Experimental Characterization and Validation of a PLECS-Based Hardware-in-the-Loop (HIL) Model of a Dual Active Bridge (DAB) Converter

open access: yesEnergies
Hardware-in-the-loop (HIL) simulation is an essential tool for rapid and cost-effective development and validation of power-electronic systems. The primary objective of this work is to validate and fine-tune a PLECS-based HIL model of a single dual active bridge (DAB) DC-DC converter, thereby laying the foundation for building more complex models (e.g.,

Impedance Shaping of Isolated Two-Stage AC-DC-DC Converter for Stability Improvement

open access: yesIEEE Access, 2019
The isolated two-stage ac-dc-dc converter containing an isolated dual-active-bridge (DAB) dc-dc converter and an ac-dc rectifier has been widely used for connecting the dc sources to the ac utility grid. However, the impedance interaction between the DAB

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.

Performance Evaluation of the FCI-DAB as a Single-Stage and Storage Capacitorless PFC Wireless Charger

open access: yesIEEE Access
This paper compares two single-stage (1-S) topologies for Electric Vehicle (EV) wireless battery chargers. The Single Stage Resonant-Dual Active Bridge (SSR-DAB) topology is a very compact topology due to the lack of input and output interfaces, reducing

Grid‐Forming Converter for DC Microgrid With Virtual Separately Excited DC Machine Control Strategy and Dual Active Bridge (DAB) Converter

open access: yesIET Power Electronics
ABSTRACT Inertia, or the rotor stored energy of large rotating machines, plays an essential role in power systems' flexibility, resilience and stability. According to the generation process based on renewable energy and the proximity of generation and consumption, bulky synchronous generators (SGs) are replaced with low or no inertia ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Active Power Regulation Through Dual Active Bridge Converter in Microgrids Employing MCPT-Based Adaptive Dual Phase Shift Controller: Comparative Analysis

open access: yesInternational Transactions on Electrical Energy Systems
In this work, an adaptive dual phase shift (DPS) controller based on minimum current point tracking (MCPT) is introduced. The dual active bridge (DAB) converter is employed for regulating the active power in the microgrid whereas the propounded ...

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System

open access: yesAnnals of Neurology, EarlyView.
Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.
