A method for operating a traction converter circuit for coupling to an electric DC voltage network is stated, where the traction converter circuit comprises a network converter, which network converter on the DC voltage side is connected with a DC voltage circuit, wherein the DC voltage circuit can be switched to the electric DC voltage network, a transformer with a primary winding and a secondary winding, wherein the network converter on the alternating voltage side is connected with the primary winding of the transformer, a converter unit, which converter unit on the alternating voltage side is connected with the secondary winding of the transformer and where the network converter is controlled by means of a predeterminable network converter control signal (S<SUB>N</SUB>) for the setting of the network converter alternating voltage (U<SUB>G</SUB>). To simplify the traction converter circuit the network converter control signal (S<SUB>N</SUB>) according to the method is a rectangular signal which follows a reference rectangular signal (S<SUB>Clk</SUB>).
