1. A method of monitoring and controlling power transfer between a primary assembly and a secondary assembly of a transcutaneous energy transfer system, comprising:
operating the transcutaneous energy transfer system in a first power mode, the first power mode being one of a plurality of scalable power modes;
determining if the transcutaneous energy transfer system is to be switched to a second power mode, the second power mode being one of the plurality of scalable power modes, wherein determining if the transcutaneous energy transfer system is to be switched includes at least one of:
determining if a request to enter a fault mode is received;
determining if a predetermined time has elapsed since power up;
determining if a predetermined time has elapsed since a fault condition was detected;
determining if a predetermined time has elapsed since a change in a coupling coefficient occurred;
determining if a fault condition is detected;
determining if a change in a coupling coefficient is detected; or
determining if a load change is detected; and
switching from the first power mode to the second power mode by controlling power transfer between the primary assembly and secondary assembly.
