Wireless power transmission for multiple devices

Abstract

Wireless power transmission concept has being revolutionary emerging against the conventional charging methods of consumer electronics. In this paper, we present the concept of wireless power transmission for multiple devices. Simultaneous wireless power transmission via resonant inductive coupling is experimentally demonstrated for a system with single transmitter and two receivers. Resonance between source and load is achieved with lumped capacitors connecting the coils. The circuit design is developed to describe a system with a single receiver, and extended to describe the system with two receivers.
