    Abstract: The problem of assembling and maintaining good electrical contact in a rotating rectifier assembly (40) is solved using brazed connections. The rectifier assembly (40) includes a cylindrical housing (44) receiving a pair of coaxial copper plates (50,52) which act as outputs. Each copper plate (50,52) has three angularly spaced, square-shaped diode wafers (64,70) brazed thereto on one face. The opposite face of each diode wafer (64,70) is brazed to a conductive strap (68,74). The straps (68,74) extend radially outwardly. The two plates (50,52) are angularly aligned so that their respective diode wafers (64,70) are in angular alignment, with the straps (68,74) for the aligned diode wafers (64,70) of each plate (50,52) being soldered together to provide a phase connection. A conductive strap (58,60) is brazed to each of the two plates (50,52) for connection to conductive posts (48) which connect to the main field (32).
