Design and Simulation of an Autotransformer‐Based 18‐Pulse AC‐DC Converter for Enhanced Power Quality in Vector‐Controlled Asynchronous Motor Drives

Energy Science &Engineering, EarlyView.
18‐pulse AC/DC converter with T‐connected autotransformer for feeding VCAMD. ABSTRACT Reducing harmonics in alternating current (AC) input and ripples in direct current (DC) output enhances power quality, achievable through multi‐pulse converters (MPCs). This study presents the design, simulation, and analysis (in MATLAB/Simulink) of an autotransformer‐

Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

Geological Journal, EarlyView.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

Heat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...
