A control unit for a six-pulse reversing (two-quadrant) thyristor converter is disclosed. More particularly, a first integrator is provided for generating a sawtooth voltage for controlling the thyristors associated with all negative half-waves of the applied phase voltage, and a second integrator is provided for generating a sawtooth voltage for controlling the thyristors associated with all positive half-waves of the phase voltages. Additionally, an evaluation circuit is provided which is responsive to the zero crossings and polarities of the phase vol...
