Modular Multilevel Converter Based Topology for High-Speed, Low-Voltage Electric Drives
(IEEE-Inst. Electrical Electronics Engineers, 2020)
The increasing demand for higher power density and more efficient electric drives, in particular, from the automotive industry, has pushed engineers investigating new solutions. Recently, wide bandgap devices have been ...
A vector control strategy to eliminate active power oscillations in four-leg grid-connected converters under unbalanced voltages
(IEEE, 2020)
The problems associated with active power oscillations (APOs) in grid-connected converters are well-known. Imbalances in the grid usually produce double-frequency oscillations in the dc-link voltage and current which could ...
A simplified Space-Vector modulation algorithm for four-leg NPC converters
(IEEE Inst Electrical and Electronic Engineering Inc., 2017)
To interface generation sources and loads to fourwire distribution networks it is important to use power converters and modulation methods, which provide high performance, flexibility, and reliability. To achieve these ...
Design and implementation of a low-cost real-time control platform for power electronics applications
(MDPI, 2020)
In recent years, different off-the-shelf solutions for the rapid control prototyping of power electronics converters have been commercialised. The main benefits of those systems are based on a fast and easy-to-use environment ...
Control of wind energy conversion systems based on the modular multilevel matrix converter
(IEEE Institute of Electrical and Electronics Engineers, 2017)
The nominal power of single wind energy conversion systems (WECS) has been steadily increasing, now reaching power ratings close to 10 MW. In the power conversion stage, medium-voltage power converters are replacing the ...
Control of a back-to-back converter as a power transfer system using synchronverter approach
(The Institution of Engineering and Technology, IET, 2018-02-21)
This study presents an innovative approach where both sides of a back-to-back (BtB) system are controlled using the synchronverter approach, allowing to control the power transfer through the converters as it would be in ...
Self-Tuning Resonant Control of a Seven-Leg Back-to-Back Converter for Interfacing Variable-Speed Generators to Four-Wire Loads
(IEEE, 2015)
This paper considers the control of a seven-leg back-to-back voltage source inverter arrangement, feeding a four-wire load from a three-phase permanent-magnet synchronous generator (PMSG) operating at variable speed. The ...
Analysis and Experimental Validation of Control Systems for Four-Leg Matrix Converter Applications
(IEEE, 2012-01)
Matrix Converters (MCs) have some advantages when compared to conventional back-to-back PWM voltage source converters. The converter may be considered more reliable and it can be smaller because the bulky dc capacitors are ...
Continuous set model predictive control for energy management of modular multilevel matrix converters
(IEEE-INST Electrical Electronics Engineers, 2022)
The modular multilevel matrix converter (M3C) is an
ac to ac power converter composed of 9 arms and is proposed
for high power applications such as motor drive and wind energy
conversion systems. Energy Control of the ...
An integrated converter and machine control system for MMC-based high-power drives
(IEEE, 2019)
The modular multilevel converter (MMC) is a promising topology for high-power drive applications. However, large voltage fluctuations can be produced in the floating capacitors when the machine operates with high stator ...
