Comparative Studies of Different Control Strategies of a Dynamic Voltage Restorer Based on Matrix Converter [PDF]
, 2012 A dynamic voltage restorer (DVR) with no energy storage is studied. By using a matrix converter instead of the conventional AC/DC/AC converters, elimination of the DC-link capacitor is possible.

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials
Advanced Materials, EarlyView.Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

Fuzzy Controlled Parallel AC-DC Converter for PFC
Advances in Electrical and Electronic Engineering, 2011 Paralleling of converter modules is a well-known technique that is often used in medium-power applications to achieve the desired output power by using smaller size of high frequency transformers and inductors. In this paper, a parallel-connected single-phase PFC topology using flyback and forward converters is proposed to improve the output voltage ...

High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production
Advanced Materials, EarlyView.This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Advanced Materials, EarlyView.We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

FUZZY BASED CONTROLLER FOR AC/DC BOOST CONVERTER
Iraqi Journal for Electrical and Electronic Engineering, 2006 In this papcr, a fuzzy based controller for boost type AC/DC converter has been presented . Its operation and performance have been investigated through its simulation in the environment of Mat Lab. The system has been tested under various loading conditions. The obtained results showed that this fuzzy based controller can effectively control the power
