摘要

The inverters and converters are introducing harmonics due to its properties. The most commonly used load for a three-phase line is a motor for industrial applications. The major problem of linear and nonlinear loads like motors are heats up due to harmonics introduced in the line voltage. The analysis of total harmonic distortion and magnitude of harmonics at the output of the three-phase inverter drive is carried out in this work. The simulation is obtained using MATLAB/Simulink. A traditional three-level inverter and three-level inverter with C-type filter are constructed and simulated. The circuits are built using IGBTs as switches and pulse generators are used to provide the gating signal to the switches. A three-phase asynchronous machine is provided with the same parameter of actual motor. An FFT analysis is done to obtain magnitudes of harmonics at the inverter output voltage, and the obtained results are compared.
