Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation
Advanced Science, Volume 13, Issue 18, 27 March 2026.Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper adopts a Neutral‐Point‐Clamped H‐bridge (NPC‐H) DAB topology to mitigate voltage stress on the input‐side switches. For both charging and discharging scenarios, a direct current control method is proposed using the output current as the primary control variable.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This study explores fault diagnosis methods for PWM inverters in a wind energy conversion system using a doubly fed induction generator. Two intelligent diagnostic techniques, fuzzy resonant logic and artificial neural networks, are proposed. The fuzzy logic method monitors inverter faults in real time, whereas the neural network method uses 3D feature

A Highly Efficient Single-Phase Three-Level Neutral Point Clamped (NPC) Converter Based on Predictive Control with Reduced Number of Commutations [PDF]
Energies, 2018 This paper proposes a highly efficient single-phase three-level neutral point clamped (NPC) converter operated by a model predictive control (MPC) method with reduced commutations of switches. The proposed method only allows switching states with none or a single commutation at the next step as candidates for future switching states for the MPC method.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.ABSTRACT High‐phase electronic pole‐changing induction machines (ePCIMs) offer inherent redundancy and extended torque‐speed capability, making them suitable for high‐power traction applications such as electric buses and heavy‐duty electric vehicles. However, pole‐changing transitions produce severe transient currents that degrade dynamic performance ...
