FCC认证中的9 kHz～30 MHz低频磁场辐射解决方案

9 kHz～30 MHz Low Frequency Magnetic Field Radiation Solution for FCC Certification

介绍FCC PART 18对工科医疗设备中感应类炊具的低频电磁场辐射要求,指出感应类家电产品在满足这一技术要求时面临的技术难点。对法规限值、测试方法和判定依据的深度理解有助于解决实际问题。文章给出了屏蔽电磁波、降低IH信号辐射频率、对IH 信号进行抖频处理等几种解决办法,以降低低频电磁场辐射。

All IH domestic appliances of the ISM equipment that import to USA market shall be met the FCC part 18 regulation.And it indicate the technical difficulty that can be fit for the standard in this paper.The deep understanding in limit line,test methods and the criterion can help to solve this problem.In this paper it provide shielding the electromagnetic wave,decreasing the IH signal radiation frequency and frequency jitter technology to reduce the low frequency electromagnetic radiation.
