A DC chopper features a setting device, which sets a required current value signal being dependent on a filtered input voltage such that an oscillation of the input filter device and an oscillation of the current are phase-opposed. The DC chopper may further have a control device, which, depending on the input voltage, supplies a control signal and adds the control signal to the actual current value signal supplied to form a controlled actual current value signal. The DC chopper may optionally have a disconnection device, which receives a switch-off signal on the input side and, depending on the switch-off signal received, supplies a ramp disconnection signal, and an adding node which adds the actual current value signal to the ramp disconnection signal to form an elevated actual current value signal.
