VTechWorks staff will be away for the Thanksgiving holiday beginning at noon on Wednesday, November 22, through Friday, November 24, and will not be replying to requests during this time. Thank you for your patience, and happy holidays!
The output voltage of controlled polyphase rectifiers
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.
