A METHOD FOR CONTROLLING A LINE CONVERTER ON BOARD A TRACK-BOUND VEHICLE

In a method for controlling a line converter on board a track-bound vehicle semiconductor devices of current valves of the line converter are controlled to be turned on and off so as to prevent the current (I) through a secondary winding of a transformer to which midpoints of phase-legs of the converter are connected to pass zero and shift direction other when the voltage across the secondary winding shifts direction by a start of a new half period of an AC line voltage across the windings of the transformer.
