Patent ID: 7511392

Claim:
A rotating rectifier module for rectifying a multiphase alternating current provided by a multiphase alternating current power supply, the rotating rectifier module comprising: a housing having an outer surface, an inner surface defining a central opening for receipt of a rotatable shaft, and at least one cavity located between the outer and inner surfaces, each cavity being defined in the housing by an outermost and an innermost surface; a circuit board mounted at an end of the housing and having a first side facing away from the housing and a second side facing toward an interior of the housing, each side defining a plane substantially normal to an axis of rotation of the rotating rectifier module; a plurality of input terminals located on the first side of the circuit board, each input terminal being electrically connectable to one phase of the power supply; a first output terminal and a second output terminal each located on the first side of the circuit board and being electrically connectable to a direct current load; and a plurality of rectifier circuits electrically connected in parallel between the first and second output terminals, each rectifier circuit being mounted inside one of the at least one cavity on the outermost surface that defines the cavity and being electrically connected to one of the input terminals.
