Tekwani, P. N., Auteur ; R. S. Kanchan, Auteur ; Gopakumar, K., Auteur |For a dual five-level inverter-fed induction motor (IM) drive, effects of DC-neutral currents on dc-link capacitor voltage fluctuations are analyzed in this paper. Operating limitations in achieving the dual task of common-mode voltage eliminati[...]

Tekwani, P. N., Auteur ; R. S. Kanchan, Auteur ; Gopakumar, K., Auteur |A current error space phasor based simple hysteresis controller is proposed in this paper to control the switching frequency variation in two-level pulsewidth-modulation (PWM) inverter-fed induction motor (IM) drives. A parabolic boundary for th[...]

Mondal, Gopal, Auteur ; Gopakumar, K., Auteur ; Tekwani, P. N., Auteur |The paper presents a five-level inverter scheme with reduced power circuit complexity for an induction motor drive. The scheme is realized by cascading conventional two-level and three-level neutral point clamped inverters in conjunction with an[...]

Malinowski, Mariusz, Auteur ; Gopakumar, K., Auteur ; Rodriguez, José, Auteur |Cascaded multilevel inverters synthesize a medium-voltage output based on a series connection of power cells which use standard low-voltage component configurations. This characteristic allows one to achieve high-quality output voltages and inpu[...]
