A High Frequency Magnetic Test Bench with Fast Isothermal Measurements for Large Cores
(IEEE, 2023)
This paper presents a magnetic core test-bench that has been developed for high-frequency measurements. The bench is able to perform tests at 1 MHz, 300 V and in a range of 20 °C to 150 °C. It exhibits precise temperature ...
Comparison between the ETT and LTT Technologies for Electronic OLTC Transformer Applications
(IEEE, 2023)
This paper introduces a novel electronic tap-changer application for renewables with light-triggered thyristors for medium-voltage transformers. The on-chip functionality and robustness of the thyristor support applications ...
Análisis del efecto de shot-peening y el cementado en la vida a fatiga de los engranajes
(Sociedad Española de Integridad Estructural - Grupo Español de Fractura SEIE-GEF, 2023)
Debido a sus condiciones de trabajo, la fatiga es uno de los modos de fallo más comunes en los engranajes. A pesar de que habitualmente se emplean diversos tratamientos para mejorar las propiedades mecánicas de los mismos, ...
Analytical, FEM and Experimental Study of the Influence of the Airgap Size in Different Types of Ferrite Cores
(IEEE, 2022)
This work reviews and compares different airgap reluctance calculation approaches with experimental results, focusing on the Schwarz-Christoffel transformation. The modelling of the airgap reluctance in two dimensions is ...
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 ...
Damping characterisation of an elevator rope
(ISMA, 2022)
The ropes of an elevator transmit the vibrations from the motor to the elevator car, and consequently have a great influence on comfort. Therefore, it is of major interest to analyse the dynamic behaviour of these elements. ...
Noise attenuation prediction and analysis in rectangular lined ducts
(ISMA, 2022)
The noise of Heating, Ventilating and Air Conditioning (HVAC) systems is an important aspect when the comfort of the users is compromised. Thus, solutions to attenuate that noise need to be proposed. Linings in ducts are ...
Mondragon ZTIM-HUB: the collaborative network for the development of stem vocations
(2022)
It is well known that STEM (Science, Technology, Engineering & Mathematics) is one of the most heard concepts both in the field of education and in the business sphere, when talking about the socio-economic needs of the ...
Application of Computer Vision and Deep Learning in the railway domain for autonomous train stop operation
(IEEE, 2020)
The purpose of this paper is to present the results of the analysis of the application of Deep Learning in the railway domain with a particular focus on a train stop operation. The paper proposes an approach consisting of ...
