An Improved Model Parameter‐Free Predictive Control With Fast Gradient Updating for Three‐phase Three‐Level Inverters

open access: yesIET Power Electronics
Look‐up‐table (LUT) based model parameter‐free predictive control (MFPC) suffers from long update time and large storage requirement, particularly when applied to multi‐level inverters.

Resolving Heterogeneity of Targeted Lipid Nanoparticles Through Solution‐Based Biophysical Analyses

open access: yesAdvanced Materials, EarlyView.
AF4‐UV‐DLS‐MALS‐SAXS resolves previously inaccessible targeted lipid nanoparticle (tLNP) subpopulations that differ in size, shape, and composition. Correlation of subpopulation‐resolved biophysical properties with in vivo RNA delivery reveals that targeted placental transfection is associated with distinct tLNP subpopulations rather than ensemble ...

Doubly grounded buck‐boost PV grid‐connected inverter without shoot‐through problem

open access: yesElectronics Letters
Transformerless grid‐connected inverters (GCIs) are universally utilized in the PV system. However, they have the shoot‐through issue and common mode leakage current (CMLC).

Electrically Coded Retinomorphic Spectrophotodetector

open access: yesAdvanced Materials, EarlyView.
Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

A family of Z‐source‐based half‐bridge inverters: Topology derivation

open access: yesIET Power Electronics
Z‐source‐based half‐bridge inverters are a type of Z‐source inverters whose outer stage is a half‐bridge inverter. This paper presents a generalized structure from which 16 configurations can be derived. Once this topology has been introduced, one of the

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature

open access: yesAdvanced Materials, EarlyView.
We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

The use of optocouplers for achieving synchronization in thyristor controllers13; [PDF]

open access: yes, 1980
The optocouplers replace the synchronization transformers to simplify the synchronizing circuits in AC/DC convertors and in AC power controllers. Simple circuits are described for synchronization of 1-amp;phi; and 3-amp;phi; control circuits. The methods
