Multi-Turn, Printed Surface Coil Inductance, and Q OptimizationI200 1100 1000 900 800Ahmad RaadSiew Kan
Inductance values are measured though the use of a charge transfer based measurement system. During a first phase, a target inductor is connected to an energy source to allow curren
The eddy currents produced are related to the distance (d) size and composition of the conductive target approaching. The eddy currents, in turn, generate their own magnetic field, that will oppose the field generated by the coil/inductor. A transformer behaves like this where its primary core ...
In a favoured winding arrangement, said at least one secondary or sense winding has first and second coils, said coils being connected so that in the presence of said forward or drive field the voltage induced in the second coil in the absence of said at least one conductive screen is subst...
calculator, I have added one such type to this list. Talking about the types of coils,N turn circular loop, circular toroid, multi-layer square solenoid, single-layer square solenoid, one turn loop coil, One-layer noncircular with winding pitch, etc. are available in some inductance ...
coil optimizationWheeler's empirical inductance formula for a multi-turn, close-wound flat coil shows that the maximum inductance for a given length of wire occurs when the outer to inner radius ratio is equal to 15/7. A similar expression is proposed for a flat, printed spiral for surface ...
