ABSTRACT:
A compact rectifier assembly for use in a synchronous electric machine having a rotor. A circumferential housing surrounds a plurality of discrete diodes mounted within the housing. The housing is fabricated of non-conductive material and adapted for incorporation in the rotor of the machine. The diodes are mounted on and electrically coupled to mounting plates fixed directly to the inside of the non-conductive housing, the mounting plates also acting as heat sinks. The housing includes a pair of interfitting non-conductive parts to facilitate assembling the diodes within the housing, and the housing is configured to define a sealed chamber about the diodes for the passage therethrough of a coolant.
