RF bifurcation of a Josephson junction: microwave embedding circuit requirements

open access: yes, 2006
A Josephson tunnel junction which is RF-driven near a dynamical bifurcation point can amplify quantum signals. The bifurcation point will exist robustly only if the electrodynamic environment of the junction meets certain criteria.

The Influence of Excitation Inrush Current on the Second Harmonic Characteristics of Doubly Fed Induction Generator

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Considering the no‐load closing of a transformer in the adjacent substation of a wind farm as the research background, this study investigated the harmonic distortion in the voltage at the point of common coupling caused by the inrush current. By quantitatively analysing the transient response of the stator and rotor flux linkage of the wind turbine ...

A Cost‐Effective Approach for Temporary Operation of Medium‐ and High‐Voltage Electric Motors Incorporating Damaged Stator Coils

open access: yesIET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This paper proposes an approach to remove the damaged coil from the stator.The functional characteristics of the electric motor in different modes are analysed using finite element software. ABSTRACT Stator inter‐turn and ground faults in medium‐ and high‐voltage (MV/HV) motors often require full stator rewinding, causing long outages and high costs ...

The analysis of the threshold value of the complex short-circuit ratio index and its significance in the context of static voltage stability

open access: yesFrontiers in Energy Research
The short-circuit ratio index (SCR) can effectively quantify the voltage support strength in traditional DC grid-connected scenarios, yet it cannot reasonably describe the voltage support strength in diverse device grid connection scenarios.

Online Identification of Thevenin Equivalent Circuit Model Parameters and Estimation State of Charge of Lithium-Ion Batteries [PDF]

open access: yes2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018
On Electrical and Hybrid Vehicles (EVs, HEVs), energy is stored in accumulators, mainly electro-chemical batteries. A reliable and cost effective management of energy storage system is a key point for the development of such devices, their durability and for vehicle performance optimization.
