Abstract
A secondary circuit device including a secondary coil for transmitting and/or receiving magnetic energy of a magnetic field and converting the magnetic energy into electrical energy; a rectifier for rectifying the electrical energy; and a detection unit; wherein the secondary coil is connected to the rectifier via a conducting unit, the conducting unit for transmitting electrical active energy and an electrical reactive energy; the conducting unit connected to an input of the rectifier; the rectifier having an output for providing the electrical active energy as voltage and/or current; the detection unit connected to the input and/or the output of the rectifier to detect an overvoltage at the input and/or the output of the rectifier and/or an external magnetic field; and, when the overvoltage is detected, the detection unit is designed such that it influences the conducting unit and/or the magnetic field to limit the transmission of the electrical active energy.
