Classification: CPC H  A | IPC A  H

Claim 0:
1. A transcutaneous energy transfer system for wireless transfer of energy, the transcutaneous energy transfer system comprising:
a transmitter unit comprising a primary coil configured to receive a supply voltage, the transmitter unit configured to be placed on skin outside of a human or animal body and transcutaneously transmit energy; and
a receiver unit comprising a secondary coil connected to an energy sink via a rectifier, a control unit, and a step-down converter, the receiver unit configured to be placed underneath the skin in the human or animal body and receive the energy transcutaneously transmitted by the transmitter unit, wherein the receiver unit is configured to detect a fault in energy flow from the secondary coil to the energy sink when an operating parameter of the receiver unit is outside of a specification range, wherein the energy sink comprises an energy store configured to supply energy to a cardiac support system, and wherein the energy store comprises an accumulator or a rechargeable battery;
wherein the control unit of the receiver unit is configured to actuate the step-down converter to perform a fault mode in response to detecting the fault by stepping down a voltage received at the secondary coil at the step-down converter and increasing a charging current for the accumulator or the rechargeable battery; and
wherein the transmitter unit is configured to:
detect the fault mode of the receiver unit based at least in part on an input power of the primary coil; and
perform a fault response by initiating an emergency shutdown of the transcutaneous transmission of energy to the receiver unit in response to detecting the fault mode of the receiver unit.
