Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

A novel method for estimation of IGBT switching losses in voltage source convertors through EMT simulations

2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016
This paper introduces a simplified method for estimating switching energy losses in an IGBT device of a Voltage Source Converter (VSC) using Electro-Magnetic Transient (EMT) simulations. By considering the switching process as characterized by an equivalent circuit model of a unit cell that represents one leg of a VSC, equations are derived to evaluate

Three-phase voltage-source convertor with controlled DC current for the minimisation of filter capacitance

IEE Proceedings B Electric Power Applications, 1990
The paper presents a novel control strategy for the output DC current in a three-phase AC/DC convertor using diodes, combined with a boost-type DC chopper. This contributes to the suppression of the output voltage ripples so that the size of the filter capacitor can be minimised.
