ANSI C63.30-2021 pdf download.Methods of Measurements of Radio-Frequency Emissions from Wireless Power Transfer Equipment.
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.
Keywords:ANSI C63.30,conducted emission testing,conducting ground plane,electric field measurement,intentional radiators,line impedance stabilization network,magnetic field measurement,radiated emission testing,unintentional radiators,wireless power transfer,wireless power transfer equipment.
This standard specifies procedures for verifying the electromagnetic compliance of wireless power transfer devices of various technologies,including but not limited to:small charging mat-type wireless power chargers (e.g.,for cell phone or laptop)，medium-size wireless charging devices (e.g.,for home appliances)，as well as large wireless power charging systems (e.g.,for automobile or industrial machinery)。
This first edition includes measurement procedures applicable to wireless power transfer devices that are or are soon to be introduced on the market at the time of publication of this standard.As new WPT technologies mature,they will be addressed in future revisions of this standard.
Measurement methods are included for radiated and alternating current (ac)mains power-line conducted emissions that can be generated by a variety of WPT devices,as described in 1.2.For correctly measuring such emissions,this standard prescribes a sequence of three procedures:frequency identification (for determining the EUT emission frequencies)，exploratory measurements (for determining the set of conditions under which the EUT generates the highest emission relative to the applicable limit)，and maximization (manipulation and operation of test instrumentation for determining the level of the highest emission from the EUT).These three processes are defined in 3.1.
Definitions are provided for terms and phrases contained in the text,in which the words do not represent obvious or common usage.Additional definitions are provided when multiple WPT organizations use different terms to describe the same component or subsystem of a WPT device.In most cases,measurement instrumentation and calibration requirements are only generally characterized in deference to standards dedicated to these subjects,which should be used in conjunction with this standard.The requirements for operation of test samples during measurements are presented for devices in general,as well as for specific types of devices that are frequently measured,with special attention given to application-level variations due to variables such as size,implementation,power level,and power transmission distance.Specific requirements for emission test data recording and reporting are also included.The main text is augmented by a series of annexes that provide other useful information or normative requirements.ANSI C63.30-2021 pdf download
