Co-Simulation of Three Phase Induction Motor Controlled by Three Level Inverter

Abstract

The main objective of this research is to build and control a three-phase induction motor using the ANSYS Simplorer and Maxwell2D program to obtain a high-quality sinusoidal voltage profile with little distortion and therefore low harmonics. A control circuit has been proposed using diodes to control the motor speed by v/f method. This method depends on the principle of changing the source voltage in addition to the frequency in a fixed ratio to obtain the best working conditions and the best characteristics of the motor with the least possible losses. The modeling results show the effectiveness of the proposed circuit in controlling the motor speed effectively and enhancing the motor performance by reducing losses when using traditional methods of controlling the motor speed. The effectiveness of the control system is verified by analyzing the results using the ANSYS program.
