(Universitat Politècnica de València, 2023)
Work for inclusive, quality education and the reduction of inequalities is
among the prioritised lines of action promoted by the Sustainable Development
Goals of the United Nations (2015). In the context of higher ...
Ephemeral rivers, geomorfphological evolution and mapping. A case study in NE Iberian Peninsula
(International Association of Geomorphology, 2022-09)
Ephemeral rivers (IRES – Intermittent Rivers and Ephemeral Streams) differ from perennial rivers in that they do not have a base flow, therefore, when direct flow stop, they dry up. This condition is spatially accentuated ...
Geomorphological evolution of ephemeral rivers through historical and UAVs images
(EGU, 2022-04-19)
Ephemeral rivers hydromorphological processes are intermittent and many times of fast response. Therefore they remain still quite unknown. The geomorphological mapping of river forms and geomorphological units is a useful ...
Sediment displacement evolution after dam removal in a mountain river (Oioki dam, Leitzaran River)
(EGU, 2021-04)
Bedload sediment transport was monitored from 2016 to 2020 in the Leitzaran River, in a reach affected by the removal of 7-meters high dam (Oioki dam). The removal was accomplished in two phases, the 3 first meters were ...
Influencia de las modulaciones PWM en las pérdidas de potencia de los condensadores del DC-Link en inversores VSI multifásicos
(2022)
En aplicaciones de tracción eléctrica, los accionamientos multifásicos se están convirtiendo en una alternativa a tener en cuenta frente a sus homólogos trifásicos, debido a una serie de ventajas que compensan su coste ...
Normalised hybrid flux weakening strategy for automotive asymmetrical dual three-phase IPMSMs
(IEEE, 2022-12-09)
In this paper, a hybrid flux weakening control strategy based on a vector space decomposition (VSD) model is presented for asymmetrical dual three-phase interior permanent magnet synchronous machines (IPMSMs). This strategy ...
Reducción de la corriente por el condensador del DC-link mediante modulación e interleaving para máquinas asimétricas duales trifásicas
(2023)
El condensador del bus de continua (bus d.c.) desempeña un papel fundamental en lo que respecta a la densidad de potencia y la fiabilidad del inversor. Los accionamientos de máquinas asimétricas duales trifásicas (asymmetrical ...
Influence of PWM modulations on the DC-Link capacitor power losses of multiphase VSIs
(IEEE, 2022-12-09)
In traction applications, particularly in transport electrification, multiphase drives are increasingly being an interesting alternative over their three-phase counterparts due to a range of advantages outweighing the ...

Loss and stress reduction in VSI devices for EVs using general discontinuous PWM
(2016-07-06)
In this paper, a new carrier based discontinuous pulse width modulation (DPWM) strategy for voltage source inverter (VSI) is presented in order to use in electric vehicles (EV). The basic idea of DPWM techniques, is clampimg ...
