The output voltage of controlled polyphase rectifiers

Abstract

The controlled polyphase rectifiers in current use employ delayed firing in some degree to obtain voltage control. Delayed firing increases the harmonic content of the rectified voltage to such an extent that the harmonics determined without firing delay are insignificant. The harmonic content which exists is displayed in the results of this A investigation. These results are the foundation for analyzing the suitability of a particular rectifier circuit for a given application.
