Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

Advanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Decentralized Interleaving of Resistively Coupled Parallel Hysteresis-Controlled DC-DC Converters

IEEE Open Journal of Power Electronics
Current sharing and ripple reduction remain key challenges in parallel-connected DC-DC converters. This paper presents a decentralized strategy for achieving interleaving of the control signals in non-isolated DC-DC converters connected in parallel, with

Analysis of inductor current sharing in nonisolated and isolated multiphase dc-dc converters

, 2007
Current sharing among inductors is an important issue in both isolated and nonisolated dc-dc converters. In this paper, average current sharing is in-depth modeled and analyzed for both interleaved multiphase buck converters and isolated current-doubler ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

Advanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Reachability Analysis of Transformer-Isolated DC-DC Converters

Various mission-critical applications necessarily require a transformer in switching converters to obtain DC isolation between the converters’ input and output. Since DC-DC converters are the switching devices, these are modeled as hybrid automata.

A Miniaturized Autonomous Thermomagnetic Generator

Advanced Functional Materials, EarlyView.
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Unified Small-Signal Modeling of Non-Isolated High Step-Up Converters Based on the Multistate Switching Cell

Energies
This work introduces a systematic small-signal modeling framework for a family of non-isolated high step-up dc–dc converters based on the multistate switching cell (MSSC) operating in continuous conduction mode (CCM). By analyzing the current and voltage
