Abstract
Abstract A rotatable rectifier assembly which can be used to feed the field winding of a generator from an exciter generator that has a three-phase Y-connected output winding. The rectifier assembly comprises an annular insulator which carries three heat sinks on one side thereof and two heat sinks on the opposite side thereof. The three heat sinks form AC input terminals for the rectifier assembly and carry diodes forming part of a three-phase full-wave bridge rectifier circuit. The other two heat sinks also carry diodes and form direct current output terminals for the rectifier assembly. The heat sinks, when secured to the insulator, form alternate notches and flanges and the diodes are mounted on the flanges such that they extend generally peripherally of the assembly to facilitate connection of the diodes. The arrangement is such that two diodes are connected in series between a respective direct current output terminal and an AC input terminal and all of the diodes are mounted on heat sinks to facilitate operating the diodes at a proper temperature.
