Abstract : In the present era, electricity is one of the essential needs of human society. Transmission lines are used in conventional power system which is expensive and less efficient. Transmission line losses account for the major reduction in transmission efficiency due to long transmission lines spanning several kilometres. One best solution for this old-age problem is to have wireless power transmission (WPT). Not only in transmission, can any application module can be made compact and energy efficient using WPT concept. In WPT, AC voltage is rectified, converted to high-frequency AC, and transmitted using inductive power transfer or capacitive power transfer approach. Inductive power transfer system contains transmitter and receiver coils designed for high-frequency AC voltage. Therefore, the coils’ size is reduced and they can be made compact. In this paper, a WPT scheme is proposed for LED lighting which can be used in public information display system. The system is designed to drive 100 W LED display unit. Class-DE inverter is considered and series–parallel resonance is used in transmitter and receiver coil sides, respectively. The simulation results are presented. © 2019, Springer Nature Singapore Pte Ltd.
