  • Patent number: 5812388
    Abstract: An improved bridge rectifier for an alternating current generator includes a first heat sink having a first diode, and an insulating layer disposed on the first heat sink. In addition, the improved bridge rectifier includes a second heat sink disposed on the insulating layer. The second heat sink includes a base section including first and second areas, a second diode, and a diode receiving holes in the base section and receiving the second diode therein. The second heat sink also includes a plateau section disposed on the first area of the base section, and air passages disposed in and extending through the base and plateau sections. The improved bridge rectifier further includes connectors, connecting the first heat sink and the second heat sink together with the insulating layer disposed therebetween, a cover connected to the base section and covering the second area of the base section, and a capacitor connected to the cover and to the second heat sink.
