Abstract
Abstract A rectifier bridge assembly particularly suitable for use with an alternator having a voltage regulator controlled excitation winding, which assembly incudes two flat d.c. conductors lying in a single first plane, two or more a.c. conductors lying in a third plane, a layer of insulating material lying in a second plane, mechanically supported by the d.c. conductors and lying between the first and third planes, and two or more pairs of serially connected rectifiers arranged between the a.c. conductors and the d.c. conductors, one pole of the rectifiers in each pair of rectifiers being directly connected to one of the d.c. conductors and the other pole being directly connected to one of the a.c. conductors. A further d.c. conductor is disposed in the same plane as said a.c. conductors which further d.c. conductor is electrically insulated from the first mentioned d.c. conductors as well as from the a.c. conductors. The further d.c. conductor is directly connected to one pile of each of two or more further rectifiers and the other pole of each of the further rectifiers is directly connected to a different one of the a.c. conductors. The said further conductor has a plurality of spaced tabs corresponding in number to the number of said a.c. conductors, which tabs extend out of the plane of said a.c. conductors to points respectively above the individual a.c. conductors. An excitation rectifier is directly mounted between said a.c. conductors and said ends of said tabs. The first mentioned rectifiers are mounted directly on one or the other of the first mentioned d.c. conductors within individual wells in the insulating layer. The further regulators are for use in the voltage regulator circuit of the excitation winding of the alternator. Instead of having the spaced tabs on the further conductors, the tabs may be on the a.c. conductors and extend above the further conductor.
