An electric energy storage device which is connected to an electronic circuit is discharged by way of a first and a second electric conductor. A thyristor is provided for discharging the energy storage device. As a result of a fault occurring in the electronic circuit, a discharge current of the energy storage device begins to flow from the energy storage device to the electronic circuit via the first electric conductor and back to the energy storage device via the second electric conductor. The discharge current causes a magnetic field which changes over time to be generated about the first electric conductor and the second electric conductor. The magnetic field penetrates the semiconductor material of the thyristor. By virtue of the temporally varying magnetic field, a current is induced in the semiconductor material of the thyristor, and the thyristor is activated by the induced current.
