Study of "chopper/inverter" AC drives using gate turn-off thyristors"

Abstract

This report examines the study of variable speed induction motor drives. It includes a comparison of the various systems available and specifically examines the present state of the art of power electronics used in drives. The various mathematical methods used to derive the parameters values are also examined. Two specific control methods,the Voltage/Frequency and vector controlled methods,are designed,constructed and then compared.The vector control method was not however constructed satisfactorly and in view of the limited time scales it was decided to leave the complete development of this aspect for further work.
