Abstract 
This paper introduces a new method to track the saliency of motor fed by a multilevel inverter through
measuring the dynamic current response of the motor line currents due the IGBT switching actions.
The method uses only the fundamental PWM waveform (i.e there is no modification to the operation
of the multilevel inverter) similar to the fundamental PWM method proposed for a 2-level inverter.
Simulation results are provided to demonstrate the performance of the complete sensorless speed 
control of a PM motor driven by such a converter over a wide speed range. Finally the paper
introduces a comparison between the 2-level inverter and the multilevel inverter in terms of the
reduction of the Total Harmonic Distortion (THD) using the fundamental PWM method in both cases.
