Roll levelling semi-analytical model for process optimization
(IOP, 2016)
Roll levelling is a primary manufacturing process used to remove residual stresses and imperfections of metal strips in order to make them suitable for subsequent forming operations. In the last years the importance of ...
Analytical Model of the Current Stress in Active-Bridge Active-Clamp Converter for More Electric Aircraft
(IEEE, 2021)
Nowadays, the emergence of electrically supplied actuators and energy storage systems is leading the aeronautic industry to develop aircrafts with more electrical power installed. Therefore, different Power-Electronic ...
Radial fan simulations by computational fluid dynamics and experimental validation
(IEEE, 2014)
Fans are commonly used to refrigerate electrical machines when air forced cooling is required. They are rather simple solutions that can considerably improve the thermal performance of electrical machines, so the fan ...
Towards the Isolation of Failure-Inducing Inputs in Cyber-Physical Systems: is Delta Debugging Enough?
(IEEE, 2022)
Cyber-Physical Systems (CPSs) combine digital cyber technologies with parallel physical processes. On the one hand, verification methods of such systems mostly rely on (system level) simulation-based testing. This technique ...
High-Frequency Modelling of Windings
(IEEE, 2022)
Electrical drives consume a great amount of the world’s energy, and this will keep increasing due to the electromobility trend. Hence, the efficiency of electrical drives must be improved to reach sustainability. Silicon ...
Analysis of Interleaved Input-Parallel Output-Parallel Dual-Active-Bridge Converter for More Electric Aircraft
(IEEE, 2021)
Dual-Active-Bridge (DAB) converter is one of the most proposed topologies when considering DC/DC bidirectional isolated power conversion. In these applications, the power density of the converter is one of the main ...
Thermal test procedure and analytical model calibration method for electrical machines
(IEEE, 2013)
In this paper a thermal test procedure and a calibration method for lumped parameter models are presented. Analytical models provide fast thermal simulations in comparison with finite element methods (FEM) and computed ...
Dynamic Wireless Power Transfer DWPT Time Domain model: xyz position and speed coupling effect
(IEEE, 2022)
The paper presents a DWPT system time domain model which considers speed and position (x, y, z) coupling effects. The speed effect compared to static WPT, presents an active behavior that should be considered during the ...
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 ...
Model driven Hardware-in-the-Loop Fault analysis of railway traction systems
(IEEE, 2017)
Classical Dependability Analysis techniques, such as Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis, have been used during the last decades to demonstrate the reliability, availability, maintainability ...
