ABSTRACT:
A poly-phase rectifier assembly for an alternating current generator includes five heat sinks, three of which are compression spring-loaded to form series electrical circuits to the poly-phase stator windings. The other two sinks are separated by a crush-proof, phenolic type, insulating gasket, and carry a plurality of semiconductor button-type diodes. The stator sinks are cupped to position compression springs, and are slotted for heat transfer. The stator sinks extend above the slotted positive heat sink into the cooling air flow area. A second embodiment utilizes back-to-back diodes, compression spring-loaded into a positive heat sink and a negative heat sink. A cupped stator heat sink forms a nest and provides series connection for the stator poly-phase windings. A plastic assembly supports a capacitor.
