Multipath Miller Compensation for Switched-Capacitor Systems [PDF]

open access: yes, 2011
A hybrid operational amplifier compensation technique using Miller and multipath compensation is presented for multi-stage amplifier designs. Unconditional stability is achieved by the means of pole-zero cancellation where left-half zeros cancel out the ...

The Impact of Various Contact Structures on the Microscopic Surface Condition of Vacuum Interrupters During Capacitive Switching

open access: yesHigh Voltage, EarlyView.
ABSTRACT The double‐break vacuum circuit breakers (VCBs) that utilize series break technology effectively increase the switching capability for capacitive currents, elevate the withstand voltage level, and reduce the likelihood of restrike, all without compromising the breaking capacity for short‐circuit currents.

Microscopic Stress Analysis of Silicon Carbide Devices Under Overcurrent Conditions in DC Solid‐State Circuit Breakers

open access: yesIET Smart Energy Systems, EarlyView.
A coupled Saber–TCAD–thermo‐mechanical simulation framework is proposed to evaluate microscopic stresses in SiC MOSFETs under overcurrent operation. Ultrahigh gate‐voltage driving reduces thermal and mechanical stress but increases gate oxide electric‐field stress, revealing a reliability tradeoff for DC solid‐state circuit breakers.

DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis

open access: yesJournal of Applied Crystallography, EarlyView.
DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.

Folklore Studies, Fieldwork and the Making of a Domestic Anthropology in Fin‐de‐Siècle Britain

open access: yesHistory, EarlyView.
Abstract This article follows the ‘communities of knowledge‐making’ that formed around folklore collection at the end of the nineteenth century. Often regarded as eccentric or marginal figures in the history of human science, these collectors in fact engaged in lively and sophisticated discussions about the methodologies needed to study the mental ...

Flying-capacitor-based chopper circuit for dc capacitor voltage balancing in diode-clamped multilevel inverter

open access: yes, 2010
This paper proposes a flying-capacitor-based chopper circuit for dc capacitor voltage equalization in diode-clamped multilevel inverters. Its important features are reduced voltage stress across the chopper switches, possible reduction in the chopper ...
