Abstract
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) for the setting of the network converter alternating voltage (U). To simplify the traction converter circuit the network converter control signal (S) according to the method is a rectangular signal which follows a reference rectangular signal (S).
