Comparitive Analysis of Induction Motor Drive with Vector Control

Abstract

Induction machines are the most generally utilized machines for commercial applications. They are mainstream for utilization as modern drives on account of its high efficiency, great power factor and greatly rugged nature. In this paper, voltage source inverter and multilevel inverter are utilized to excite drives. Here multilevel inverter gives about sinusoidal voltage with less harmonic distortion in voltage and current waveforms compared with voltage source inverter. The advancement of vector control methods upgraded the execution the performance and speed control in motor drives. Here we propose IFOC control for the induction motor drive. The rotor flux and torque producing current parts are decoupled by conversion to d-q reference edge and controlled utilizing a PI controller. A SPWM based inverter topology is utilized for VSI and for MLI, SPWM with Phase Disposition PWM system is utilized to encourage the induction motor drive. In this paper we have classified and analyzed distinctive parameters of Multi level inverter and Voltage source inverter encouraged IM drive with vector control. The execution of the machine is examined by plotting the aspects under distinctive working conditions.
