1. A rectifier assembly comprising:

  • a rotor shaft assembly having an inner non-conductive annulus;

    a first conductive diode carrier having an inner annulus and an outer periphery, the inner annulus including first, second, and third diode receiving surfaces disposed at spaced apart locations on the inner annulus of the first conductive diode carrier, the outer periphery engaging the inner annulus of the rotor shaft assembly;

    a second conductive diode carrier, electrically isolated from the first conductive diode carrier, having an inner annulus and an outer periphery, the inner annulus including first, second, and third diode receiving surfaces disposed at spaced apart locations on the inner annulus of the second conductive diode carrier, the outer periphery engaging the inner annulus of the rotor shaft assembly;

    a first electrical conductor connected to the first conductive diode carrier and extending to one end of the rectifier assembly to provide a first DC output;

    a second electrical conductor connected to the second conductive diode carrier and extending to the one end of the rectifier assembly to provide a second DC output;

    a first diode group comprising at least two diodes and a third electrical conductor for connection to a first electrical phase extending to the one end of the rectifier assembly and electrically connected to an anode of at least one diode of the first diode group and to a cathode of at least one other diode of the first diode group with a cathode of each diode of the at least one diode of the first diode group being electrically connected to the first diode receiving surface of the first conductive diode carrier and with an anode of each diode of the at least one other diode of the first diode group being electrically connected to the first diode receiving surface of the second conductive diode carrier;

    a second diode group comprising at least two diodes and a fourth electrical conductor for connection to a second electrical phase extending to the one end of the rectifier assembly and electrically connected to an anode of at least one diode of the second diode group and to a cathode of at least one other diode of the second diode group with a cathode of each diode of the at least one diode of the second diode group being electrically connected to the second diode receiving surface of the first conductive diode carrier and with an anode of each diode of the at least one other diode being electrically connected to the second diode receiving surface of the second conductive diode carrier; and

    a third diode group comprising at least two diodes and a fifth electrical conductor for connection to a third electrical phase extending to the one end of the rectifier assembly and electrically connected to an anode of at least one diode of the third diode group and to a cathode of at least one other diode of the third diode group with a cathode of each diode of the at least one diode of the third diode group being electrically connected to the third diode receiving surface of the first conductive diode carrier and with an anode of each diode of the at least one other diode of the third diode group being electrically connected to the second diode receiving surface of the second conductive diode carrier.
