Abstract
The invention relates to a discharge circuit (10) for discharging a high-voltage DC link (20) of a vehicle. The high-voltage DC link (20) comprises a DC link capacitor (30) to which a high voltage (U_H) is applied. The discharge circuit (10) is designed to adjust the level of the discharge current (I_D) provided by the discharge circuit (10) depending on the high voltage (U_H).
