An Adaptive Control System for Three-Phase Photovoltaic Inverters Working in a Polluted andVariable Frequency Electric Grid

González Espín, Francisco José; Gabriel Garcerá; Patrao Herrero, Iván; Figueres Amorós, Emilio (Institute of Electrical and Electronics Engineers (IEEE), 2012)

Theproportional+resonant (PR) controller has been proposed in the past as a suitable method to control the current generated by the grid-connected photovoltaic voltage source inverters. Due to the fact that information ...
An Adaptive Digital Control Technique for Improved Performance of Grid Connected Inverters

González Espín, Francisco José; Patrao Herrero, Iván; Figueres Amorós, Emilio; Gabriel Garcerá (Institute of Electrical and Electronics Engineers (IEEE), 2013)

Grid connected voltage source inverters may be controlled in the stationary reference frame by means of the infinite impulse response (IIR) P+Resonat regulator. This regulator is able to correctly track fixed frequency ...
An adaptive synchronous-reference-frame phase-locked loop for power quality improvement in a polluted utility grid

González Espín, Francisco José; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

The proper operation of grid-connected power electronics converters needs using a synchronization technique to estimate the phase of the grid voltage. The performance of this synchronization technique is related to the ...

Measurement of the Loop Gain Frequency Response of Digitally Controlled Power Converters

González Espín, Francisco José; Figueres Amorós, Emilio; Garcerá, Gabriel; González-Medina, Raúl; Pascual Molto, Marcos (Institute of Electrical and Electronics Engineers, 2010)

[EN] The study of the loop gain frequency response in a power converter is a powerful tool commonly used for the design of the controllers used in the control stage. As the control of medium- and high-power electronic ...
Modelado y Control de Rectificadores Activos Trifásicos con Capacidad de Regeneración de Energía

González Espín, Francisco José (Universitat Politècnica de València, 2011-11-28)

En la presente tesis de máster se aborda el modelado y control de rectificadores activos trifásicos con con alto factor de potencia y capacidad de regeneración de energía. Partiendo del modelo de conmutación del convertidor, ...
Robust model-following control of parallel UPS single-phase inverters

Pascual Molto, Marcos; Garcerá Sanfeliú, Gabriel; Figueres Amorós, Emilio; González Espín, Francisco José (Institute of Electrical and Electronics Engineers (IEEE), 2008-08)

This paper presents a robust control technique applied to modular uninterruptible power-supply (UPS) inverters operating in parallel. When compared to conventional proportional-integral (PI) control, the proposed technique ...
Sensitivity Study of the Dynamics of Three-Phase Photovoltaic Inverters With an LCL Grid Filter

Figueres Amorós, Emilio; Garcerá, Gabriel; Sandía Paredes, Jesús; González Espín, Francisco José; Calvo Rubio, Jesús (Institute of Electrical and Electronics Engineers, 2009)

[EN] An accurate small-signal model of three-phase photovoltaic (PV) inverters with a high-order grid filter is derived in this paper. The proposed model takes into account the influence of both the inverter operating point ...
Técnicas de filtrado adaptativo aplicadas al rechazo selectivo de perturbaciones en inversores fotovoltaicos trifásicos

González Espín, Francisco José (Universitat Politècnica de València, 2011-02-25)

La conexión de paneles solares fotovoltaicos a la red eléctrica puede llevarse a cabo mediante el empleo de inversores de potencia tipo VSI (Voltage Source Inverter). Los inversores pueden ser controlados en un marco de ...
Transformerless topologies for grid-connected single-phase photovoltaic inverters

Patrao Herrero, Iván; Figueres Amorós, Emilio; González Espín, Francisco José; Garcerá Sanfeliú, Gabriel (Elsevier, 2011-09)

[EN] In order to improve the efficiency and reduce the cost of a photovoltaic system, the use of transformerless photovoltaic inverters is an alternative of increasing interest. However, this topology needs to be studied ...
