ABSTRACT:
A control arrangement for a converter of the type including a direct current motor driving a three-phase generator with at least one exciter coil of the generator and/or of the motor being fed from the three-phase mains of the generator via a series connected transformer and a rectifier. At least one secondary winding of the transformer is connected in a closed series circuit which further includes a controlled thyristor, and two other secondary windings of the transformer which other windings are connected in parallel. In dependence on the parameter of the converter to be regulated, the control current of the thyristor is varied to provide a two-point regulation of the saturation current for the transformer flowing through the closed series circuit.
