Sangita Gohil | Priyal Bhavsar | Devanshi Gandhi

Abstract: In this paper, different types of speed control methods for the single phase induction motor are described. This research paper review speed control of single phase induction motor by means of V/F control, PWM technique and direct flux and torque control. In V/F control, maintain ratio V/F constant. Different types of PWM strategies have been used in speed control of SPIMDs [sinusoidal pulse induction motor drive], most widely sinusoidal PWM & space vector PWM strategies [7]. The proposed paper describes the several PWM strategies with an AC chopper to control the speed of single phase induction motor and reduce the harmonic present in motor current [2]. PWM technique has been used to operate the power electronics switches (IGBT) of an AC chopper. IGBT is used as power switching device because of having advantage of other power switch (MOSFET, Thyristor ext). The voltage Controller achieves an almost linear response and the motor speed is smoothly regulated within the full dynamic range of the control input [3]. Direct flux and torque control (DTC) based speed control of induction motor (IM) drive and effect of flux and torque Hysteresis band amplitude on this strategy is presented. This scheme is simple and provides a good dynamic response, but the major problem associated with this DTC drive is high torque along with stator flux ripples. The direct torque control of induction machine is based on the use of two hysteresis controllers [8].
