ABSTRACT:
Apparatus and method for electrically interconnecting in and supporting the rectifier components a rotating rectifier assembly. An exciter rotor and the rectifier assembly are disposed about a generator shaft. In an embodiment providing full wave rectification, the rectifier assembly has a substrate having rectifiers mounted in a rectifying circuit on two exposed conductive areas. An ac lead extends from each of the ac windings in the exciter rotor to the rotating rectifier assembly. A bus bar has a bar section secured to adjacent rectifiers. The bus bar further has a tab section adapted to receive one ac lead extending from the bar section. A support ring is disposed about the generator shaft and secured to the recifier substrate, as well as the exciter rotor. The tab section from each of the bus bars is wrapped around the inner sleeve of the ring so that the centrifical forces exerted on the bus bars during the rotation of the shaft are opposed by the inner sleeve of the ring.
