Abstract: This paper shows a double three phase open end winding enlistment motor drive. The drive comprises of a three phase enlistment machine with open stator phase windings and double bridge inverter provided from a solitary DC voltage source. To accomplish multi-level output voltage waveforms a floating capacitor bank is utilized for the second of the double bridges. The capacitor voltage is directed utilizing redundant switching states at half of the fundamental dc link voltage. This specific voltage proportion (2:1) is utilized to make a multi-level output voltage waveform with three levels. An adjusted modulation plot is utilized to enhance the waveform nature of this double inverter. This paper additionally analyzes the misfortunes in double inverter system interestingly with single sided three-level NPC converter.
