19 October 1987 Four Quadrant Speed Control Of Induction Motor By Unrestricted Frequency Changer
Author Affiliations +
This speed control system uses an AC/AC direct converter as driver, featuring that its output frequency margin goes from 0 to 127 Hz. Four quadrant speed control is entirely done by a microcomputer and calculation of the time functions of each power circuit bidirectional static switches (PCBSS) is done in real time, obtaining a high flexibility, high resolution, very trustworthy and drive circuit least components system.
