In this work we propose a method for maximization of the efficiency of an underwater wireless power transfer system that has to cope with load changes, quality factor and coupling coefficient deviations. By means of 3D electromagnetic simulation and numerical computation, parameter analysis is accomplished using different compensation methods, namely series-series, series-parallel and parallel-parallel...
In wireless power systems for charging battery-operated devices, the selection of component values guaranteeing certain desired performance characteristics can be a tedious trial-and-error process, either sweeping component values in circuit simulations or changing components by hand. This difficulty is compounded by the variable nature of the load resistance presented by a device under charge. This...
The significance of passive RFID labels is growing in logistic processes. While the initial aim was to identify items with an invariable identification code, new applications with enhanced functionality arise which need additional energy. This contribution investigates the requirements on an inductive coupled RFID radio link in order to provide a reliable power transmission under varying coupling...
Inductive coupling is a common way to wirelessly transmit data to medical implants. In such applications, the carrier frequency is often limited to tens of MHz which is able to well penetrate the skin. To achieve high data rate, the number of carrier cycles used to modulate each bit should be as small as possible. This usually requires lowering the quality factor (Q) of the data transmission network,...
