Modeling and practical evaluation of a class-E amplifier with a three-coil inductive link

This paper presents the state-space modeling of a system consisting of a class-E amplifier and an inductive link with three coils, featuring a reading unit and a sensor unit. From the developed model, it was possible to carry out a series of simulations in order to evaluate and improve the system performance before its implementation. The inductive link is able to perform the energy transfer from the reading unit to the sensing unit, in order to supply power to a given load in the sensing unit. The class-E amplifier and inductive link were implemented and the results showed that it is possible to supply a low power microcontroller and a sensor with the class-E amplifier at a supply voltage of 15V for a maximum distance of 30 mm between the reading and sensing unit coils.
