1. A converter comprising:

  • a control device having two input terminals and an output side, a pulse width modulator having an input side connected to the output side of the control device;

    a load-side inverter having control inputs connected on the output side of the pulse width modulator and an output side with three output terminals;

    a current measuring device having an input side and an output side with two outputs, said input side connected to two of the three output terminals of the load-side inverter, said two outputs of the current measuring device being connected in one-to-one correspondence to two measurement inputs of the control device; and

    a two-channel damping control circuit having two control-circuit channels with corresponding inputs and outputs, with each input of the control-circuit channel being connected to a different one of the two outputs of the current measuring device, and with the outputs being connected to an inverting adder, wherein the respective outputs of the two control-circuit channels and the output of the inverting adder are connected to corresponding inputs of the pulse width modulator.
