DESIGN OF A CURRENT-SOURCE-OUTPUT INDUCTIVEPOWER TRANSFER LED LIGHTING SYSTEM
Abstract
Inductive power transfer (IPT) light-emitting diode(LED) lighting systems have many advantages in commercial,industrial, and domestic applictions. Due to the large leakage inductance, primary and secondary capacitor compensationsare necessary to improve the power transfer capability. To offera direct current source output for LED driving, topology with series–series (SS) compensation is chosen and analyzed in thispaper. Using a properly designed operating frequency, the SS compensation can be the best topology for the voltagesource-input and current-source-output applications. To design an efficient IPT system, the loosely coupled transformer isthe key component whose design and interaction with othersystem components can be difficult to formulate. In this paper, a systematic design methodology for an efficient IPT LEDlighting system is proposed. The analysis, implementation, and verification are detailed.
