Abstract
A rectifier assembly includes individual diodes arranged to form a full-wave bridge such that the silicon wafers of the diodes are loaded in compression. As so arranged, the centrifugal forces add to the compression forces on the diodes and on the electrical contacts therewith. The three-phase (AC) input conductors are connected by conductive straps which connect the diodes through to DC (+/−) terminal ring outputs. One surface of each of the diodes is in electrical contact with a conductive strap which then connects with the individual (AC) phases of an exciter rotor winding. The opposing surface of the diode contacts the ring diode pad on either the DC (+/−) output terminal ring. Two conductive posts, each of which are connected to only one of the DC (+/−) output terminal rings permit external connection to a main rotor winding.
