Abstract

The digital control has a decoder connected by its inputs to a clock counter and an up/down counter, a control unit and AND-gates. A change-over circuit comprising seven AND-gates, a NOR-gate and a delay line is also included. The first inputs of the first two AND-gates in the change-over unit are connected to the output of the clock counter. The output of the first AND-gate is connected to the gate of one main thyristor and one charging thyristor in the inverter. The second AND-gate's output is connected to one shut-off thyristor.
