Modulation Technique for Modified Active Quasi-Z-Source Inverter with Common-Mode Voltage Reduction
, 2021 In Z-source topologies, a high-amplitude common-mode voltage can occur when shoot-through states are inserted. In this study, a new space vector pulse-width modulation for an active quasi-Z-source topology is proposed to operate at a high modulation ...

A New Quasi Z-Source Dynamic Voltage Restorer [PDF]
Journal of International Council on Electrical Engineering, 2011 Abstract –This paper deals with a new quasi Z-source Dynamic Voltage Restorer(DVR). The proposed system based on single-phase quasi Z-source AC-AC converter which has features such as the input voltage and output voltage are sharing ground, and the input current operates in continuous current mode.

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography
Advanced Functional Materials, EarlyView.In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Advanced Functional Materials, EarlyView.A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...
