Control of a photovoltaic array interfacing current-mode-controlled boost converter based on virtual impedance emulation
(IEEE, 2019)
info:eu-repo/semantics/article,
Due to the nonlinear characteristics of a photovoltaic (PV) array, its regulation is highly dependent on the operating point. Focusing on a dc-dc boost converter, this paper first shows how the PV voltage and inductor ...
Modeling ground-shielded integrated inductors incorporating frequency-dependent effects and considering multiple resonances
(IEEE, 2019)
Artículo / Artikulua,
A model for integrated spiral inductors which incorporates the physically expected frequency-dependent effects modifying the device's impedance is proposed. Moreover, it is demonstrated that the effect of resonances occurring ...
The potential of forecasting in reducing the LCOE in PV plants under ramp-rate restrictions
(Elsevier, 2019)
Artículo / Artikulua,
An increasing number of grid codes are requiring the limitation of the PV output power fluctuation over a
given time scale. Batteries represent the most obvious solution to smooth power fluctuations, with the
corresponding ...
Modelización de parques eólicos conectados a redes débiles
(2019)
info:eu-repo/semantics/doctoralThesis,
El aumento de penetración eólica producido a escala mundial está propiciando la conexión
de una gran cantidad de parques eólicos a redes débiles. Esto supone un reto para los
operadores de la red y de los propios parques ...
Estrategias de control para inversores fotovoltaicos de gran potencia en redes muy débiles
(2019)
info:eu-repo/semantics/doctoralThesis,
La energía fotovoltaica ha experimentado un gran crecimiento en el mundo en los ultimos años, motivado principalmente por el descenso de su
precio durante la ultima década. Esta reducción de costes ha hecho que se
convierta ...
Determinación de los umbrales ventilatorios, metabólicos y electromiográficos durante el test de esfuerzo incremental en ciclistas de elite
(2019)
info:eu-repo/semantics/doctoralThesis,
La fatiga muscular tiene múltiples definiciones, pero indudablemente su principal misión es la protección. La electromiografía de superficie (sEMG) es una técnica adecuada para comprender los patrones de activación musculares, ...
Photonic nanojets with mesoscale high-index dielectric particles
(AIP Publishing, 2019)
Artículo / Artikulua,
In this work, we demonstrate the ability of high-index dielectric particles immersed in air to generate photonic nanojets with extreme resolution (∼0.06λ0). Both 2D (cylindrical) and 3D (spherical) particles are analyzed, ...
±0.25 V Class-AB CMOS capacitance multiplier and precision rectifiers
(IEEE, 2019)
Artículo / Artikulua,
Reduction of minimum supply requirements is a crucial aspect to decrease the power consumption in VLSI systems. A high performance capacitance multiplier able to operate with supplies as low as ±0.25 V is presented. It is ...
Contributions to the development of Brillouin distributed sensors for structural health monitoring
(2019)
info:eu-repo/semantics/doctoralThesis,
The main objectives of this thesis is to contribute to the enhancement of the performance of distributed optical ber sensors (DOFS) based on stimulated Brillouin scattering (SBS) by analyzing their limitations and proposing ...
Development of sub-millimetre wave band subsystems and packaging techniques
(2019)
info:eu-repo/semantics/doctoralThesis,
En esta tesis se investigan técnicas de diseño y fabricación de dispositivos, ya sean transmisores o receptores, a frecuencias de THz y submilimétricas y técnicas de empaquetado con el objetivo de que el dispositivo final ...
