ABSTRACT:
A method controls and monitors a parallel array of a plurality of rectifier bridges each of which is adapted to convert a plurality of alternating current voltages of a plurality of alternating current phases to a voltage. The bridges include a plurality of segments each of which has an element. Each of the elements of one bridge is electrically interconnected in parallel with at least one corresponding element of at least another one of the bridges. A plurality of control signals are output to repetitively fire the elements. Conduction or non-conduction of the elements is sensed. The method determines, for the elements of the bridges, if any of the elements of one bridge and all of the at least one corresponding element of at least another one of the bridges, which are electrically interconnected in parallel, have the sensed non-conduction. An alarm signal is output responsive to the sensed non-conduction.
