American National Standard for Methods of Measurements of Radio-Frequency Emissions from Wireless Power Transfer Equipment

Abstract

Overview

The document provides an American national standard for measuring radio-frequency emissions from wireless power transfer equipment ranging from 9 kHz to 40 GHz. The guidelines prioritize coherence with other national and international standards. This standard aims to standardize measurement methods without defining specific emission limits.

Scope

• Includes detailed procedures for evaluating wireless power transfer equipment's compliance with electromagnetic compatibility requirements.
• Covers both radiated field strength and conducted disturbance measurements with references to other established standards.

Purpose

Defines the measurement methods for assessing compliance with radiated and power-line conducted emissions for various wireless power transfer devices. It spans devices that are prevalent or expected to be released soon as of the first publication of ANSI C63.30 in 2021, such as Qi, PMA, and other models.

Exclusions

Specific procedures for RF exposure compliance or tests for transmitter or receiver portions outside the primary wireless transmission frequencies are excluded, being covered by other standards.
