Abstract

The Alliance for Wireless Power (A4WP) Version 1.0 Baseline System Specification (BSS) is an interoperability specification for loosely-coupled (LC) wireless power transfer (WPT) systems that meet next-generation user experience and industrial design requirements as part of the vision of Ubiquitous Power for portable, hand-held, consumer electronic devices. This survey of the A4WP Version 1.0 BSS reviews an LC WPT reference model, power transmitting and power receiving unit device classification, power system interfaces and key parameters, the power control specification, the signaling specification, and the framework for certification and acceptance testing based on reference power transmitting and power receiving resonators. The selection of ISM band (6.78MHz) as the WPT operating frequency and ISM band (2.4GHz) for WPT management protocol via BluetoothLE is discussed.
