ABSTRACT:
In order to monitor the conduction cutoff phase angles of a plurality of controllable rectifiers arranged in two groups in a rectifier bridge, a signal proportional to the angle for each rectifier is stored in a respective sample and hold member after each occurrence of a positive blocking voltage at that rectifier, and the minimum of the currently stored signals is observed.
