DEVICE AND METHOD FOR DISCHARGING A DC LINK CAPACITOR

摘要

The present invention relates to a device for discharging a DC link capacitor, the device having a discharging unit for discharging the DC link capacitor, the discharging unit being connected or connectable between two connection terminals of the DC link capacitor, discharging of the DC link capacitor being controllable by means of a control voltage applied to a control input of the discharging unit. The device also comprises a control unit, which is designed to apply the control voltage to the control input of the discharging unit, wherein the control unit is further designed to vary the control voltage during a discharging process or at the start of a process for discharging the DC link capacitor.
