Efficient Multi-Port Bidirectional Converter With Soft-Switching Capability for Electric Vehicle Applications

open access: yesIEEE Access, 2021
In this paper, to solve the hard-switching operation problem and the lack of existing a bidirectional power flow path from output to the energy storage device of the conventional three-port converter, a new soft-switched bidirectional multi-port ...

A novel passive snubber soft-switching inverter

open access: yesDianzi Jishu Yingyong, 2018
An improved simple passive snubber inverter is proposed in order to solve the problem of complicated snubber circuit in the traditional soft-switching topology. Only a few passive components are used in the novel topology.

Research on efficiency optimisation of DAB converters considering current stress and soft‐switching

open access: yesIET Power Electronics, 2022
To solve the problem of low efficiency of the dual active bridge (DAB) converter under the traditional single‐phase‐shift control, a natural soft‐switching current stress optimisation (NSS‐CSO) method is proposed by considering the current stress ...

Soft-switching SiC interleaved boost converter [PDF]

open access: yes2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
A DC-DC converter topology is presented combining the soft switching effects of the Snubber Assisted Zero Voltage and Zero Current Transition (SAZZ) topology and the increased inductor frequency of the dual interleaved boost converter with interphase transformer. The snubber capacitors and output capacitances of the main devices are discharged prior to

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Parameter optimization strategy of LLC converter soft start-up process based on a simplified numerical calculation model

open access: yesEnergy Reports, 2023
High-frequency start-up strategy is usually used to limit the current overshoot in the resonant tank of LLC converter. However, the strong coupling among start-up frequency, initial duty cycle, and current limit increases the design complexity of ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
