Evolutionary generation of metamorphic relations for cyber-physical systems
(ACM, 2022)
A problem when testing Cyber-Physical Systems (CPS) is the difficulty of determining whether a particular system output or behaviour is correct or not. Metamorphic testing alleviates such a problem by reasoning on the ...
An Interoperable EMS for the Provision of Grid Services with Hybrid Energy Storage Systems
(IEEE, 2022)
This paper proposes an interoperable energy management system (EMS) for grid-connected HESSs, enabling the provision of ancillary services to the grid. Power systems are evolving towards a more renewable and decentralised ...
Single Core and Modular Transformer Solutions: a Trade-Off Analysis of Volume, Losses and Temperature Rise
(IEEE, 2022)
In this paper, a comparison between single core and modular transformer solutions is made. Basic dimensional relations between volumes, areas and lengths are used to obtain mathematical expression of the power losses and ...
Novel Analytical Method for Estimating the Junction-to-Top Thermal Resistance of Power MOSFETs
(IEEE, 2022)
This papers proposes a new methodology for estimating the thermal resistance from the junction-to-top capsule surface. By placing the transistor in a vertical position, without being soldered to any PCB, and sensing the ...

Dynamic Wireless Power Transfer DWPT Time Domain model: xyz position and speed coupling effect
(IEEE, 2022)
The paper presents a DWPT system time domain model which considers speed and position (x, y, z) coupling effects. The speed effect compared to static WPT, presents an active behavior that should be considered during the ...
Benefits of switching from Si to SiC modules with further converter optimization
(IEEE, 2022)
SiC semiconductors have better characteristics than Si, improving power electronics converters performances. A prototype that can switch semiconductor technology without changing any other part of the system is built and ...
Implantación colectiva de la clase invertida en el grado de informática
(AENUI, 2022)
La educación ha sufrido una gran transformación en las últimas décadas. El alumnado de hoy en día está formado por nativos digitales y la educación tradicional les parece aburrida. Por este motivo, los docentes tratan de ...
