This work is a contribution to a measuring system based on ultrasonic techniques to analyse and monitor, in real time, malolactic fermentation (MLF) in red wine, both at industrial and semi-industrial ...
Camacho Santiago, Antonio (Fecha de defensa: 2015-07-17)
The objective of this thesis is the development of control strategies for distributed generation systems during voltage sags. The proposed control strategies present different options to improve the ...
Guzmán Solà, Ramon (Fecha de defensa: 2016-10-14)
The present thesis is focused on the control of three-phase power converters using sliding-mode control (SMC) in abc frame. This work has been based on previous publications about the SMC applied to ...
Barrenechea Gruber, Roberto Carlos (Fecha de defensa: 2019-01-11)
In this work, a new algorithm for the multiobjective optimization of low and medium voltage electrical grids and microgrids is proposed. The originally nonlinear planning model is linearized using the ...
Lamich Arocas, Manuel (Fecha de defensa: 2015-02-27)
The increasing use of DC electronic devices connected to mains lead to numerous complications of harmonic distortion and efficiency reduction in electrical energy transmission. These devices behave as ...

El procesamiento de la energía mediante convertidores electrónicos conmutados ha tomado una relevancia notable durante la última década, y presumiblemente será uno de los campos de la ingeniería con ...
Borrell Sanz, Angel (Fecha de defensa: 2012-07-12)
The multiphase synchronous buck converter is universally used today for powering low voltage, high current and high slew-rate loads, such as CPUs and other high performance digital ICs. This converter ...
Sarriá Gandul, David (Fecha de defensa: 2014-04-02)
In this Thesis, new methods for monitoring marine species using optical, radio frequency and acoustic technologies have been proposed and evaluated for biological studies in the laboratory and open ...
Moure García, David (Fecha de defensa: 2017-06-29)
The global seismic activity is extensively studied and well characterized by seismic networks focused on the seismic hazards derived from earthquakes. However, a specific study on volcano seismicity is ...
