A comparative study of Total Harmonic Distortion in Multi level inverter topologies

T. Prathiba, P. Renuga


This paper presents a detailed harmonic analysis in terms of Total Harmonic Distortion (THD) for different power circuit topologies of multi level inverter fed induction motor drives. The most common multilevel inverter topologies are the neutral-point-clamped inverter (NPC), flying capacitor inverter (FC), and cascaded H-bridge inverter (CHB). This work is to analyze the performance of all the power circuit topologies of multilevel inverter with various multi carrier PWM control techniques. Simulation and results shows that the superiority of these inverters over two-level pulse width modulation based inverter fed drives.

Keywords: Medium-voltage drives, Multi Carrier PWM, Multi level inverter, Induction motor drives.
