Hydromorphological characterization, assessment and monitoring in ephemeral streams: a case study in NE Iberian Peninsula
(International Association of Geomorphology, 2022-06-20)
Ephemeral streams are an important reality in the Mediterranean area, constituting more than 50% of the channel network in the eastern region of the Iberian Peninsula. The northernmost cases are located in the semi-arid ...
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 ...
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 ...
Tecnología de los condensadores del tren de tracción del EV: condensadores del bus DC
(SAAEI, 2021-07-07)
Los organismos e instituciones internacionales consideran la electrificación del sector del transporte un factor clave para hacer frente a los retos ambientales y energéticos de los próximos años. Para que los vehículos ...
Determinación de las referencias de corriente en máquinas síncronas mediante cálculos analíticos normalizados y realimentación
(SAAEI, 2022)
En este artíıculo se presenta una estrategia de control mixta para determinar las trayectorias de corriente óptimas de una máquina síncrona de imanes permanentes (PMSM) en las regiones de máximo par por amperio (MTPA), ...
Series capacitor tapped buck para aplicaciones en imanes superconductores
(SAAEI, 2022-07-06)
Durante la última década las aplicaciones que requieren una gran reducción de tensión, se han convertido en un tema emergente en la electrónica de potencia. Entre algunos ejemplos están el suministro de energía a los ...
