Rectifier assembly for parallel connection of diodes

Claim 1

A diode rectifier assembly comprising: a plurality of diodes, each diode having anode and cathode sides, a first means electrically connecting one of the anode and cathode sides of each of said diodes to one another, a second means electrically connecting the other of said anode and cathode sides of each of said diodes to one another, said second means including: a common conduction area defining a central electronically conductive area, a plurality of links extending radially from the common conduction area, each link having a predetermined area for regulating current flow through said predetermined area, said predetermined area delimiting a fuse which opens under predetermined conditions so as to disconnect an individual one of said plurality of diodes from said central conduction area, thereby permitting said rectifier assembly to operate even with failure of individual ones of said diode plurality, and a plurality of diode contact areas peripherally spaced about the common conduction area, each diode contact area engaging one of said anode and cathode sides of said diodes, each link interconnecting one of the diode contact areas and the common conduction area, said second electrically connecting means being integrally formed from a single material sheet, and pressure means engaging and applying pressure to the diode contact areas of said second electrically connecting means for holding the diode contact areas against one of said anode and cathode sides of said diodes and holding the other of said anode and cathode sides of said diodes against said first electrically connecting means, said pressure means maintaining mechanical and electrical contact between the anode and cathode sides of said diodes and respective ones of said first and said second electrically connecting means, and wherein each diode area is thermally conductive for providing thermal conduction from its associated diode to its associated link, the links have a positive coefficient of resistance, and the links have a cross-section providing greater electrical resistance than the contact areas.
