A new approach for SVPWM of a Three Level Inverter-Induction Motor Fed-Neutral Point Balancing Algorithm

open access: yes, 2011
In this paper the performance of a neutral point clamped three level voltage source inverter is investigated. The inverter feeds an electrical drive which is controlled by field oriented control (F.O.C).

Multi Level Inverter Under Unbalanced Voltage Conditions [PDF]

open access: yes, 2014
A Multilevel Inverter(MLI) is a power electronic device built to synthesize a desired A.C voltage from several levels of DC voltages. Generally unbalanced voltages will occur at supply side these can be eliminated by using Multi level Inverter.

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

open access: yesAdvanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems

open access: yesAdvanced Materials, EarlyView.
DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Photovoltaic applications for off-grid electrification using novel multi-level inverter technology with energy storage

open access: yes, 2012
In areas where grid connection is difficult and costly, the use of renewable energy is both economically and environmentally advantageous. Due to typically low system efficiency (∼10%) and intermittency of photovoltaic (PV) electricity generation, a new ...
