Analysis of reactive power strategies in HVDC-connected wind power plant clusters
(2017-12)
Article
Accés obert© 2017 John Wiley & Sons, Ltd. Offshore wind power plants (WPPs) built near each other but far from shore usually connect to the main grid by a common high-voltage DC (HVDC) transmission system. In the resulting decoupled ... -

Control to reduce leading current in a Shunt Hybrid power filter
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Text en actes de congrés
Accés obertThe main drawback of Shunt Hybrid Filters is the need of leading current injection. This paper describes a strategy to reduce the leading current in a three phase four wires LC coupled parallel hybrid filter for harmonics ... -
Current-balancing technique for interleaved voltage source inverters with magnetically coupled legs connected in parallel
(Institute of Electrical and Electronics Engineers (IEEE), 2015-03-01)
Article
Accés obertConnecting legs in parallel in a voltage source inverter is a way to increase the output current and, thus, its rated power. The connection can be made using either coupled or uncoupled inductors, and achieving an even ... -
Direct current control for grid-connected diode-clamped inverters
(Institute of Electrical and Electronics Engineers (IEEE), 2017-04-01)
Article
Accés obertThe accurate control of the line current, robust and dynamic behavior even under distorted grids and other system faults are the most important requirements for grid-connected inverters. Applying direct current control to ... -
Estudio comparativo entre el control en el marco de referencia αβ y el control predictivo basado en el modelo dinámico del sistema para un filtro activo en paralelo
(Universitat Politècnica de Catalunya, 2019-01-31)
Projecte Final de Màster Oficial
Accés obert[CASTELLÀ] El uso de elementos electrónicos en las aplicaciones industriales está en constante crecimiento debido a las ventajas que éstos presentan en términos del control del comportamiento de sistemas. Dicho esto, el ... -

Model-based control for a three-phase shunt active power filter
(Institute of Electrical and Electronics Engineers (IEEE), 2016-03-10)
Article
Accés obertThis paper presents a robust model-based control in natural frame for a three-phase shunt active power filter. For the proposed control method a linear converter model is deduced. Then, this model is used in a Kalman ... -
Passivity-based analysis and performance enhancement of a vector controlled VSC connected to a weak AC Grid
(Institute of Electrical and Electronics Engineers (IEEE), 2021-02)
Article
Accés obertDespite attempts to increase the active power capability of vector-controlled voltage source converters (VSCs) connected to very weak grids, the interaction between the control dynamics and physical system is not completely ... -
Reducing the cogging torque effects in hybrid stepper machines by means of resonant controllers
(Institute of Electrical and Electronics Engineers (IEEE), 2018-06-11)
Article
Accés obertPermanent magnet machines are not free from the interaction between magnets and the stator and rotor slots, which causes an undesired disturbing torque. Such cogging or detent torque is especially larger with salient pole ... -
Study of the exposure to time-varying electric field in the ESEIAAT UPC School
(2016)
Comunicació de congrés
Accés obertIn this paper, the level of exposure to time-varying electric fields up to 18 GHz in the main building of the ESEIAAT School at the Universitat Politècnica de Catalunya, located in the Terrassa Campus (Barcelona, Spain), ... -
The Input-output equivalent sources method for fast simulations of distributed nonlinearities in bulk acoustic wave resonators and filters
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Article
Accés obertThis work presents a new method to analyze weak distributed nonlinear effects, with focus on the generation of harmonics (H) and intermodulation products (IMD) in bulk acoustic wave resonators and filters composed of them. ... -
