(Institute of Electrical and Electronics Engineers, 2019)In aerospace applications, a ground power unit has to provide balanced and sinusoidal 400 Hz phase-to-neutral voltages to unbalanced and nonlinear single-phase loads. Compensation of high-order harmonics is complex, as the ...
-
(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 ...
-
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 ...
-
(IEEE-Inst. Electrical Electronics Engineers, 2021)In this work, a continuous-control-set model predictive control (CCS-MPC) strategy, with a saturation scheme for protection, is presented for regulating the circulating currents of a modular multilevel matrix converter ...
-
(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 ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-07)In this paper a new control system for a 4-leg Matrix Converter (MC) feeding an isolated load is discussed. The proposed system is appropriate for wind-diesel schemes or any other application where a path for the circulation ...
-
(Elsevier, 2013)The Doubly-Fed Induction Generator (DFIG) is one of the most widely used generators for wind energy applications with more than 50% of installed Wind Energy Conversion Systems (WECS) using this variable speed technology. ...
-
(Universidad de Chile, 2018)Hoy en día, la construcción de maquinaria y plantas industriales exigen soluciones de accionamiento con un diseño flexible y escalable. En sectores industriales como la petroquímica, la minería, la generación de energía, ...
-
(IEEE-Inst Electrical Electronics Engineers, 2022)Distributed control of modular multilevel converter (MMC) submodules (SMs) offers several potential benefits such as flexibility, scalability, and modularity. In this approach, low-level control tasks, such as capacitor ...
-
(IEEE, 2021)In a hybrid modular multilevel converter (MMC), capacitor voltage balance between the Full-Bridge Sub-Modules (FBSMs) and Half-Bridge Sub-Modules (HBSMs) is only possible when the arm currents are bipolar. For a grid-connected ...
-
(IEEE, 2015)Delayed signal cancellation is one of the methods used to separate the negative- and positive-sequence components in unbalanced systems. In this letter, a DSC methodology with fast convergence time is proposed and it ...
-
(Universidad de Chile, 2021)Esta tesis presenta 2 estrategias de control para asegurar el balance de las celdas de un conversor modular multinivel hibrido, que opera en sobremodulación. Se desarrolla y presenta un control desacoplado para regular ...
-
(Elsevier, 2013)Generators working with variable speed, rather than fixed speed, have many advantages, which are well documented in the literature. Higher efficiency, better power to size ratio and less mechanical stress in the system ...
-
(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 ...
