost identical for all operation modes of the implanted medical device.
