This paper overviews theoretical and practical design issues related to inductive power transfer systems and verifies the developed theory using a practical electric vehicle battery charger. The design focuses on the necessary approaches to ensure power transfer over the complete operating range of the system. As such, a new approach to the design of the primary resonant circuit is proposed, whereby deviations from design expectations due to phase or frequency shift are minimized. Of particular interest are systems that are neither loosely nor tightly coupled. The developed solution depends on the selected primary and secondary resonant topologies, the magnetic coupling coefficient, and the secondary quality factor.read more

Wireless fleet charging system for electric bicycles
TL;DR: In this paper, a double coupled inductive system for multi-pickup systems was proposed for wireless charging of a fleet of electric bicycles, where an intermediary coupler is introduced between the primary and pickup and operates as a switch, with the intention of turning on when the bicycle is present and turning off when absent to prevent magnetic fields from radiating into the environment.
