ABSTRACT:
An electronic circuit senses that at least one circuit of rectifying diodes has been opened and response initiates an alarm. To sense one of the diode circuits being opened, the electronic circuit detects a temporary crossing of a low threshold by a DC voltage supplied at the rectifier output. The circuit is particularly applicable to high-power transformer-rectifiers aboard aircraft.
