Comparative analysis of close loop three level voltage source inverter using sinusoidal Pulse Width Modulation and Third Harmonic Injection method for different loads

This paper presents a comparative analysis of Voltage Source Inverter using Sinusoidal Pulse Width Modulation Method and Third Harmonic Injection Pulse Width Modulation Method in Three level inverter for different loads with LC filter. In this paper designed the Simulink model of Inverter and Induction motor. All above technique is used to reduce the Total Harmonic Distortion (THD) or the power quality on the AC side of the Inverter. Results are analyzed using Fast Fourier Transformation (FFT) analysis for looking the Total Harmonic Distortion. In this paper the LC low pass filter is connected to the output of the Three level inverter to get the less harmonic in the supply current. All simulation are performed in the MATLAB Simulink 2014.
