Ii-inductor yemodi evamileisetshenziswa kusekethe ye-CAN, nakuba ingeke ithuthukiswe ngokucacile ku-EMC. Onjiniyela abaningi bazongeza amasekethe azungeze i-CAN. I-chip ye-CAN inamandla we-anti-static kanye ne-transient voltage. Noma ngabei-inductor yemodi evamilekufanele ingezwe ku-CAN Circuit ibhekwa ngokuyinhloko kusukela kusici sokuhambisana kwe-electromagnetic

Kunamasekhethi amabili omthombo ovulekile ku-CAN, angashayela ibhasi ukuya ezingeni eliphezulu, kuyilapho izinga lokuhlehla litholwa ngokukhipha isithasiselo setheminali.

Ukudluliswa kokwehluka okungokwemvelo kwebhasi kunekhono elihle lokucindezela ukuphazamiseka kwemodi evamile, Ukuphazanyiswa kwemodi evamile ngaphandle kungaqedwa kahle ngokukhipha amasekhethi amabili omthombo ovulekile wangaphakathi. Kodwa-ke, amasekhethi amabili omthombo ovulekile awawona ama-symmetry afanelekile futhi akhuphuka ngokushesha, okuzoholela ezinkingeni zokuhambisana kwe-EMC electromagnetic.

Singabona ku-oscilloscope ukuthi i-waveform yebhasi isezingeni kakhulu, futhi ukuhlinzwa, ugesi omile, iqembu le-EFT transient pulse kanye nokungavikeleki okwenziwayo kujwayelekile. Kodwa-ke, lapho kwenziwa ukuhlolwa kokudlulisela, kuzobonisa okungavamile. Ibhasi elibukeka lijwayelekile empeleni lithumela ukuphazamiseka okwenziwe ngaphandle.

Kumjikelezo we-CAN, uma ufuna ukwenza ukuxhumana kwebhasi kuthembeke kakhulu futhi uxazulule inkinga ye-EMC yesixhumi esibonakalayo, ngaphezu kwe-CAN transceiver chip, enye indlela yokwengeza ama-peripherals ku-interface ye-CAN.I-inductor yemodi evamilekuyisinqumo esihle. Ama-transceiver amaningi e-CAN azokweqa umkhawulo wokuphazamiseka owenziwe.

I-inductor yemodi evamileinganciphisa ukuphazamiseka, kodwa ibhasi kanye ne-inductor yemodi evamile ingase ibangele izinkinga ze-resonance kanye ne-voltage yesikhashana. I-inductor yemodi evamile izoba ne-parasitic inductance, ukumelana nezinye izici ezizothinta ikhwalithi yesignali yebhasi, okuholela ekulimazeni kwesignali. I-inductor yemodi evamile ine-inductance enkulu. Uma isetshenziswa ku-interface ye-transceiver, ipulaki eshisayo nezinye izimo zokusebenza, iziphetho ezimbili ze-inductor yemodi evamile zikhiqiza i-voltage ephezulu yesikhashana, engalimaza i-transceiver ye-CAN. Ngakho-ke, i-resonance kanye ne-voltage yesikhashana ebangelwa yiyo kufanele kusacatshangelwa ekusetshenzisweni kwayo.

Uma unentshisekelo, sicela ukhululekeXhumana noMingDaukuze uthole imininingwane eyengeziwe.
