The emergence of multilevel converters has been in increase since the last decade These new types of converters are suitable for high voltage and high power application due to their ability to synthesize waveforms with better harmonic spectrum Numerous topologies have been introduced and widely studied for utility and drive applications Amongst these topologies, the multilevel cascaded inverter was introduced in Static Var compensation and drive systems This paper presents a comparison of PWM (Pulse Width Modulation) strategies for multilevel cascaded and classical inverters applied to the vectorial control of asynchronous machine in order to ensure an efficient utilization and better harmonic spectrum A modelling and control strategy of a three phase multilevel cascaded inverter is also investigated Computer simulation results using MATLAB progra
