Robust Controller Design for Phase-Shifted Full-Bridge Series Resonant Converter under the Nonlinear Load

, 2015
In this paper, a third-order sliding mode control (3-SMC) scheme is proposed for the phase-shifted full-bridge series resonant converter (PSFB-SRC) which has a nonlinear characteristic and experiences the nonlinear load variation when it is used in DC/DC

From patient advocacy to patient‐driven research: Building active partnerships beginning at the bench to reach the bedside

FEBS Open Bio, EarlyView.
Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

A Novel Phase‐Shifted Modulation for Balancing Current Stress During Startup of High‐Power Full‐Bridge DC/DC Converters

The Journal of Engineering
Traditional duty‐cycle or phase‐shift modulation is inadequate for achieving a balanced current‐stress distribution during the startup of full‐bridge DC/DC converters. As converter power capacity increases, these limitations not only restrict the startup

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Operation Modes of a Secondary-Side Phase-Shifted Resonant Converter

Energies, 2015
In this work, a unidirectional full-bridge resonant converter with secondary-side phase-shifted control is addressed. With the variation of voltage gain and power level, this converter may enter into different operational modes, including three ...

A New Full-Bridge Converter with Phase-Shifted Coupled Inductor Rectifier

, 2019
A conventional phase-shifted full-bridge (PSFB) converter is one of the most promising topologies in high power/high efficiency applications because of its small RMS current, inherent zero-voltage switching (ZVS) capability, and clamped voltage stress of

Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

FEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

A Novel Choice Procedure of Magnetic Component Values for Phase Shifted Full Bridge Converters with a Variable Dead-Time Control Method

Energies, 2015
Magnetic components are important parts of the phase shifted full bridge (PSFB) converter. During the dead-time of switches located in the same leg, the converter can achieve zero-voltage-switching (ZVS) by using the energies stored in magnetic ...
