Partial Power Converters for DC-DC Applications
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
This thesis studies partial power processing (PPP) based architectures for DC-DC applications. This type of solutions aim to reduce the power processed by the power converter. This way, the power losses and the volume of ...
Control of interlinking converters for hybrid AC/DC power systems
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
Electrical power plays a very important role in today’s society, but the necessity to reduce the greenhouse gas emissions requires to shift the classical fossil fuel-based power generation towards a renewable based model. ...
Identificación de los aspectos clave de la economía circular para su inclusión en el diseño para el ciclo de vidaIdentification of key aspects of circular economy for inclusion in life cycle design
(AEIPRO, 2019)
La sostenibilidad de la sociedad va a requerir cambios en las personas, en las organizaciones y en las administraciones públicas. La economía circular se postula como un elemento tractor de ese cambio. Pero, ¿cómo abordar ...
Modular Battery Systems’ Accessible Energy Analysis
(2022)
One of the main concerns regarding traditional battery energy storage systems (BESS) is how to solve issues related to cell inhomogeneities. This problem commonly ends up reducing the accessible energy level, especially ...
Multiphysics modeling and experimental validation of heat and mass transfer for the vacuum induction melting process
(Elsevier, 2024)
Vacuum induction melting is crucial in casting nickel-based superalloy components, ensuring excellent properties for aero-engine applications. Precise melting temperatures are vital for achieving optimal metallurgical ...
Effect of liner thermal properties and liner pre-cooling on the thermal management of fast-filling of hydrogen tanks
(Elsevier, 2023)
In transportation applications, filling high pressurised hydrogen tanks within a few minutes implies a fast and large temperature increase that can compromise the structural integrity of the storage system and the safety ...
PEM motako erregai-pilen zenbakizko analisia eta balioztatze esperimentala
(Udako Euskal Unibertsitatea (UEU), 2023)
Gaur egungo aldaketa klimatikoa dela medio, energia elektrikoa lortzeko alternatiba berri ugari sortzen ari dira. Horien artean erregai-pilek abantaila suposatzen dute hainbat esparrutan. Ikerketa honetan gaur egun garapen ...
Design and characterization of a novel lightweight multicomponent alloy Al58Zn28Mg6Si8
(Elsevier, 2023)
This paper presents a novel multicomponent alloy Al58Zn28Mg6Si8, with a density of 3.46 g/cm3, which incorporates concepts from high entropy alloys. The optimum alloy composition was determined using the CALPHAD approach ...
Magnet eddy current loss calculation method for segmentation analysis on permanent magnet machines
(IEEE, 2011)
Eddy current losses generated in the rotor of permanent magnet machines may lead to an excessive magnet heating. This can cause the magnets to get fully demagnetized so it is very important to analyze the losses on them. ...
Impact and notched strength of multiaxially reinforced out of die UV cured pultruded profiles
(Wiley, 2024)
The present paper highlights the benefits of multiaxially reinforced profiles manufactured by out of die ultraviolet (UV) cured pultrusion. Thanks to the low pulling forces inherent to this technology, we could manufacture ...
