Frequency Dependent Model of Leakage Inductance for Magnetic Components
Advanced Electromagnetics, 2012 Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
Advanced Engineering Materials, EarlyView.This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Matrix Transformer with Integrated Leakage Inductance
2025 7th Global Power, Energy and Communication Conference (GPECOM)Due to the rapid growth of electric aircraft, the need for high-power converters with significant weight reduction has increased. This article proposes a matrix transformer as a solution for isolated DC/DC converters (270V/28V). The matrix transformer enable the integration of leakage inductance through a five-leg magnetic core geometry.

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects
Advanced Engineering Materials, EarlyView.Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
