A new modulation method for multilevel converters [PDF]

open access: yes, 2016
This paper presents a simple method for modulation in multilevel converters, which is hardly affected with the number of levels. The method is based on a simple graph, whose x-axis is directly related to the extra degree of freedom associated with ...

Space Vector Modulation Method-Based Common Mode Voltage Reduction for Active Impedance-Source T-Type Inverter

open access: yesIEEE Access, 2022
In recent years, many pulse width modulation techniques have been explored for three-level impedance-source inverters. Among them, a space vector modulation (SVM) technique using upper/lower shoot-through (UST/LST) insertion provides high voltage gain ...

Space vector modulation technique for 3-level NPC converter with constant switching frequency [PDF]

open access: yes, 2016
This paper presents a simple Space Vector Modulation (SVM) methodology for a three-level NPC converter. Nearest three vectors (NTV) and corresponding duty cycles are deduced through simple generic mathematical expressions. Extra degrees of freedom of NPC

A Modified Neutral-point Voltage Control Strategy for Three-level Inverters Based on Decomposition of Space Vector Diagram

open access: yesCES Transactions on Electrical Machines and Systems, 2022
Capacitor voltage imbalance is a significant problem for three-level inverters. Due to the mid-point modulation of these inverter topologies, the neutral point potential moves up or down depending on the neutral point current direction creating ...

Performance of Neutral Point Clamped Five Level Inverter Using Space Vector Modulation Control Fed by DPC-VF-SVM Rectifier

open access: yesWSEAS TRANSACTIONS ON POWER SYSTEMS, 2021
The purpose of this paper is to develop a control and regulation method for the input DC voltage of a five level neutral point clamping (NPC) inverter feeding a induction motor. In this context, the authors propose in the first part, the control strategy of three-phase pulse width modulation rectifier, they propose the virtual flux-based direct control
