A novel controller has been proposed to regulate the power flow in BD-WPT systems. The proposed controller, located on the pickup side, utilizes measured active and reactive power generated by the pickup converter to establish precise synchronization between the primary and pickup as well as to regulate the power flow in both directions without a dedicated communication link.The novel PQ based control technique has been described in detail, analysing its sensitivity to variations in system parameters. Simulated and experimental results of a prototype 1-kW BD-WPT system have been presented to demonstrate the applicability and robustness of the proposed controller.
