dc.description.abstractThe demand for the induction motor is ever-growing day by day because of its robustness, high efficiency, and low cost over other motors. With the increasing demand for speed control of induction motor, a necessity arises to find an efficient motor controlling method. PWM techniques are an efficient method used to vary both the voltage and frequency within an inverter. A comparative study of five different PWM techniques of a three-phase voltage source inverter for the best induction motor drive performance is presented in this paper using MATLAB/Simulink software simulation. Sinusoidal PWM, Sixty-Degree PWM, Trapezoidal PWM, Third Harmonic Injected PWM, Space Vector PWM etc. techniques are demonstrated here. Induction motor characteristics like rotor speed, rotor steady speed obtaining time, rotor current, stator current & electromagnetic torque etc. along with inverter output characteristics like voltage THD%, current THD% etc. were observed by varying modulation index, carrier frequency, and loading condition of the induction motor drive. The simulation result shows that the Third Harmonic Injected PWM (THIPWM) technique exhibits the best induction motor drive performance compared to other PWM techniques.en_US
