The Laboratory of Industrial Electronics and Instrumentation (LEII) is a research group whose main objective is the study and application of power electronics and instrumentation to different fields of technology. This translates into the existence of several lines of research within the LEII.

These lines are: high power resonant converters, power electronics devices, aerospace power converters, three-phase power converters and finally electronic instrumentation. In the line of high-power resonant converters, generally resonant, high-power converters (from 3 kW up to 1 MW designs) are developed. These converters are applied to industrial processes such as induction. Research is currently focused on new battery chargers for electric vehicles. The power electronics devices line specialises in the development of tests for the electro-thermal characterisation, both static and dynamic and in switching, of semiconductor devices, especially new families such as SiC and GaN. The aerospace power converters line focuses its work on the development of DC/DC converters for aerospace applications and therefore taking into account the peculiarities of this highly specialised niche market. To highlight LEII's experience having developed the power supply for the PHI experiment that will fly on board the Solar Orbiter satellite, scheduled for launch in 2017. The line of three-phase power converters focuses on grid connection inverters for renewable energy applications, controlled rectifiers for wind power generation, active power filters, reactive power compensators and drivers for electrical machines. It is worth highlighting the experience in programming advanced micro-controllers for the implementation of the control algorithms of these converters. Finally, the electronic instrumentation research line has expertise, among other areas, in new spintronic magnetoresistive devices and their application as electronic sensors. It also has extensive experience in the development of systems for the electronic measurement and conditioning of electrical and physical parameters and the subsequent analysis and acquisition of these measurements using computers and microcontrollers.
