Abstract

American National Standard for Methods of Measurements of Radio-Frequency Emissions from Wireless Power Transfer Equipment "American National Standard for Methods of Measurements of Radio-Frequency Emissions from Wireless Power Transfer Equipment," in ANSI C63.30-2021 , vol., no., pp.1-253, 15 July 2021, doi: 10.1109/IEEESTD.2021.9491984. Abstract U.S. consensus standard methods, instrumentation, and facilities for measurement of radio-frequency (RF) emissions and signals emitted from wireless power transfer equipment in the frequency range from 9 kHz to 40 GHz are specified. This standard does not include generic nor product-specific emission limits. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes. Scope This standard includes procedures for evaluating the compliance of wireless power transfer (WPT) equipment with applicable electromagnetic compatibility (EMC) requirements. Test procedures for radiated field strength and conducted disturbance measurements are included, with reference to established standards, where applicable. WPT RF exposure compliance procedures are not included. This document covers measurement methodologies but is not intended to specify regulatory limits. This standard does not consider test methods for the transmitter or receiver portion of any radio apparatus subcomponents that might be included in the equipment under test (EUT), other than those operating at the WPT frequency (or frequencies). These non-WPT radio subcomponents, which can be related or not to the WPT function of the EUT, are covered by other standards (e.g., ANSI C63.10 [B1] and ANSI C63.26 [B2]). Purpose This standard specifies the methods of measurement to be used for evaluating compliance with the applicable radiated and ac mains power-line conducted emissions requirements for WPT devices that are either already in wide use or soon to be introduced on the market, at the time of publishing this first edition of ANSI C63.30 (such as Qi, PMA, A4WP2, and SAE3 J2954 [B26]compliant models

Main findings

This American National Standard specifies consensus methods, instrumentation, and facilities for measuring RF emissions/signals from wireless power transfer equipment over 9 kHz to 40 GHz, including radiated field strength and conducted disturbance measurements for EMC compliance evaluation. It does not specify generic or product-specific emission limits and does not include WPT RF exposure compliance procedures.

Outcomes measured

Measurement methods for RF emissions/signals from wireless power transfer equipment
Procedures for radiated field strength measurements
Procedures for conducted disturbance (ac mains power-line) measurements
Procedures for evaluating compliance with EMC requirements (measurement methodologies; not emission limits)

Limitations

No emission limits are provided (methods only).
WPT RF exposure compliance procedures are explicitly not included.
Does not cover test methods for non-WPT radio subcomponents (other than those operating at the WPT frequency/frequencies).
