Rezence – Wireless Charging Standard based on Magnetic Resonance

Abstract: With the advancement in Wireless Technology, Wireless Power Transfer (WPT) is one aspect of the field which has garnered immense recognition over the past couple of years. Different Wireless Charging Standards are based on different principles, namely Magnetic Induction and Magnetic Resonance. Rezence is an interface standard developed by the Alliance for Wireless Power (A4WP) which is based on the principle of Magnetic Resonance. Rezence purports itself to be the �next-generation� of wireless charging technology. Rezence systems are loosely-Coupled (LC) WPT systems. This enables Rezence systems to charge multiple devices of diverse sizes and power requirements. Owing to this, LC WPT systems are finding a way into the day-to-day mainstream application of charging portable consumer electronic devices. Thus, by means of this paper, I endeavour to illustrate the working of Rezence and its advantages over other WPT systems.
