Photovoltaic Power Plant Collection and Connection to HVDC Grid with High Voltage DC/DC Converter

open access: yes, 2021
Photovoltaic (PV) power plant collection and connection to a high voltage direct current (HVDC) grid has many advantages. Compared with the traditional AC collection and grid-connection scheme, it can reduce the power conversion links and improve the ...

Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

open access: yesAdvanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

open access: yesAdvanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

High gain interleaved boost-derived DC-DC converters – A review on structural variations, gain extension mechanisms and applications

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy
Boost and boost-derived converters play an important role in interfacing the low voltage input from renewable energy sources like photovoltaic (PV) panels with the high voltage DC bus or DC load. Interleaved boost converters (IBC) are a separate class of

A comparison of DC- versus AC-based minigrids for cost-effective electrification of rural developing communities

open access: yesEnergy Reports, 2019
Sub-Saharan Africa continues to suffer energy poverty due to low grid expansion rates necessitated by low economic activities in those regions, sparse population distribution coupled with low household load demands, and insufficient power generation.
