Abstract :
We report on a resonantly-coupled wireless power (RWPT) system for locomotion of a seat in an automobile environment. The seat moves transversely 28 cm, resulting in a time-varying geometry and coupling. In addition, the proximity of a metallic undercarriage creates the potential for interference and additional loss. We present a system that was able to achieve 80% efficiency over the entire 28 cm travel distance and was not significantly affected by the metallic environment. This work demonstrates the viability for complex RWPT systems in automotive and other complex environments.
