Inductive power transfer (IPT) light-emitting diode (LED) lighting systems have many advantages in commercial, industrial, and domestic applications. Due to the large leakage inductance, primary and secondary capacitor compensations are necessary to improve the power transfer capability. To offer a direct current source output for LED driving, topology with series-series (SS) compensation is chosen and analyzed in this paper. Using a properly designed operating frequency, the SS compensation can be the best topology for the voltage-source-input and current-source-output applications. To design an efficient IPT system, the loosely coupled transformer is the key component whose design and interaction with other system components can be difficult to formulate. In this paper, a systematic design methodology for an efficient IPT LED lighting system is proposed. The analysis, implementation, and verification are detailed.
