A method for actively discharging an electrical energy storage device by means of an electrical circuit arrangement which comprises at least one half bridge comprising two switching elements, wherein the half bridge is connected in parallel with the energy storage device and wherein the switching elements each have a switchable section, the electrical resistance of which can be set in a transmission mode of the switching element by means of a control voltage of the switching element, wherein, in order to discharge the energy storage device, the level of the control voltages of the switchable sections of the switching elements in transmission mode and/or the ratio between a switched-on duration in which the switchable sections of the switching elements are operated in transmission mode during the discharge, and a switched-off duration in which the switchable sections of the switching elements are operated in a blocking mode during the discharge can be set as a function of a discharge current specification describing the level of a discharge current of the energy storage device.
A method for actively discharging an electrical energy storage device using an electrical circuit arrangement including at least one half bridge comprising two switching elements, wherein the half bridge is connected in parallel with the energy storage device and wherein the switching elements each have a switchable section, the electrical resistance of which can be set in a transmission mode of the switching element by a control voltage of the switching element, the method comprising:
A control device which is designed to generate the control voltages for at least two switching elements of at least one half bridge of an electrical circuit arrangement which can be connected or is connected to the control device, wherein the control device is set up to carry out a method for actively discharging an electrical energy storage device using the electrical circuit arrangement, which includes the at least one half bridge comprising the two switching elements, wherein the half bridge is connected in parallel with the energy storage device and wherein the switching elements each have a switchable section, the electrical resistance of which can be set in a transmission mode of the switching element by a control voltage of the switching element, the method comprising:
