Magnetic Behavior of NO Fe-Si Sheets under Tensile and Compressive Stress

The stress dependence of the magnetic properties of non-oriented Fe-Si steel sheets has been investigated by measurement and analysis of hysteresis loop, magnetization curve, and energy losses taken at different peak polarization values J p (0.5 T …

Topology Optimization of a Complete Reluctance Machine with no Initial Information on its Geometry

This paper addresses the topology optimization of an entire multiphase reluctance machine. Multiple materials are automatically and simultaneously distributed in the rotor and stator to maximize torque, minimizing the designer bias. As an extension…

Training Data Generation Strategies for Data-driven Security Assessment of Low Voltage Smart Grids

Control of small-scale resources in low and medium voltage electricity networks is being decentralised, which increases the need and frequency of use of smart grid security assessment tools. This paper compares three data-driven approaches to…

UV-A-Irradiated P(VDF-TrFE-CFE) as a High-Efficiency Refrigerant for Solid-State Cooling

Thin P(VDF-TrFE-CFE) films have become an essential active material in the manufacturing of solid-state refrigeration systems. Films prepared by solvent casting fall short of the performance needs of today’s cooling devices due to their low…

Enhancement of the Piezocatalytic Response of La‐Doped BiFeO$_3$ Nanoparticles by Defects Synergy

Because of their intrinsic polarization and related properties, ferroelectrics attract significant attention to address energy transformation and environmental protection. Here, by using trivalent‐ion‐lanthanum doping of BiFeO$_3$ nanoparticles (NPs…

Kalman filter for radio source power and direction of arrival estimation

Images are an important source of information for spacecraft navigation. Based on an image and a known attitude, triangulation techniques (intersection or resection) are often used for positioning and navigation. In the resection problem, an…

A new closed-loop regulation method dedicated to piezoelectric resonators based isolated DC-DC converter

Magnetic components are widely used in power electronics. Yet, their downscaling with frequency becomes moderate from 100 kHz, which limits the possibility of reducing the volume of the passive components in power converters. Therefore, a major…

Gate-Driving Performance Evaluation Based on a New Figure of Merit

Fast switching within static converters is a key to high-efficiency operation and a source of electromagnetic disturbances that can harm the proper functioning of the converters themselves or the electronic equipment placed in their neighborhood. To…
