Transport properties of nanosystems with conventional and unconventional charge density waves [PDF]

open access: yes, 2006
We report a systematic study of transport properties of nanosytems with charge density waves. We demonstrate, how the presence of density waves modifies the current-voltage characteristics.

Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]

open access: yesIEEE transactions on industrial electronics (1982. Print), 2015
In this paper, we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor ...

Power cable stresses caused by transmission line faults in next generation VSC-MMC systems

open access: yesThe Journal of Engineering, 2019
Until today, HVDC systems based on Modular Multilevel Voltage Source Converters (VSC-MMC) have exclusively been realised with cross-linked polyethylene (XLPE) cable transmission in monopolar configuration.

Research on 3‐D total electric field of crossing high voltage direct current transmission lines based on upstream finite element method

open access: yesHigh Voltage, 2021
The ongoing large‐scale construction of ultra high voltage direct current projects in China makes the crossing of two high voltage direct current (HVDC) lines inevitable.

Combined electrical transport and capacitance spectroscopy of a ${\mathrm{MoS_2-LiNbO_3}}$ field effect transistor [PDF]

open access: yes, 2017
We have measured both the current-voltage ($I_\mathrm{SD}$-$V_\mathrm{GS}$) and capacitance-voltage ($C$-$V_\mathrm{GS}$) characteristics of a $\mathrm{MoS_2-LiNbO_3}$ field effect transistor.

Transient voltage stresses in MMC–HVDC links – impulse analysis and novel proposals for synthetic laboratory generation

open access: yesHigh Voltage, 2018
To evaluate and optimise insulation coordination concepts for state of the art high-voltage direct current (HVDC) transmission systems, appropriate test voltage shapes are required for laboratory imitation of occurring stresses.

High Efficiency Cross-Coupled Charge Pump Circuit with Four-Clock Signals [PDF]

open access: yes, 2018
© Allerton Press, Inc. 2018A fully integrated cross-coupled charge pump circuit for boosting dc-to-dc converter applications with four-clock signals has been proposed. With the new clock scheme, this charge pump eliminates all of the reversion power loss

High voltage assisted mechanical stabilization of single-molecule junctions

open access: yes, 2017
The realization of molecular-based electronic devices depends to a large extent on the ability to mechanically stabilize the involved molecular bonds, while making use of efficient resonant charge transport through the device.

Ion channel gating: a first passage time analysis of the Kramers type [PDF]

open access: yes, 2001
The opening rate of voltage-gated potassium ion channels exhibits a characteristic, knee-like turnover where the common exponential voltage-dependence changes suddenly into a linear one.

Implications of Nonlinear Material Parameters on the Dielectric Loss under Harmonic Distorted Voltages

open access: yesEnergies, 2021
The increasing number of power electronic devices in electrical grids may lead to harmonic distorted voltages, which are considered to be possible causes of component failures. In this study, the dielectric losses of epoxy polymer and functionally filled
