title = "A Novel Control Method of Maximum Efficiency Point Tracking for Series-Series Wireless Power Transfer System",
abstract = "The efficiency of an inductive power transfer (IPT) system is dependent on its equivalent load. Specifically, the efficiency decreases very rapidly as the output power decreases. In this study, a maximum efficiency point tracking (MEPT) controller for a series-series tuned IPT (SS-IPT) system is proposed. Based on the load voltage and current observers in the literature, the equivalent load is controlled to a rated value that makes the efficiency to its maximum irrespective of the output power of the SS-IPT system. The proposed MEPT controller is designed by considering the cross-coupled and cascaded relationships between the state variables defined by the synchronous rotating reference frame (RRF) model of the SS-IPT system. Since the proposed MEPT controller utilizes estimated dynamic states by the state observers in the literature, voltage and current sensors of the receiver coil and the wireless communication are not required.",
