Abstract
Disclosed are systems and methods for use of an inductive link for a communication channel in a transcutaneous energy transfer system. An example system may include a resonant circuit associated with an external primary, a power transistor connected to the resonant circuit and configured to drive the resonant circuit with a first time-varying electrical signal having a frequency, and a power driver connected to the power transistor that is configured to set the frequency of the first time-varying electrical signal to a resonant frequency to enable power transfer from the external primary to an implanted secondary. The example system may further include a communication driver operatively connected to the power transistor and configured to encode the first time-varying electrical signal with a data signal by modulating an attribute of the time-varying electrical signal as electrical power is transferred from the external primary to the implanted secondary.
