Abstract

DC link circuit (5) for an electric power converter (1), comprising a smoothing capacitor (12) and at least two discharging units (15, 16, 17) being connected in parallel, with a control unit (18), which is configured to provide control signals (22, 23, 24) each controlling one discharging unit (15, 16, 17) and causing the discharging unit (15, 16, 17) to allow a flow of a discharging current (27) through the discharging unit (15, 16, 17) from the smoothing capacitor (12) during an on-time (29) and to suppress or reduce the flow of the discharging current during an off-time (30) , wherein the on-times (29) have a temporal offset to each other.
