Power boost auxiliary diode assembly for vehicle alternator

Claim 1

A power boost attachment for a three-phase star connected alternating current generator feeding a three-phase rectifier bridge, comprising a series-connected pair of diodes poled in the same direction with a common connection connectable to the center junction of the star connected winding of said generator and their other terminals connectable to positive and negative terminals of said rectifier bridge, so as to contribute to the output of said bridge when said center junction has an alternating voltage, all so constructed that: said diodes (20a,20b) are mounted respectively on conducting cleat plates (2a,2b); said conducting cleat plates are held in juxtaposition, except for a gap between them, by being held on the same side of an insulating plate (3) to which one connection (10'') of each diode penetrates, the other connection (1a) of said diodes being made to the respective conducting plates; a conducting foil or layer (4) is provided on said insulating plate (3) flush with the surface thereof on the side opposite said conducting cleat plates (2a,2b) so as to connect electrically the respective terminals of said diodes passing through said insulating plate (3); electrically conducting tubular connection means (5) provided with a tubular extension projecting substantially beyond the plane of said insulation plate are provided in said gap, mounted on said insulating plate (3), for making electrical connection between said conducting foil or layer (14) and said center junction of said star connected winding, and means (102a, 102b) are provided on said conducting cleat plates (2a,2b) to facilitate direct connection of each cleat plate to one terminal of the output of said bridge rectifier.
