A Survey on Topologies and Controls of Z-Source Matrix Converter [PDF]

open access: yes, 2019
This paper describes the Z-source matrix converter (ZS-MC) topology which specifically discusses topology and control on the ZS-MC. There are two topologies on the ZS-MC, namely Z-source direct-MC (ZS-DMC) and indirect-MC (ZS-IMC). The difference of each

Oxygen Evolution Reaction Catalysts for Acidic‐Media CO2 Electrolyzers

open access: yesAdvanced Materials, Volume 38, Issue 19, 1 April 2026.
Acidic‐media CO2 electroreduction (CO2R) could decarbonize chemical production, despite relying on rare‐earth elements for anodic oxygen evolution reaction (OER). Transferring the learnings from mature sister technologies (water electrolysis) could accelerate technological development.

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

Z-Source Matrix Converter: An Overview [PDF]

open access: yes, 2016
Conventional matrix converters (MCs) have limited voltage gain that is less than 0.866, whether for direct MC (DMC) or indirect MC (IMC). The Z-source MCs (ZSMCs) overcome the voltage gain limitation of the traditionalMC and achieve buck and boost ...

GA-Based Optimal LQR Controller to Improve LVRT Capability of DFIG Wind Turbines

open access: yesIranian Journal of Electrical and Electronic Engineering, 2013
Nowadays, the doubly-fed induction generators (DFIGs) based wind turbines (WTs) are the dominant type of WTs connected to grid. Traditionally the back-to-back converters are used to control the DFIGs.
