We characterize inductors fabricated from ultra-thin, approximately 100 nm wide strips of niobium (Nb) and niobium nitride (NbN). These nanowires have a large kinetic inductance in the superconducting state. The kinetic inductance scales linearly with the nanowire length, with a typical value of 1 nH µm(-1) for NbN and 44 pH µm(-1) for Nb at a temperature of 2.5 K. We measure the temperature an...

Effects of magnetic saturation on various equivalent circuit models of an induction motor are studied. The parameters of 2.2-kW and 37-kW motors with closed rotor slots are analyzed using finite element computations. Both skewed and unskewed rotor slots are studied. The magnetizing inductance not only depends on the main flux, but is also dependent on the rotor current, especially if the rotor ...

In previous work, a closed form expressions for the series line impedance per unit length of a single and multiple coupled interconnects on lossy silicon substrate were presented. In this paper, the induced current density distribution inside silicon substrate and quasi-static Green's function approach were used to derive the frequency-dependent closedform expression for the internal inductance...

This paper presents the inductance–capacitance (LC) resonance effect in the magnetoelectric (ME) composites characterization system. The measured magnetoelectric voltage coefficient is significantly affected by the LC resonance at the electromechanical resonant frequency, but not at 1 kHz, typically reported in the literature. Decreasing the measuring circuit inductance and/or capacitance helps...

A new electronically-controllable lossless floating inductance (FI) circuit (without any matching condition) has been presented, which employs only one Voltage Differencing Current Conveyor (VDCC), one grounded capacitor and one grounded resistor. The main aim of the paper is to present a new floating inductance simulator using single active device with minimum passive components. The proposed ...

In this paper a voltage controlled current conveyor is presented wherein the intrinsic transresistance is controlled by a voltage variable current source which is realized using floatinggate MOSFETs. The resultant conveyor has been used to implement an impedance converter which is further used as inductance simulator. The characteristics of the conveyor and inductance simulation have been obtai...

An active circuit is described that exhibits the equivalent reactance of a negative inductor. In contrast with previous techniques based on negative impedance converters, the negative inductance is produced by generating an opposing time-varying magnetic flux. The new circuit also enables the inductance to be electronically varied between negative and positive values, can enhance the Q, and def...

In this research we investigated the effects of toroidal field ripple of tokamak on the plasma internal inductance. For this purpose, array of magnetic probes and also a diamagnetic loop with its compensation coil were designed, constructed, and installed on outer surface of the IR-T1 tokamak. Amplitude of the TF ripple is obtained 0.01, and also the effect of the TF ripple on the plasma intern...

One challenge to predict output performance characteristics of switched reluctance machines (SRM) is the accurate estimation of the minimum inductance of the stator phase at unaligned position of the rotor. In this paper, boundary element method (BEM) is used for this purpose while avoiding time-consuming numerical integrations. So, the method is investigated in terms of accuracy and computatio...
