Abstract
Abstract A rectifier for an electric generator, set up in a three-phase full-wave circuit, the metal case of which is in two parts each having on the joint surface an insulating base with built-in connecting tags for application of three-phase voltage to the semiconductor elements arranged inside each part of the case. The bolts holding together the cast parts simultaneously serve as d.c. output terminals for the rectifier and fasten the rectifier to a generator.

Claim 1
Independent Claim
125 words
A rectifier for an electric generator, set up in a threephase full-wave circuit, comprising: a split metal case made up of two parts; semiconductor elements arranged in one of the parts of said split case and connected to it with their P-regions; other semiconductor elements arranged in the other part of said split case and connected to it with their N-regions; insulating bases fastened each to the joint surface of the two parts of said case; connecting tags built into said insulating bases and intended for application of three-phase voltage to all of the said semiconductor elements; two bolts holding together the two said parts of the case and fastening the rectifier to the generator, which also serve as d.c. output terminals for the rectifier.
