A novel Qi-standard compliant full-bridge wireless power charger for low power devices

Abstract

In this paper a Qi-standard compliant compact wireless power charger system, composed of a wireless power transmitter and a wireless power receiver, is presented. The developed system aims to be compliant with the latest revision of Wireless Power Consortium's directives and uses a full-bridge resonant inverter as the main power transmitter architecture. The wireless power transmitter and receiver have been designed with ultra low power and high efficiency electronics components thereby maximizing the overall power transfer efficiency.
