Abstract
Induction motor is cheap, rugged, reliable, and long-lasting compared to the dc motor. It requires little maintenance because of the absence of commutator and brushes, and can be operated in explosive and contaminated surroundings. The volume, weight, and inertia are lower, while the operational speed, voltage and power can be made higher than in dc motors. The electric drive systems used in industrial applications are increasingly required to meet higher performance and reliability. Hence about ninety percent of all industrial motor applications are induction motors. The load on induction motor is not constant, and varies as per load requirement. So speed and torque must change as per load. This paper investigates variable frequency drive of induction motor, employing power semiconductor converters. The speed and torque of the induction motor are controlled by either the stator supply frequency ( ), or stator voltage ( ). Advances in power electronics has made variable frequency drives popular. The converters used here are controlled rectifier and voltage source inverter (VSI). Controlled rectifier is used to provide controlled dc input voltage to the inverter, which converts the dc voltage to variable frequency ac voltage, feeding the induction motor. So the control scheme is an ac-to-ac converter with a dc link.
