Speed Control Simulation for Induction Motor by Multi Level VSI-Fed to Analyse Current Harmonics and Selective Harmonics Elimination

This study presented the simulation studies on closed-loop speed control for 3-phase induction motor by applying V/F method. This induction motor is fed by three and five-level diode clamped Voltage Source Inverter (VSI). Sinusoidal pulse with modulation technique is used to control inverter power switches. The harmonics of phase current is analysed. Then selective harmonics is eliminated by comparison of sine wave with modified triangle carrier. In this method, we could eliminate selective harmonics with no need to complex equations solving. In this study, by present the quasi triangle carrier Total Harmonic Distortion (THD) is decreased.
