Abstract
A traction current converter includes a line-side four-quadrant converter which is provided with turn-off power semiconductors that are implemented as current converter valves. Each of the power semiconductors is connected electrically back-to-back in parallel to a corresponding power diode. A regulating device has an output side which is connected to control terminals of the power semiconductors. Each of the power diodes is implemented as controllable power diode which can be connected on the control system side to a corresponding diode control device having an input side which is connected to control outputs of the regulating device. In this way, the four-quadrant converter of a traction current converter can be reliably operated without having to use power semiconductor modules with enlarged diode chip surface.
