A multilevel modular dc-dc converter topology
Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Andrade, Iván; Riedemann, Javier; Pesce, Cristián; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Elsevier (2017)A multilevel modular DC-DC power conversion topology based on cascaded H-Bridge converters in a double П configuration is presented. The topology is intended to interconnect large power DC networks. A two level control ... -
Analysis of the Performance of MMC Under Fault Conditions in HVDC-Based Offshore Wind Farms
Vidal-Albalate, Ricardo; Beltran, Hector; Rolán Blanco, Alejandro; Belenguer Balaguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (IEEE (2016-04)This paper analyzes the behavior of a modular multilevel converter-high-voltage direct-current (MMC-HVDC)-connected offshore wind power plant (WPP) during dc faults. For that purpose, detailed models of the dc cable, ... -
Efficient model for modular multi-level converter simulation
Vidal-Albalate, Ricardo; Belenguer Balaguer, Enrique; Beltran, Hector; Blasco-Gimenez, Ramon Elsevier (2016)Detailed models of modular multi-level converters (MMCs) are cumbersome for electromagnetic transient simulation programs because of their high number of components which involve large simulation times. In this work, the ... -
Embedded Real-Time Simulator for Sensorless Control of Modular Multi-Level Converters
Tormo, Daniel; Vidal-Albalate, Ricardo; IDKHAJINE, LAHOUCINE; Monmasson, Eric; Blasco-Gimenez, Ramon MDPI (2022-02-25)This paper suggests the application of an embedded real-time simulator (eRTS) in the context of voltage–sensorless control of a modular multilevel power converter (MMC). This eRTS acts as an observer and ensures digital ... -
Fault-tolerant strategies in MMC-based high power magnet supply for particle accelerator
Colmenero Moratalla, Manuel; Vidal-Albalate, Ricardo; Blanquez Delgado, Francisco R.; Blasco Giménez, Ramón Elsevier (2023)Many particle accelerators require to supply chains of magnets with high quality, high magnitude, cycling currents. To do this, the power converters need to provide high output voltages, reaching in some cases tens of ... -
Modeling and enhanced control of hybrid full bridge–half bridge MMCs for HVDC grid studies
Vidal-Albalate, Ricardo; Forner, Jaume MDPI (2020-01-01)Modular multilevel converters (MMCs) are expected to play an important role in future high voltage direct current (HVDC) grids. Moreover, advanced MMC topologies may include various submodule (SM) types. In this sense, ... -
Multivariable phase-locked loop free strategy for power control of grid-connected voltage source converters
Díaz-Sanahuja, Carlos; Peñarrocha-Alós, Ignacio; Vidal-Albalate, Ricardo Elsevier (2022-05-17)A multivariable control strategy in a reference frame for grid-connected voltage source converters (VSCs) without using a phase-locked loop (PLL) is presented in this paper. First, common VSC controls such as vector current ... -
Protection Strategies for the Connection of Diode Rectifier-Based Wind Power Plants to HVdc Interconnectors
Martínez-Turégano, J.; Vidal-Albalate, Ricardo; Añó-Villalba, Salvador; Bernal-Perez, Soledad; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (2020-10-05)The connection of diode rectifier (DR)-based wind power plants (WPPs) to existing or planned high-voltage dc (HVdc) interconnectors can lead to important savings on cost and system robustness. Since the DR station usually ... -
Sizing and Short-Circuit Capability of a Transformerless HVDC DC-DC Converter
Vidal-Albalate, Ricardo; Soto Sánchez, Diego; Belenguer, Enrique; Peña, Rubén; Blasco-Gimenez, Ramon Institute of Electrical and Electronics Engineers (2020-01-15)This work aims at optimizing the converter design of the double-T MMC DC-DC converter in terms of transmitted power per submodule and also in terms of transmitted power per silicon area, while, at the same time, providing ...
