Classification: CPC H  A | IPC A  H

Claim 13:
14. A method for transcutaneous wireless transfer of energy, the method comprising:
detecting, by a receiver unit placed underneath skin in a human or animal body and comprising a secondary coil connected to an energy sink via a rectifier, the energy sink comprising an energy store comprising an accumulator or a rechargeable battery configured to supply energy to a cardiac support system, a fault in energy flow from the secondary coil to the energy sink;
performing, by a control unit of the receiver unit, a fault mode in response to detecting the fault by increasing a charging current for the accumulator or the rechargeable battery, wherein the fault mode is performed by the control unit actuating a step-down converter to step down a voltage received at the secondary coil at the step-down converter;
detecting the fault mode by a transmitter unit placed on the skin outside of the human or animal body, the transmitter unit comprising a primary coil configured to be supplied with a supply voltage; and
performing, by the transmitter unit, a fault response by initiating an emergency shutdown of a transcutaneous transfer of energy to the receiver unit in response to detecting the fault mode.
