ABSTRACT:
The proposed device comprises a master pulse generator and a control unit. The master pulse generator is connected to a clock pulse counter coupled to a thyristor-pulse converter. The control unit is connected to a bidirectional pulse counter. The proposed device also comprises a decoder whose inputs are connected to the clock pulse counter and to the bidirectional pulse counter; an individual AND gate whose input is connected to the clock pulse counter and whose output is connected to a second thyristor-pulse converter; and two groups of AND gates, each AND gate having an input connected to the decoder. The proposed device also has a NOT gate whose input is connected to the decoder; a sign flip-flop whose first output is connected to the AND gates of one of said groups and whose other output is connected to the first individual AND gate, to the AND gates of the other of said groups, and to the bidirectional pulse counter. Furthermore, the device is provided with a second individual AND gate whose inputs are connected to the NOT gate and to the bidirectional pulse counter and whose output is connected to the sign flip-flop; a third individual AND gate whose inputs are connected to the control unit and to the bidirectional pulse counter and whose output is connected to the sign flip-flop; and a fourth individual AND gate whose inputs are connected to the control unit, to the bidirectional pulse counter and whose output is connected to the sign flip-flop. The proposed device also includes a circuit for passing time-shifted trains of control pulses fed from the decoder to the thyristor-pulse converters.
