29、RNATIONAL ELECTROTECHNICAL COMMISSION _ ACTIVITIES AND CONSIDERATIONS RELATED TO WIRELESS POWER TRANSFER (WPT) FOR AUDIO, VIDEO AND MULTIMEDIA SYSTEMS AND EQUIPMENT FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
30、 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Sp
31、ecifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. Inter
32、national, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The fo
33、rmal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations
34、for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
35、 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication sh
36、all be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent cert
37、ification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal in
38、jury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references
39、 cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for ident
40、ifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an Internati
41、onal Standard, for example “state of the art“. IEC 62869, which is a technical report, has been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this technical report is based on the following documents: Enquiry draft Report on voting 100/2134/D
42、TR 100/2166/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. TR 62869 IEC:2013(E) 7 The committee has decided that the c
43、ontents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual
44、 version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a co
45、lour printer. 8 TR 62869 IEC:2013(E) INTRODUCTION IEC TC 100 established a Stage 0 project on wireless power transfer (WPT) to develop a technical report on WPT technical standardization in relation to audio, video and multimedia systems and equipment. A survey was developed to investigate the globa
46、l positioning of the technology and its uptake. Twelve National Committees provided responses. Four National Committees (China, Japan, Korea, USA) provided responses to all questions. The key research undertaken and information gathered from the survey responses included: a) terms and definitions us
47、ed for WPT by IEC TC 100 members; b) regulations, national laws, public policies and industry practices related to WPT; c) status of activities and discussions in various organizations relating to regulatory activities, standards projects, and market research; d) potential topics to be addressed in
48、IEC TC 100 TR: and e) potential role for IEC TC 100 in the domain of WPT technical standards development. This Technical Report combines survey results with Stage 0 project expert group contributions and extensive public information to develop and present a holistic understanding of WPT and, in so d
49、oing, respond to the Stage 0 TR objectives. This understanding is developed through a progression of four interrelated topics. Clause 4 considers the overall WPT market, including use cases, public benefit, academic research activities, and an overview of WPT products and services. Clause 5 discusses leading commercial WPT technical approaches and briefly surveys additional WPT technologies by reviewin
