A New Bidirectional Three-phase Neutral Point Clamped (NPC) Grid-Connected Converter: Analysis and Simulation

Anais do Simpósio Brasileiro de Sistemas Elétricos 2020, 2020
This paper deals with the theoretical development, analysis, and simulation of the new topology of three-phase NPC (Neural Point Clamped) converter. The proposed 6-kW three-phase converter is connected to a three-phase electrical network and due to its bidirectional characteristics can either send energy to the grid or receive it from the grid.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Targeting the PDK1/c‐Myc/SOX10 Signaling in Oligodendrocytes Alleviates Neuropathic Pain

Advanced Science, Volume 13, Issue 39, 13 July 2026.
This work reveals that oligodendrocyte homeostasis, mediated by PDK1, is a critical determinant of neuropathic pain (NPP) pathogenesis. Disruption of PDK1 in oligodendrocytes impairs SOX10‐dependent myelination programs through c‐Myc accumulation, leading to disrupted myelination and the pathophysiology of NPP.

Design Analysis of a Seven‐Level Active Neutral Point Clamped (ANPC) Inverter Based on Switched Technique

Radio Science, Volume 61, Issue 4, April 2026.
Abstract A novel switch‐based Active‐Neutral‐Clamped (ANPC) inverter for low DC‐link voltage is presented in this paper. The proposed ANPC topology minimizes switches and achieves 1.5 times better voltage gain than standard inverters. The main objective of this design is to reduce active switches in the inverter to increase system efficiency.

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

A Five‐Level Active Neutral‐Point‐Clamped Auxiliary Inverter Based on Reverse Blocking IGBT in Metro Applications

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.

Natural Soft‐Switching Extended Phase‐Shift Control of Dual Active Bridge for High‐Efficiency Battery Charging and Discharging

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.

Fault Diagnosis Methods Based on Fuzzy Logic and Artificial Neural Networks Approaches for Wind Turbine PWM Inverter

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
