Caracterización de la tolerancia a fallos de circuitos implementados en FPGAs
(2019-05-17)
Las FPGAs (Field-Programmable Gate Array) y los SoC (System-on-chip) basados en FPGA son dispositivos electrónicos configurables en campo (in field), que ofrecen la posibilidad de desarrollar un circuito a medida con un ...
Arquitecturas system-on-chip para cyber physical system gateway en smart grid
(2019-06-28)
La forma en que funciona la red eléctrica no ha cambiado mucho desde su creación en la década de 1930, los métodos y medios de transmisión de los datos siguen siendo similares. Aunque la infraestructura general permanece ...
Mitigation of Common Mode Voltage Issues in Electric Vehicle Drive Systems by Means of an Alternative AC-Decoupling Power Converter Topology
(MDPI, 2019-08-30)
Electric vehicles (EV) are gaining popularity due to current environmental concerns. The electric drive, which is constituted by a power converter and an electric machine, is one of the main elements of the EV. Such machines ...
Photovoltaic Energy Harvesting System Adapted for Different Environmental Operation Conditions: Analysis, Modeling, Simulation and Selection of Devices
(MDPI, 2019-04-01)
The present research work proposes a photovoltaic energy harvester and an appropriate direct current (DC)/DC converter for a harvesting system after the study of the devices and taking the operation conditions. Parameters ...
New monitoring method to characterize individual modules in large photovoltaic systems
(Pergamon-Elsevier, 2019-11-15)
Photovoltaic (PV) systems power losses are approximately 15-20% of the performance ratio for current PV systems. There are several reasons that explain PV modules failures, and since they are connected in series to the ...

Hoy en día, el VE es la opción mejor posicionada para sustituir masivamente a los automóviles tradicionales en el mercado a medio y largo plazo. Sin embargo, y a pesar de las previsiones tan optimistas, son aún muchos los ...
A new voltage probe with improved performance at the 10 kHz–500 kHz frequency range for field measurements in LV networks
(Elsevier, 2019-06-05)
[EN] Voltage measurements in the frequency range from 10 kHz to 500 kHz are used to quantify the level of the Narrow Band Power Line Communication transmitted signals, the noise and the non-intentional conducted emissions ...
ECG-based pulse detection during cardiac arrest using random forest classifier
(Springer, 2019)
Sudden cardiac arrest is one of the leading causes of death in the industrialized world. Pulse detection is essential for the recognition of the arrest and the recognition of return of spontaneous circulation during therapy, ...
Energy Harvesting Technologies and Equivalent Electronic Structural Models - Review
(MDPI, 2019-04-25)
As worldwide awareness about global climate change spreads, green electronics are becoming increasingly popular as an alternative to diminish pollution. Thus, nowadays energy efficiency is a paramount characteristic in ...
RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band
(Wiley, 2019-11-19)
Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were ...
