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 three planar, tear-shaped copper phase plates (62) which are equally angularly spaced about an axis (68) in a cylindrical housing (44). Six diode wafers (70) are arranged in two parallel planes which are perpendicular to the axis (68). Three diodes (70) in each plane are brazed (72) to one of the oppositely directed planar faces (63, 64) of the copper phase plates (62). The three diodes (70) in each plane are connected by an additional copper plate (78, 80) which forms an output.
