Ii-inductor yendlela eqhelekileyoisetyenziswe kwisekethe ye-CAN, nangona ingenakuphuculwa ngokucacileyo kwi-EMC. Iinjineli ezininzi ziya kongeza iisekethe ezijikeleze i-CAN. Itshiphu ye-CAN ine-anti-static kunye namandla ombane wexeshana. Nokuba ngabai-inductor yendlela eqhelekileyokufuneka ifakwe kwi-CAN Circuit iqwalaselwa ikakhulu kwinkalo yokuhambelana kwe-electromagnetic

Kukho iisekethe ezimbini zomthombo ovulekileyo kwi-CAN, ezinokuqhuba ibhasi ukuya kwinqanaba eliphakamileyo, ngelixa inqanaba lokuphindaphinda liphunyezwa ngokukhutshwa kwe-terminal resistor.

Ukuhanjiswa okungafaniyo kwebhasi kunamandla okuthintela ukuphazamiseka kwendlela eqhelekileyo, Ukuphazamiseka kwemowudi eqhelekileyo ngaphandle kunokupheliswa kakuhle ngokukhupha iisekethe ezimbini zangaphakathi ezivulelekileyo. Nangona kunjalo, iisekethe ezimbini zomthombo ovulekileyo azikho i-symmetry efanelekileyo kwaye zinyuka ngokukhawuleza, nto leyo eya kukhokelela kwiingxaki zokuhambelana kombane we-EMC.

Sinokubona kwi-oscilloscope ukuba i-wave wave yebhasi isemgangathweni kakhulu, kunye nokunyuka, umbane ongatshintshiyo, iqela le-EFT elidlulayo le-pulse kunye ne-immunity eqhutywe yinto eqhelekileyo. Nangona kunjalo, xa kuqhutywa uvavanyo losulelo, kuya kubonisa ukungaqhelekanga. Ibhasi ekhangeleka njengesiqhelo ithumela uphazamiseko oluqhutywayo ngaphandle.

Kwisiphaluka se-CAN, ukuba ufuna ukwenza unxibelelwano lwebhasi luthembeke ngakumbi kwaye usombulule ingxaki ye-EMC ye-interface, ngaphezu kwe-CAN transceiver chip, enye indlela yokongeza i-peripherals kwi-interface ye-CAN.Inductor yemowudi eqhelekileyolukhetho olulungileyo. Uninzi lwee-CAN transceivers ziya kugqitha kumda wokuphazamiseka owenziweyo.

Inductor yemowudi eqhelekileyoinokunciphisa ukuphazamiseka, kodwa ibhasi kunye ne-inductor yemowudi eqhelekileyo inokubangela i-resonance kunye neengxaki zombane ezidlulayo. I-inductor yemodi eqhelekileyo iya kuba ne-parasitic inductance, ukuchasana kunye nezinye izinto eziza kuchaphazela umgangatho wesignali yebhasi, ekhokelela ekuthotyweni komqondiso. I-inductor yendlela eqhelekileyo ine-inductance enkulu. Xa isetyenziswe kwi-interface ye-transceiver, iplagi eshushu kunye nezinye iimeko zokusebenza, iziphelo ezimbini ze-inductor yemodi eqhelekileyo zivelisa i-voltage ephezulu edlulayo, enokonakalisa i-CAN transceiver. Ke ngoko, i-resonance kunye ne-voltage edlulayo ebangelwa yiyo kusafuneka iqwalaselwe kwisicelo.
