Tapped Switched-Coupled-Inductors Γ-Source Inverter

, 2019
This paper introduces a novel tapped switched-coupled-inductors Γ-source inverter (TSCL-ΓSI) with modified cell and high voltage boost ability. Unlike Γ-source inverter, input current in proposed topology is continuous which eliminates enormous inrush ...

Triple-Voltage Gain and Self-Balancing in a New Switched-Capacitor Seven-Level Inverter for Microgrid Integration

Energies
In the context of power electronic interfaces in photovoltaic (PV), fuel cell, battery, and microgrid applications, the low output voltage of the DC source necessitates a voltage-boosting inverter. This paper proposes a single-source seven-level switched-

Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, EarlyView.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst

Improved predictive current control technique for a zero current switched buck-boost series resonant inverter

, 1993
An improved predictive current control technique for a zero current switched (ZCS) buck-boost series resonant inverter (SRI) is proposed to overcome the inherent disadvantages such as the uncontrollable large overshoot and the large current ripple. Using

An Improved and Efficient High-Boost Switched Capacitor Multilevel Inverter

Power Electronics and Drives
This paper presents a fundamental nine-level switched-capacitor multilevel inverter (CSMLI) powered by a single DC source. The configuration employs two capacitors, nine switches, and one diode to generate nine distinct output voltage levels. It achieves

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

Angewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Development of switched reluctance drive inverter / Abd Lated Ishak [PDF]

, 1995
This project investigates a modified single-phase switched-reluctance drive inverter. The inverter uses two switches as the conventional half-bridge type but commutation is controlled by a thyristor and capacitor.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
