Testing method for Zener/rectifier diodes for a motor vehicle's generator easily recognizes the type of diode by measuring quiescent current and capacity

摘要

A six-pulse rectifier bridge circuit (1) converts phase voltages (U,V,W) into a direct current voltage attached to terminals (B+,B-) and has a positive half bridge with positive Zener diodes (4-6) and a negative half bridge with negative Zener diodes (7-9) so as to maintain protection from excess voltage during a sudden drop in load.
