Optimum Design of a Multiple-Active-Bridge DC–DC Converter for Smart Transformer

IEEE transactions on power electronics, 2018
The modular smart transformer (ST) is composed by several basic converters rated for lower voltage and power. In this paper, the quadruple active bridge (QAB) is used as the basic block for the modular ST. In this application, the efficiency and cost are

Effect of Optical Illumination on Bubble Nanodomains

Advanced Functional Materials, EarlyView.
Stable surface‐confined nanoscale bubble domains are created and manipulated in PMN‐PT single crystals. Under above‐bandgap illumination, these bubble nanodomains remain unchanged. However, upon illumination cessation, they rapidly expand to switch the entire crystal surface, due to the accumulation of a large reservoir of electrons at the crystal ...
