Fault-Tolerant DTC Technique for Five-phase Three-Level NPC Inverter-fed Induction Motor Drive with an Open-Phase Fault

European Conference on Cognitive Ergonomics, 2019
The operation and control of multiphase induction motor drive under faulty condition is a big challenging task in the present day. For this, the direct torque control (DTC) technique has been proposed recently to a five-phase two-level (FPTL) inverter ...

Base/gate drive suppression methods for NPC inverter legs

Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 2002
The base/gate drive suppression methods for the voltage source inverter leg are those which suppress base/gate drives of either of the two switching devices of the leg. These methods have the merits that they do not have the conventional dead time problem, raise the reliability of the leg, and others.

Three-phase NPC inverter using three-phase coupled inductor

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
A new NPC three-phase inverter with three-phase coupled inductor is presented in this paper. Initially the power stage diagram is shown and discussed. Their main characteristics are described and the more relevant waveforms, generated by simulation, are shown. Next, the employed modulation and converter operation are discussed and some relevant figures

The Research and Simulation of Three-Level NPC Inverter

2016
Compared with the commonly used sine-wave pulse width modulation (SPWM) method, the space vector pulse width modulation (SVPWM) method has higher utilization rate of DC voltage and smaller output waveform distortion. This paper describes the basic principle and control algorithm of three-level SVPWM.
