ANALYSIS AND SIMULATION OF DISCRETE SPEED A. C. MOTOR DRIVES
Abstract
The thesis presents some results of the investigation into the problem of discrete speed control of an induction motor. Three different systems have been studied, the first system consists of a three-phase induction motor fed by a single-phase power supply using a cycle-skipping inverter, the second system is a three-phase induction motor fed by two-phases of a three-phase power supply, using a new cycle-skipping inverter which has been introduced for the first time in this thesis, and finally the technique is extended to a system of a six-phase induction machine fed by two cycle-skipping inverters using a two-phase power supply. Steady state performance of the system has been studied using the state-variables technique, also simulation of the system is performed on the analog computer. The results obtained are summarized.
