Design and Implementation of Modular Transmitter Tracks for Dynamic Wireless Power Transfer Systems With Stable Coupling and Outputs

This paper introduces a modular transmitter track design methodology for dynamic wireless power transfer (DWPT) systems to mitigate the issue of unstable coupling coefficients during receiver movement. Each transmitter track employs a streamlined, cost‐effective partially overlapping rectangular coil integrated with an LCC compensation network, while the receiver coil is also compensated by an LCC circuit to enhance coupling stability. Beyond the conventional rectangular track design for straight trajectories, this work proposes innovative design approaches for joint tracks accommodating curved and ascending paths. Both simulation and experimental results validate the effectiveness of the proposed design methods, demonstrating consistent coupling performance across various configurations. A practical LCC‐LCC‐compensated DWPT system incorporating the proposed track design achieves stable output currents, with fluctuations constrained to less than 6.3% as the receiver navigates various trajectories.
