This paper describes some techniques to improve the output waveform quality of multilevel inverts fed-indction machines. The investigated topologies are the diode-clamped and series-connection of H-bridges. Thesetechinques are based on an unequal dc-voltage supplyng. The multicarrier-based pulse width modulation techniques applied to the control of these inverters is also investigated.
