Simple and Affordable Method for Fast Transient Measurements of SiC Devices
(IEEE, 2020)
The measurement of fast voltage and current transients of Silicon Carbide (SiC) devices requires high bandwidth (BW) probes. Commercially available voltage and current probes can be expensive, and, in addition, the delay ...
Integral Design and Manufacturing Methodology of a Reduced-Scale Servo Press
(IEEE, 2021)
In a context where industrial production boosts both the society and the economy of a country, improvements in industrial processes are key factors for efficient and reliable development of goods and products. New industrial ...
A Methodology to Determine the Effect of a Novel Modulation in the Reliability of an Automotive DC-Link Capacitor
(IEEE, 2020)
Switched Reluctance Machines (SRM) are considered promising rare-earth free candidates for the next generation electrified vehicles. One of the main drawback of this technology is the need of a large DC-link capacitor to ...
Study of Astroloy powder compaction at high temperature under hydrostatic load using finite elements
(Elsevier, 2021)
The results of existing constitutive models describing the behaviour of metal powder during compaction processes are very different. This reveals the high sensitivity of the mechanical behaviour of porous materials to the ...
Synchronized Switching Modulation to Reduce the DC-Link Current in SRM Drives
(IEEE, 2020)
Switched Reluctance Machines (SRM) are emerging as a possible alternative in terms of cost and supply stability to rare earth based electric vehicle traction systems. However, because of the huge amounts of energy stored ...
Study of powder densification under hydrostatic loads at high temperatures using finite element method
(Elsevier, 2020)
Many different constitutive models that describe the behaviour of metal powder during hot isostatic processes are found in literature. A quantitative comparison of these material laws shows a huge discrepancy among the ...
A method to extract lumped thermal networks of capacitors for reliability oriented design
(Elsevier, 2020)
In this work we propose a procedure based on finite element simulations to compute a lumped-parameter thermal model of capacitors. The extracted Foster or Cauer network coupled to the electrical model can be useful to ...
Thermal Mass Effect on the Solution Cooling Rate and on HIPped Astroloy Component Properties
(MDPI, 2022)
Astroloy is a Ni-based superalloy with high-volume fraction of γ′, which gives high temperature properties but reduces its forgeability. Therefore, powder metallurgy manufacturing processes such as Near Net Shape HIPping ...
