Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

International Journal of Circuit Theory and Applications, EarlyView.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

RORγt‐APCs: The New Masters of Oral Tolerance

Barrier Immunity, EarlyView.
ABSTRACT Oral tolerance is defined by the hypo‐responsiveness of our body to fed antigens, and its failure can lead to immune‐mediated diseases, such as allergy, chronic inflammation and autoimmune diseases. Decades of research have demonstrated that antigen‐presenting cells (APCs) promote oral tolerance by inducing regulatory T cells (Tregs) and/or ...

VARC - A Cost-Effective Ultrafast DC Circuit Breaker Concept

, 2018
A concept for a dc circuit-breaker is proposed. A vacuum interrupter is used together with a resonant circuit excited by a power electronic converter to create a zero-crossing in the interrupter current.

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Atomic Scale Insight Into High Voltage Degradation Mechanism in YSZ Electrolyte for Solid Oxide Electrolyzer Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The evolution of yttria‐stabilized zirconia (YSZ) electrolyte microstructure after testing at progressively high voltages was captured at the micro‐ and atomic‐scale levels to determine the operational boundaries of a solid oxide electrolysis cell (SOEC).
