ABSTRACT:
A device for digital control of a polyphase thyristor-pulse converter comprises a master oscillator connected to a clock pulse counter. The clock pulse counter is connected to the power thyristors of the thyristor-pulse converter through a decoder for time-constant pulse trains. The device also comprises a control unit connected to a bidirectional pulse counter. Furthermore, the device comprises decoders for time-shifted pulse trains, each decoder having inputs connected to the logical outputs of the clock pulse counter and having outputs connected to the other power thyristors of the thyristor-pulse converter.
