Experimental development of a hysteresis modulated NPC inverter

Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004
The paper presents the laboratory prototype realization of a system constituted by an IGBT based neutral point clamped (NPC) inverter, a driver stage and a digital control circuit board. A hysteresis control technique, developed by authors in previous papers, suitable for the current control of the NPC inverter is implemented in the control system. The

A single-phase asymmetrical NPC inverter topology

2016 13th International Conference on Power Electronics (CIEP), 2016
This paper presents a topology and a modulation scheme for a single-phase multi-level inverter referred as asymmetrical NPC. The proposed topology is formed by two legs, namely, a NPC and a standard two-level leg, where The NPC leg allows access to the middle point of the DC source.

SVM algorithm of three-level NPC inverter

2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008
On the basis of presenting the principles of space vector modulation (svm) of three-level neutral point clamped (NPC) inverter, an approach to implementation of SVM is proposed. The dwell times of vectors are calculated according to the volt-second balancing. A triangle is adopted to compare with three switching points.

FCS-MPC for Three-Level NPC Inverter-Fed SPMSM Drives Without Information of Motor Parameters and DC Capacitor

IEEE transactions on industrial electronics (1982. Print)
The conventional finite-control-set model-predictive control (FCS-MPC) suffers from poor robustness against model mismatches. This article presents an improved FCS-MPC with a reconstructed mathematical model to predict current variations without using a ...

Transformerless Three Phase NPC Inverter with Reduced Switches

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
In a photovoltaic grid connected system, the attenuation of the common mode voltage is one of the main issues. Many single phase inverters have been proposed to improve the common mode characteristic. However, few studies have been focused on the topological improvement for common mode behavior of the three phase inverter. This paper proposed two types

Predictive voltage controller for T-type NPC inverter

2016 IEEE Region 10 Conference (TENCON), 2016
The objective of this paper is to present a new method to control the TNPC inverter with output LC filter based on the Predictive controller. Furthermore, the balance voltage capacitors is also obtained with the proposed method. The model of the system is used to establish the equations, which can be applied to calculate the future values of the load ...
