Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors

Energy Science &Engineering, EarlyView.
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.

Patient Experience of Undergoing MRI With a New Active Transcutaneous Bone‐Anchored Hearing Implant

The Laryngoscope, EarlyView.
Active transcutaneous bone‐anchored hearing implants belong to a class of devices that may pose challenges in magnetic resonance imaging (MRI) settings. In this prospective study, all MRI scans in patients (n = 15) with the Sentio Ti implant were completed without complications, and patients reported generally positive experiences with low levels of ...

Giant Exfoliation Induced Magnetic Coercivity in Fe3GaTe2

Advanced Electronic Materials, Volume 12, Issue 15, 10 August 2026.
Mechanical exfoliation is shown to transform the van der Waals ferromagnet Fe3GaTe2 from a soft into a hard magnetic system. Reducing thickness drives a crossover to single‐domain behavior, dramatically enhancing in‐plane coercivity to near–permanent‐magnet levels at room temperature.

Enhanced Performance of Three‐Phase Induction Motor Based Inter‐Turn Faults Using Finite Element

Engineering Reports, Volume 8, Issue 8, August 2026.
In this work, the efficiency of the three‐phase squirrel cage induction motor in terms of inter‐turn faults has been enhanced by using finite element analysis and ANSYS Maxwell program. However, some parameters, such as flux distribution, flux density, output power, phase currents, and electromagnetic torque, have been taken into account to perform the
