摘要： An apparatus for igniting a fuel mixture provides an ignition system for generating a high-voltage ignition voltage, a circuit device comprising a circuit for superimposing a high-frequency signal on to the high-voltage ignition voltage, a spark plug in an engine block, and a transmission element having a high-voltage conductor which is guided in an insulation element. The high-voltage conductor is used for transmitting the ignition voltage, onto which the high-frequency signal has been superimposed, to the spark plug. Further provided is an electrically conducting shielding element which surrounds the high-voltage conductor in an electromagnetically shielding manner at least along one portion of the longitudinal axis of the high-voltage conductor. The shielding element is connected in an electrically conducting manner to a ground potential of the circuit device and establishes a connection between the ground potential of the circuit device and a ground electrode of the spark plug.

摘要： The present invention relates to a circuit for switching an AC voltage. It contains an input terminal able to be connected to an AC voltage source, an output terminal able to be connected to a load impedance, and a first series circuit. This series circuit comprises a diode and a circuit for storing electrical charges. The series circuit has a first end connection that is connected to the input terminal and a second end connection that is connected to the output terminal. The circuit for switching an AC voltage furthermore contains a DC voltage source, which is connected to an electrical connection between the diode and the input terminal or to an electrical connection between the diode and the output terminal and is designed to impress a DC current in the diode. The circuit for switching an AC voltage finally contains a first switch that is connected to an electrical connection between the diode and the circuit for storing electrical charges at one terminal. The first switch is designed to switch between a switching state in which a potential dependent on a reference potential is present at the electrical connection between the diode and the circuit for storing electrical charges, and a switching state in which an electrical floating potential is present in the electrical connection between the diode and the circuit for storing electrical charges.
