标准范围

IEC 62680-1-2:2022规范定义了涵盖USB系统所有元件的电源传输系统，包括:主机、设备、集线器、充电器和电缆组件。本规范描述了管理高达100W的USB电源传输所需的体系结构、协议、电源行为、连接器和布线。本规范旨在完全兼容并扩展现有USB基础设施。本规范旨在使系统原始设备制造商、电源和外围设备开发商在不丧失向后兼容性的情况下，为产品的多功能性和市场差异化提供足够的灵活性。第六版取消并取代了2021出版的第五版，构成技术修订版。增加了包括可调电压电源（AVS）在内的扩展功率范围（EPR）。本文件是USB-IF出版物通用串行总线电源交付规范第3版。1，1.1版。

IEC 62680-1-2:2022 specification defines a power delivery system covering all elements of a USB system including: Hosts, Devices, Hubs, Chargers and cable assemblies. This specification describes the architecture, protocols, power supply behavior, connectors and cabling necessary for managing power delivery over USB at up to 100W. This specification is intended to be fully compatible and extend the existing USB infrastructure. It is intended that this specification will allow system OEMs, power supply and peripheral developers adequate flexibility for product versatility and market differentiation without losing backwards compatibility. This sixt edition cancels and replaces the fifth edition published in 2021 and constitutes a technical revision. Extended Power Range (EPR) including Adjustable Voltage Supply (AVS) has been added. This docuemnt is the USB-IF publication Universal Serial Bus Power Delivery Specification Revision 3.1, Version 1.1.
