On the testing, characterization, and evaluation of PV inverters and dynamic MPPT performance under real varying operating conditions
(Wiley, 2007)
Artículo / Artikulua,
The increasing number of photovoltaic inverters that are coming on to the PV marketstresses the need to carry out a dynamic characterization of these elements and theirmaximum power point tracking (MPPT) algorithms under ...
Design methodology for the frequency shift method of islanding prevention and analysis of its detection capability
(Wiley, 2005)
Artículo / Artikulua,
Islanding protection is one of the most important sources of discrepancy in gridconnected photovoltaic systems. Even when islanding is not very likely to happen,
regulations demand the photovoltaic inverters to implement ...
Boost DC-AC inverter: a new control strategy
(IEEE, 2005)
Artículo / Artikulua,
Boost dc–ac inverter naturally generates in a single
stage an ac voltage whose peak value can be lower or greater than
the dc input voltage. The main drawback of this structure deals
with its control. Boost inverter ...
Electronic controlled device for the analysis and design of photovoltaic systems
(IEEE, 2005)
Artículo / Artikulua,
The characterization and design of photovoltaic systems is a difficult issue due to the variable operation atmospheric conditions. With this aim, simulators and measurement equipments have been proposed. However, most of ...
Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
Development of an in-fiber nanocavity towards detection of volatile organic gases
(MDPI, 2006)
Artículo / Artikulua,
A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has been developed and characterized for some organic gasses. The sensor is based on a novel vapochromic material, which is able to change its optical ...
Pyridine vapors detection by an optical fibre sensor
(MDPI, 2008)
Artículo / Artikulua,
An optical fibre sensor has been implemented towards pyridine vapors detection; to achieve this, a novel vapochromic material has been used, which, in solid state, suffers a change in colour from blue to pink-white in ...
Diseño de filtros banda rechazada usando Defected Ground Structures (DGS)
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a type of Defected Ground Structure (DGS) is studied and used to implement filters in microstrip technology. It is first demonstrated that the main parameter which controls its operation is the external ...
Choked-gaussian corrugated horn antenna design small global coverage horn antenna for TT&C with extremely low sidelobe level
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
Extremely low sidelobe horn antennas are often required for the actual technology. This type of horn antennas are
important to avoid interference with other systems.
In this paper we describe a new design implementing a ...
Simple modelling of DGS to design 1D-PBG low-pass filters
(Wiley, 2003)
Artículo / Artikulua,
The use of defected ground structures (DGS) is being intensively explored by the microwave filter designer community. The DGSs are one possible implementation of a 1D Photonic Band Gap (1D-PBG) where some defect structures ...
