Abstract
An arrangement and a method for discharging a DC link capacitor, is based on the object of specifying a solution with which the DC link capacitor is discharged to values below the safety extra-low voltage within a specified time in the event of a hazard or malfunction, for example, if the high-voltage supply is disconnected or interrupted, and with which the lowest possible power loss results from the arrangement during normal operation. This object is achieved by the arrangement in that the means which discharges the DC link capacitor is a controllable discharge means which is constructed from a series circuit of a discharge resistor and a controllable resistor, and wherein the controllable discharge means is arranged parallel to the DC link capacitor.
