Current-Carrying Ground States in Mesoscopic and Macroscopic Systems

, 1995
We extend a theorem of Bloch, which concerns the net orbital current carried by an interacting electron system in equilibrium, to include mesoscopic effects.

Real-Time Inductance Estimation of Sensorless PMSM Drive System Using Wavelet Denoising and Least-Order Observer with Time-Delay Compensation

Machines
In this paper, the inductance of a sensorless PMSM (Permanent Magnet Synchronous Motor) drive system equipped with a periodic load torque compensator based on a wavelet denoising and least-order observer with time-delay compensation is estimated in real ...

Self-Tuning Inductance-Oriented Model-Free Predictive Current Control for Tidal Stream Turbines

Journal of Marine Science and Engineering
Tidal energy is increasingly harnessed due to its high energy density, substantial reserves, and reliable predictability. However, marine fouling on turbine blades adds weight and induces asymmetric system loads; prolonged operation exacerbates generator

Two-dimensional model of intrinsic magnetic flux losses in helical flux compression generators

, 2012
Helical Flux Compression Generators (HFCG) are used for generation of mega-amper current and high magnetic fields. We propose the two dimensional HFCG filament model based on the new description of the stator and armature contact point.

An Inductance Identification Method for Robust Position Sensorless Control to Magnetic Saturation of IPMSMs

IET Electric Power Applications
A position sensorless control method for interior permanent magnet synchronous motors (IPMSMs) has been developed to reduce cost and improve reliability. The performance of position estimation largely depends on the motor parameters.

Modeling and Experimental Validation on Current Uniformity Characteristics of Parallel Spiral Structure Surge Arrester in ±550 kV DC GIS

Applied Sciences
The employment of a multi-column parallel connection is intended to enhance the energy absorption capability and reliability of surge arresters. However, the disparity in reference voltage between each varistor column and the uneven current distribution ...

The Influence of Frequency upon the Self-Inductance of Coils

Proceedings of the American Academy of Arts and Sciences, 1906
It is well known, through the work of Lord Rayleigh,1 and Stefan,2 , that currents of high frequency in straight wires distribute themselves over the cross-section of the wires very differently from steady currents. The values of the resistance of such wires, as well as their self-induc tance, thereby suffer a change.
