Inductive Link Design

Abstract

An inductive link is created fairly easily: two coils are all that is essentially needed. Even in a far from perfect design, some signal and hence power will be coming through. The rudimentary approach of picking the largest coils available that fit the application, with an arbitrary winding type and number of turns, may in many cases satisfy the requirements. Designing an inductive link that maximises the amount of power transmitted or the operating range within the constraints of the application however, is an entirely different story.
