Journal ArticleDOI
Multilevel inverters for low-power application
TL;DR: In this paper, the effect of clamping diodes in the diode-clamped multilevel inverters played an important role in determining its efficiency and the trade-off analysis was performed to quantify the suitability of multi-level inverters in low power applications.
Journal ArticleDOI
A Hybrid Multilevel Inverter Topology for an Open-End Winding Induction-Motor Drive Using Two-Level Inverters in Series With a Capacitor-Fed H-Bridge Cell
TL;DR: The proposed inverter topology for open-end winding induction-motor drive can be operated as a three-level inverter for full modulation range, in case of any switch failure in the capacitor-fed H-bridge cell, to increase the reliability of the system.
Journal ArticleDOI
A Dual Seven-Level Inverter Supply for an Open-End Winding Induction Motor Drive
TL;DR: The proposed power circuit structure is modular and therefore suitable for fault-tolerant applications, and can be operated during fault conditions in a five-level or a three-level inverter mode, with preserved CMV elimination and DC-link capacitor voltage balancing, within a reduced modulation range.
Journal ArticleDOI
Fast Direct Torque Control of an Open-End Induction Motor Drive Using 12-Sided Polygonal Voltage Space Vectors
C. Patel,Rajeevan P. P. A. Day,Anubrata Dey,Rijil Ramchand,K. Gopakumar,Marian P. Kazmierkowski +5 more
TL;DR: In this paper, a direct torque control (DTC) algorithm using a 12-sided polygonal voltage space vector is proposed for a variable speed control of an open-end induction motor drive.
Journal ArticleDOI
A Space-Vector-Based Hysteresis Current Controller for a General n-Level Inverter-Fed Drive With Nearly Constant Switching Frequency Control
TL;DR: A current-error space-vector-based hysteresis current controller for a general n-level voltage-source inverter (VSI)-fed three-phase induction motor (IM) drive is proposed here, with control of the switching frequency variation for the full linear modulation range.
