Feasible evaluations of coupled multilayered chip inductor for POL converters

open access: yes, 2015
Point of load (POL) converters require a small size and high-efficiency performance for IT industrial applications. In addition, the interleaved technique, magnetic integration, and application of GaN FETs are well known as good approaches to satisfy ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Coupled inductor filter with frequency notching characteristics for grid interface

open access: yes, 2014
A novel design of a power grid interface using a coupled inductor filter with a frequency notching characteristic is presented in this paper. Traditional grid-tie power converters are connected to the supply grid via an L filter, an LC filter or an LCL ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Hybrid Switched Capacitor Three Winding Coupled Inductor High Step-Up DC-DC Converter

open access: yesIEEE Access
Switched capacitor cells have been studied in recent years. These approaches allow different new topologies to be generated. One such technique is the hybrid converter, where a coupled inductor and switched capacitor can be combined. Thus, in this paper,

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

A Coupled Inductor Based High Voltage Gain DC-DC Converter Using Interleaved Voltage Multiplier Cells

open access: yesIranian Journal of Electrical and Electronic Engineering, 2020
In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor.

Modeling a Coupled-Inductor Boost Converter in the Complementarity Framework

open access: yes2012 Sixth UKSim/AMSS European Symposium on Computer Modeling and Simulation, 2012
We consider the modeling of switching circuits, consisting of passive elements, independent sources, which are subject both to externally induced switches (time events) and to state events. We focus on the use of the complementarity formalism for obtaining such hybrid (actually piecewise linear) models, assuming idealized current- voltage ...
