three-phase gleichrichterschaltung with zwu00f6lfpulsgleichrichtern

摘要

The rectifier stage (18) comprises: - an autotransformer (40) with a twelve-phase rectification; - two diffusers (50a, 50b) each of its input connected to three distinct stages of the autotransformer (40); - two interphase inductors (51a, 51 b); and - a filtering stage (54) which receives as input the mid-points of the two interphase inductors (51a, 51 b). the two interphase inductors (51a, 51 b) comprise a core which is common (52) defining a magnetic circuit, and all the windings of the two interphase inductors (51a, 51b) are wound on this core is common to their magnetic coupling.
