Loss Measurement of Low RDS Devices Through Thermal Modelling - The Advantage of Not Turning it Fully On
(IEEE, 2023)
This paper presents and evaluates a novel method for generating power losses on transistors avoiding high currents. These could heat up the circuit tracks, affecting the accurate thermal modeling of the system. The proposed ...
Design and analysis of a voltage ride-through testing solution based on a novel medium-voltage OLTC auto-transformer
(IEEE, 2023)
In this paper, a novel medium-voltage auto-transformer capable of generating under- and over-voltage conditions is introduced. The auto-transformer could emulate grid disturbances at 20kV, 30kV and 35kV, satisfying the ...

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 ...
Baterien segurtasun-egoera iragartzea (SoS)
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
Gaur egun, teknologiak aurrera egin ahala, bateriak funtsezko osagaiak bihurtu dira, gehien bat, erabilienak, litio ioizko bateriak (LIB). Hala ere, hauen segurtasunarekiko kezka oraindik ere kritikoa da. Hori dela eta, ...
Li-ioi baterien degradazio-ereduen garapena, transferentzia bidezko ikaskuntza-metodoen bidez
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2020)
Li-ioi bateriak garestiak dira eta degradatu egiten dira; hori dela eta, degradazio-eredu bat sortu beharra dago, bateriek xede-aplikazioan zer portaera izango duten eta zenbat iraungo duten simulatzeko. Ereduok sortzeko, ...
Indukzio bidezko berokuntza sistema bat diseinatzea, abiaraztea eta balioztatzea
