Abstract
Abstract A full wave rectifier assembly for use in an alternator includes first and second curved terminal plates. The first terminal plate carries a set of diodes with their cathodes electrically connected to the first plate, and the second terminal plate carries a second set of diodes with their anodes electrically connected to the second plate. The first and second plates are physically interconnected in insulated relationship when the assembly is mounted in an alternator, and the first and second terminal plates are so shaped that when the first and second plates are interconnected then the diodes lie substantially in the same plane.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
272 words
A full wave rectifier assembly, for use in a three-phase alternator, comprising, A first arcuate conductive terminal plate having first and second portions spaced apart by an integral neck, first, second and third semiconductor diodes carried by said first terminal plate with their cathodes electrically connected to the plate, said first and second diodes being carried by said first portion and said third diode being carried by said second portion, a second, arcuate conductive terminal plate having first and second portions spaced apart by an integral neck, fourth, fifth, and sixth semiconductor diodes carried by said second terminal plate with their anodes electrically connected to the plate, said fourth and fifth diodes being carried by the first portion of the second plate and said sixth diode being carried by the second portion of the plate, means physically interconnecting said first and second terminal plates in insulated relationship with the first portion of the first terminal plate positioned between the first and second portions of the second terminal plate and the first portion of the second terminal plate positioned between the first and second portions of the first terminal plate, so that the first and sixth diodes are adjacent one another, the second and fifth diodes are adjacent one another, and the third and fourth diodes are adjacent one another, and first, second and third conductive connectors, said conductive connectors electrically interconnecting respectively the anode of the first diode and the cathode of the sixth diode, the anode of the second diode and the cathode of the fifth diode, and the anode of the third diode and the cathode of the fourth diode.
Claim 2
Dependent Claim

A full wave rectifier assembly, for use in a three-phase alternator, comprising, A first arcuate conductive terminal plate having first and second portions spaced apart by an integral neck, first, second and third semiconductor diodes carried by said first terminal plate with their cathodes electrically connected to the plate, said first and second diodes being carried by said first portion and said third diode being carried by said second portion, a second, arcuate conductive terminal plate having first and second portions spaced apart by an integral neck, fourth, fifth, and sixth semiconductor diodes carried by said second terminal plate with their anodes electrically connected to the plate, said fourth and fifth diodes being carried by the first portion of the second plate and said sixth diode being carried by the second portion of the plate, means physically interconnecting said first and second terminal plates in insulated relationship with the first portion of the first terminal plate positioned between the first and second portions of the second terminal plate and the first portion of the second terminal plate positioned between the first and second portions of the first terminal plate, so that the first and sixth diodes are adjacent one another, the second and fifth diodes are adjacent one another, and the third and fourth diodes are adjacent one another, and first, second and third conductive connectors, said conductive connectors electrically interconnecting respectively the anode of the first diode and the cathode of the sixth diode, the anode of the second diode and the cathode of the fifth diode, and the anode of the third diode and the cathode of the fourth diode.
Claim 3
Dependent Claim
28 words
An assembly as claimed in claim 1 wherein the regions of the terminal plates around the diodes are perforated to define passages through which cooling air can flow.
Claim 4
Dependent Claim
