Abstract
This research focuses on the suitability of multi-level inverters for controlling induction motors, particularly in high voltage and power applications. Multi-level inverters offer advantages such as reduced voltage stress on switching devices and decreased harmonic distortion in the output. The study evaluates the performance of two-level and three-level voltage source inverters using sinusoidal pulse width modulation (SPWM) and space vector pulse width modulation (SVPWM). The induction motor serves as the load to demonstrate the effectiveness of the proposed inverter system. The project analyzes the harmonic content in the inverter output voltage and studies the speed of the induction motor under various loads in the MATLAB/Simulink environment. The simulation results highlight the effectiveness of the suggested inverter system by significantly reducing overall harmonic distortions in the output voltage through the application of different pulse width modulation techniques. Additionally, the study showcases the inverter's ability to regulate the speed of the induction motor at different loads effectively. Overall, this investigation demonstrates the potential of multi-level inverters as a reliable solution for controlling induction motors in high-power applications, offering improved voltage waveforms and enhanced motor performance by minimizing harmonic distortions.
