In this paper, analytical and semi-analytical formulas are presented for the self- mutual inductance of thin ordinary disk coils Bitter coils. The lie concentrically in a plane. with constant current density. density carrying disc is not uniform across its cross-sectional area, but it function ratio inner diameter to an arbitrary radius within disk. we show possibility calculate self-inductance...

This article proposes a circuit model (CM) to calculate the current along printed coils used in resonant wireless power transfer (RWPT). It considers system composed of metamaterial and two coplanar coils, transmitter (Tx) receiver (Rx), respectively. First, CM for is presented. Then, an analytical proposed self-inductance inductors, their characteristic resistance, mutual inductance between co...

A dc-excited Vernier reluctance machine (DC-VRM) using a 12-slot/10-pole-pair design exhibits the advantages of small torque ripple and robust structure, which has good potential to be applied as an aerospace integrated starter/generator. By eliminating vulnerable position sensors, system reliability can further improved by sensorless startup. However, driven traditional three-phase inverter, p...

Data are presented on mutual and self-inductance of various inductors used in multilayered superconductor integrated circuits: microstrips striplines with widths from 250 nm to a few micrometers, located the same layer at distances each other, and/or different layers spaced vertically; effect long slits ground plane(s) along their inductance; inductance right-angled bends; meanders. Measurement...

An LCC/SP self-tuning wireless charging system is proposed herein for use in a test bench. With different dislocations addition to changes the coil self-inductance and mutual inductance caused by secondary magnetic shielding materials, can ensure that high power factor of primary side remains unchanged without changing circuit topology. Based on this normalized detuning model, switch-controlled...

Wireless power transmission (WPT) is commonly used today in many important daily applications, such as electric vehicles, mobile phones, and implanted medical devices. The transmitter receiver coils are essential elements the WPT system, coupling coefficient between these plays an role increasing transfer efficiency. In this work, we introduce a new approach to optimizing by changing geometries...

This new LCR Meter is especially designed for measurements of low-value components in integrated circuits and thinJilm hybrid circuits, as wellas of discrete components. /t uses a four-pair measurement technique to reduce errors caused by stray capacitance, residual inductance, and mutual inductance of the tesf /eads. T N THE MANUFACTURE of integrated circuits, I good process control is essenti...
