More Information
Summary:A thyristor converter control system comprising a voltage detector for detecting the thyristor voltage and a detector output suppressing circuit provided at the output of the voltage detector. The detector output suppressing circuit operates to detect an erroneous output of the voltage detector that it provides a voltage-presence signal while it must provide a voltage-absence signal, and cuts off the output of the voltage detector upon detecting the erroneous output from the voltage detector.
