什么规则可以管理短距离无线感应耦合充电板或充电设备? FCC Part 15 Part 18KDB 680106

        有鉴于无线充电产品已在移动通讯设备中或车用设备及医疗上面有广大的应用层面,那在申请FCC美国认证时该注意哪些内容呢?


1.无线充电产品需取决于产品工作型态,WPT设备可以以两种不同的模式运行:充电和通信;


2.产品描述,包括线圈直径,匝数和电流;


3.操作的频率& 辐射功率 frequency of operation; radiated power;


4.射频暴露量评估;


以上内容均可参考 KDB 680106有完整说明;


以下就D01V03 (20180409) 改动内容加以说明;

 

1.Power transfer frequency is less than 1 MHz.
   工作频段相同未作变动.


2.Output power from each primary coil is less than or equal to 15 watts.
   功率从原5W提升至15W.


3.The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that are able to detect and allow coupling only between individual pairs of coils
   线圈功能说明未作变动


4.Client device is placed directly in contact with the transmitter.
   说明仅贴设备尤其小心医疗植入设备如肠胃镜设备


5.Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion).
   针对移动设备,之前有说明60~400cm^2 (取决于功率大,线圈设计就变小关系)


6.The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit.
   变动原测试距离10cm规定,改成为距离产品上方位置20cm 与产品前后左右15cm 规定.另外限制值从原本30% 修正成50%;
