Abstract :
CONVENTIONAL METHODS of calculating rectifier voltage regulation are valid only if the angle of overlap is less than 360 degrees divided by the number of phases. At larger angles of overlap an inherent delay angle, introduced by a-c reactance common to two or more simple rectifiers, reduces the direct voltage and thereby increases the voltage regulation. This phenomenon has been described in two papers,1, 2 recently presented to the Institute, in which curves and equations for determining voltage regulation of 6-phase rectifiers were given. Two earlier articles5, 4 recognized the phenomenon in 6-phase circuits.
