Control circuit for two thyristor pulse converters - has input of individual AND=gate connected to clock pulse counter control output and output to power thyristor

摘要

The control circuit, for thyristor pulse coverters, allows thyristors in two converters, e.g. a voltage converter and a field controller, to be triggered by the same components according to different laws. It may be used in the metallurgical, ship buildings, textile, railway, etc. industries. And AND-gate is connected to the output of a clock pulse counter and has its own output coupled to the power thyristor in the other converter. The circuit also contains two groups of AND-gates connected to clock and reversible counters, a NOR-gate, a sign flipflop, and two further single AND-gates.
