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.
