Abstract

The efficiency of an inductive power transfer (IPT) system is highly dependent on load resistance. The efficiency decreases rapidly when the load resistance deviates from its optimal value. In this study, a new maximum efficiency point tracking (MEPT) control method for a series-series tuned IPT (SS-IPT) system is proposed. The equivalent load resistance of the SS-IPT system is controlled to the optimal value, which maximizes overall system efficiency regardless of the output power. Since the proposed MEPT controller uses estimated dynamic states of the voltage and current of the receiver coil, there is no need to use wireless communication and voltage and current sensors on the receiver-side.
