Abstract

The rectifier structure comprises a plurality of diodes including opposed first and second terminals. A plate electrically connects the first terminals to one another. A retainer locates the diodes on the plate. A plurality of individual links including an outer end portion, an inner end portion, and a fuse portion therebetween are located on the retainer such that the outer end portion of each link is in contact with the second terminal of a respective diode. A washer is in contact with the inner end portion of each link for electrically connecting the second terminals to one another. The links provide fuses for disconnecting the diodes from the washer when excessive current flows through a diode.
