Control of an Inductive Power Transfer System Using a Double Coil Structure

This paper presents the design of control system using a double DD coil structure. The is layered structure that consists two single coils, rotated to each other by 90°. A large-signal and small-signal model proposed IPT are designed for synthesis. derived from harmonic approximation extended describing functions (EDF). For model, voltage current schemes were purpose wireless battery charging. robustness tested on small-scale coils resistive load. results evaluated at different reference voltages, currents, loads coupling coefficients.
