Research Activities


My main research activities are currently on the LEMUR research team, at the University of Oviedo.

Also, I keep collaborating with the CE3I2 research team, also from the University of Oviedo.

During my research trajectory, I have collaborated with the following research groups of other universities:
 GEDRE research group, from UFSM, Brazil.
 Laboratory of Electric Machines, from Universitá di Roma - La Sapienza, Italy.

I've carried out research in Power Electronic applied to lighting systems from 1999. From 2009, the research fields include specifically more wide research lines of Power Electronics Engineering, such as: 

 Power Electronic Converters, including power topologies, control schemes and modeling, digital control, integration of stages, magnetic components. 

 Modeling and characterization of lamps, electric and physic behavior of lighting sources, discharge lamps, LED lamps. 

 Power converters for lighting, lighting electronics, complex multi-point lighting systems 

 Industrial applications, sensor networks, electronic communication systems, ozone generation for industrial or residential applications.
