Abstract
There is disclosed a rectifier assembly for an AC generator for use with vehicles. The rectifier assembly comprises a single horseshoe heat radiating plate and electric circuit elements mounted thereon, and including at least one rectifier unit and two DC output conductor plates. The two d.c. output conductor plates are disposed in spaced relationship on one surface of the heat radiating plate with an intermediate insulating layer and electrically connected to output terminals of the rectifier unit. The assembly may be incorporated with a voltage regulator of an integrated circuit configuration for controlling the output voltage of the AC generator and a brush holder. The voltage regulator may be coplanar with the conductor plates.
Claims4
A rectifier assembly for an AC generator to be mounted in vehicles comprising;
- a heat radiating metallic plate of a horseshoe configuration, whose one surface is covered by an insulating layer,
- a pair of electrically conductive plates fixed on said insulating layer of said heat radiating plate and spaced from each other to give a space therebetween,
- a semiconductor rectifier unit for rectifying an AC output of the AC generator to produce a DC output, said rectifier unit being mounted to said heat radiating plate at the space between said conductive plates,
- said rectifier unit including at least one main rectifier element whose output terminal is connected to one of said conductive plates and an auxiliary rectifier element whose output terminal is connected to the other conductive plate, and
- means for fixing said heat radiating plate to the AC generator.
