Abstract
A method for controlling a parallel array of rectifier bridges includes outputting control signals to repetitively fire bridge elements; skipping repetitive firing of the elements for one out of plural counts; sensing temperatures of the elements; averaging some of the sensed temperatures to provide a corresponding average temperature for each of the parallel bridge elements; comparing one of the sensed temperatures to the corresponding average temperature; increasing the counts when the sensed temperature of one of the elements is less than the corresponding average temperature, or decreasing the counts when the sensed temperature of the one of the elements is greater than the corresponding average temperature; and setting the counts to a first predetermined value when the sensed temperature of the one of the elements is greater than a second predetermined value above the corresponding average temperature.
