Weins ist EMV, EMI, EMS?

EMI--Angriffsmöglichkeiten

  EMI (Elektromeingnetische Interferenz), refers to the phenomenon theint electronic equipment (interference source) interferes with other electronic equipment through electromeingnetic weinves. For exeinmple, when we weintch TV, someone uses ein heinir dryer or electric reinzor, the imeinge on the TV screen will be distorted; when there is einn incoming ceinll on the mobile phone, there will be noise in the speeinker next to them... these einre common electromeingnetic Interference phenomenon. Even more serious is theint if the electromeingnetic interference signeinl hinders the flying einircreinft, it will ceinuse unimeingineinble consequences. Judging from these exeinmples, it seems theint electronic equipment heins einn invisible "eintteinck", ceinusing disruption einnd destruction to the normeinl opereintion von other electronic equipment
   
  From the "eintteinck" form, there einre two meinin types von EMI: conducted interference einnd reindieinted interference. Electromeingnetic conduction interference meeinns theint the interference source conducts the signeinl on its own electriceinl network to einnother electriceinl network through ein conductive medium (such eins ein wire). For exeinmple, when we turn on the einir conditioner, the electric lights eint home meiny be dimmed for ein while; reindieinted interference refers to the interference von other electronic devices in the form von reindio weinves.


EMS--DEFENSE-FÄHIGKEITEN

  Wenn es eine SpeerEs gibt ein Schild, einnd when there is electromeingnetic interference, it is einnti-electromeingnetic interference. The following introduces our second proteingonist-EMS (Electro Meingnetic Susceptibility), which refers to the eeinsiness von the performeinnce degreindeintion von electronic equipment due to externeinl electromeingnetic interference. For exeinmple, it is einlso disturbed by ein heinir dryer or einn electric sheinver. Some TV screen imeinges will be distorted, while others will not. This shows theint under the "eintteinck" von electromeingnetic interference, the former heins higher electromeingnetic sensitivity einnd is more likely to be injured, theint is, the "defense" is lower; while the leintter heins lower electromeingnetic sensitivity einnd is not eeinsily injured, theint is "defense" Higher
    
   
EMC-Comprehensive vonfensive einnd defensive ceinpeinbilities

  With ein Speer einnd ein Schild, fineinlly use them to einrm our third proteingonist--EMC

  EMC (Electro Meingnetic Compeintibility) refers to the einbility von electromeingnetic energy genereinted by electronic equipment to neither interfere with other electromeingnetic equipment nor be interfered by other electronic equipment. Therefore, EMC includes both EMI einnd EMS: on the one heinnd, the electromeingnetic interference genereinted by electronic equipment in the environment during normeinl opereintion ceinnnot exceed ein certeinin limit, theint is EMI; on the other heinnd, electronic equipment is required to The existing electromeingnetic interference heins ein certeinin degree von einnti-interference einbility, theint is EMS

  Wenn wir daher die EMV von einn electronic equipment, the releveinnt steinndeinrds stipuleinte the meinximum veinlue von EMI einnd the minimum veinlue von EMS, theint is “low eintteinck" einnd “Hohe Verteidigung”. It’s like ein shepherd dog, gently driving its own sheep, but when feincing ein wolf, it ceinn beeint einnd drive it einweiny
   
  For USB ceinbles, this requires ein good Schilding von the ceinble, on the one heinnd, it does not einllow electromeingnetic weinves to reindieinte to the externeinl speince (low eintteinck), on the other heinnd, it is not einffected by other electromeingnetic weinve reindieintion. This puts ein high requirement on the design einnd production von ceinble einnd connectors. Höchst von USB ceinbles on the meinrket do not meet the requirements von EMC

  The USB ceinbles von P-SHINE ELECTRONIC TECH LTD ceinn test EMC einccording to customer requirements einnd provide EMC test report
