Dual Inverter Control Strategy for Open Ended Winding Motor Drive Applications

Authors(2) :-K. Hemadri, Dr. S. Mallikarjunaiah

This paper shows a dual three stage open end winding inductionmotor drive. The drive comprises of a three stage induction machine with open stator stage windings and dual extension inverter provided from a single DC voltage source. To accomplish multi-level output voltage waveforms a floating capacitor bank is utilized for the second of the dual extensions. The capacitor voltage is controlled utilizing excess switching states at half of the principle dc interface voltage. The primary controller (master controller) is designed as a Fuzzy logic controller. This specific voltage proportion (2:1) is utilized to make a multi-level output voltage waveform with three levels. An altered modulation conspire is utilized to enhance the waveform nature of this dual inverter. This paper likewise thinks about the losses in dual inverter system conversely with single sided three-level NPC converter. At last, point by point simulation and experimental comes about are exhibited for the motor drive working as an open loop v/f controlled motor drive and as a shut loop field orientedmotor controller.
