摘要：提到的EMI所有的电子系统，其中包括开关稳压器发出的有害电磁辐射。采用扩频脉冲宽度调制控制计划（SSPWM）增强的EMI抑制。驾驶与伪随机噪声（PN）的外部时钟输入引脚的MAX1703DC-DC转换稳压器提供了降低EMI的扩频时钟。遍布广泛的干扰频率降低EMI的功率密度，否则集中在一个单一的时钟频率。Maxim>AppNotes>CIRCUITPROTECTIONPOWER-SUPPLYCIRCUITSKeywords:EMI,radiation,suppression,SSPWM,spread-spectrumpulse-widthmodulation,electromagneticMay28,2002interference,MAX1703,dc-dcconverter,dcdcconverters,convertorsAPPLICATIONNOTE1077DC-to-DCConverterCombatsEMIAbstract:UnwantedelectromagneticradiationreferredtoasEMIisemittedbyallelectronicsystems,includingswitchingregulators.Adoptingspread-spectrumpulse-widthmodulation(SSPWM)asacontrolschemeenhancesthesuppressionofEMI.DrivingtheexternalclockinputpinoftheMAX1703DC-DCconverterwithapseudo-randomnoise(PN)providestheregulatorwithaspreadspectrumclockthatreducesEMI.SpreadingtheinterferencefrequenciesoverawiderangelowerstheEMIpowerd……

摘要：美国联邦通信委员会（FCC）的政府机构，规范无线电频率（RF）在美国的排放量，在1975年颁布称为FCC第15部分的新法规。这些都没有在控制设备，如广播和电视发射机，或飞机导航和紧急信标，故意辐射高功率射频能量。相反，这些法规旨在控制设备，确实不是故意的辐射射频能量，如电视，汽车，低功耗，对讲机和电子遥控器，如无管制射频散热器。在20世纪80年代和20世纪90年代，电子设备，手机增殖微波炉。这些设备之间的交叉干扰就成了一个问题。传统的方法来解决辐射问题，包括屏蔽，精心的电路板布局，以及过滤，以减少意外的辐射。作为电子产品变得越来越小，另一种技术，扩频通信应用借来使用。本文给出了扩频的背景和历史，并介绍如何使用它作为今天的技术，以减少在消费电子设备的辐射。Maxim>AppNotes>CommunicationsCircuitsWireless,RF,andCableKeywords:EMI,spreadspectrum,EMIreduction,EMIcontrol,dither,DS1086,radiationcontrol,radiationMay29,2003reduction,FCCPart68APPLICATIONNOTE1995UsingSpreadSpectrumOscillatorstoReduceRadiatedEmissionsinConsumerProductsAbstract:In1975theFederalCommunicationsCommission(FCC),thegovernmentagencythatregulatesradiofrequency(RF)emissionsintheUnitedStates,enactednewregulationscalledFCCPart15.ThesewerenotdirectedatcontrollingequipmentsuchasradioandTVtransmitters,oraircraft-navigationandemergencybeaconsthatdeliberatelyradiatehigh-powerRFenergy.Instead,theseregulationssoughttocontrolequipmentthatdidnotdeliberatelyradiateRFenergysuc……
