Abstract
A diode rectifier assembly includes a plurality of diodes having an anode and cathode sides. A plate electrically connects one side of the diodes while a current-regulating plate connects the other side of the diodes. The current-regulating plate includes a plurality of diode contact areas, a common conduction area and a plurality of links, each link electrically interconnecting one of the diode contact areas and the common conduction area. Each diode contact area connects a link to a diode, the links have predetermined areas for regulating current flow through associated diodes. The links have positive coefficient of resistence, and each diode contact area is thermally conductive, providing thermal connection from its associated diode to its associated link. The diode contact areas are held against the diodes by a resilient ring of insulating material. The links provide fuses for disconnecting diodes from the common conduction area when excessive current flows in a diode.
