Triple Line-Voltage Cascaded VIENNA Converter Applied as the Medium-Voltage AC Drive

open access: yesEnergies, 2018
A novel rectifier based on a triple line-voltage cascaded VIENNA converter (LVC-VC) was proposed. Compared to the conventional cascaded H-bridge converters, the switch voltage stress is lower, and the numbers of switches and dc capacitors are fewer under

Three-Phase Trinary Asymmetric Multilevel Inverter With Single DC Source and Open-Loop Control

open access: yesIEEE Open Journal of Industry Applications, 2021
A three-phase trinary-asymmetric cascaded H-bridge multilevel inverter topology with single dc source per phase is presented in this paper. Only one of the H-bridges (called Main bridge) is fed from a dc source and all others (called auxiliary bridges ...

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

FCS-MPC for four-switch three-phase AC-DC converters with DC-link capacitor voltage balancing

open access: yesJournal of Measurement Science and Instrumentation, 2019
Due to the decrease in the number of switches for the four-switch three-phase alternating current-direct current(FSTP AC-DC) converter, it can easily lead to DC-link capacitor voltage imbalance and the system stability reduction.

Common-Mode Resonance Damping and DC Voltage Balancing Strategy for LCCL-Filtered Three-Level Photovoltaic Grid-Tied Inverters

open access: yesIEEE Access, 2020
The leakage current caused by common-mode (CM) voltage is a critical issue in transformerless three-level photovoltaic (PV) inverters, which can increase the output current distortion, bring extra power losses, aggravate the electromagnetic interference,

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...
