This article describes the ways to preserve resonant mode in biparametric circuits with distributed parameters and studies effect of changes circuit power supply on mode. During moving part’s movement sensor due influence magnetic resistance steel part circuit, law change electrical inductance (distribution flux long conductors) differs from linear one.

The electric current is omnipresent and indispensable in our life. But there are always threatening dangers connected with it. One of them is the electric short circuit and we have to protect people and facilities from its effects. This protection is often provided by power circuit breakers or motor protective circuit breakers. These devices are able to detect the short circuit, limit the curre...

Abstract: This paper proposes a five-degree-of-freedom (5-DOF) hybrid magnetic bearing (HMB) for direct-drive wind turbines, which can realize suspension in the 4-DOF radial and 1-DOF axial directions. Only two sets of radial control windings are employed in the proposed HMB because only one set of radial control windings can achieve the 2-DOF suspension in the radial direction. Unlike the trad...

This work presents investigations and detailed analysis of ringing in a non-resonant pulsednuclear magnetic resonance (NMR) circuit. Ringing is a commonly observed phenomenon in high power switching circuits. The oscillations described as ringing impede measurements in pulsed NMR systems. It is therefore desirable that those oscillations decay fast. It is often assumed that one of the causes be...

The dynamic characteristics of an axisymmetrical linear actuator with axially magnetized moving permanent magnet are obtained using combined field and circuit approach. The magnetic field of the actuator has been analysed using the finite element method over a current-displacement sampling grid. Two field analyses are carried out for each point of the grid one for the real system and one for th...

Superconducting Josephson junctions and quantum phase slip (QPS) create various hybrid circuits combined with nonsuperconducting elements. Those require a common analysis method to bridge the gap between superconducting electronics. This article presents an electromagnetic-flux-distribution model unify analyses of non-superconducting circuits. uses electric magnetic fluxes as variables definiti...

The nowadays performance limiting power dissipation due to leakage has become a critical burden. A simple way to reduce power dissipation is to shut down idle circuit parts. However, when hibernated circuit parts are activated again, their previous state must be recovered. In order to avoid energy and time consuming recovery cycles non-volatile elements must be added to realize the desired inst...

In this paper, we evaluated the characteristics of the magnetic core loop antenna that is used to receive long wave radio signals for time standards. To evaluate the receiving sensitivity of the antenna, we calculated the antenna factor of the magnetic core loop antenna by combining a magnetic field simulation and a circuit simulation. The simulation results are in good agreement with the resul...
