Thecommon mode inductorinoshandiswa mudunhu reCAN, kunyangwe isingakwanise kuvandudzwa zvakajeka muEMC. Mainjiniya mazhinji anozowedzera maseketi akatenderedza CAN. CAN chip ine anti-static uye yenguva pfupi voltage kugona. Kanacommon mode inductorinofanirwa kuwedzerwa kuCAN Circuit inonyanya kutariswa kubva pachikamu chekuenderana kwemagetsi
Kune maviri akavhurika sosi maseketi muCAN, ayo anogona kutyaira bhazi kusvika padanho repamusoro, nepo recessive level inoitwa kuburikidza nekuburitswa kweiyo terminal resistor.
The inherent differential transmission yebhazi ine simba rakanaka rekudzvanyirira common-mode kupindira, Iyo common mode kupindira kubva kunze inogona kubviswa zvakanaka nekubvisa maviri emukati akavhurika sosi maseketi. Nekudaro, iwo maviri akavhurika sosi maseketi haana kunaka symmetry uye ari kusimuka nekukurumidza, izvo zvinotungamira kune EMC electromagnetic kuenderana matambudziko.
Isu tinogona kuona kubva kune oscilloscope kuti iyo bhazi waveform yakanyanya mwero, uye kuvhiya, static magetsi, EFT yenguva pfupi pulse boka uye inoitiswa kusadzivirirwa kwakajairika. Nekudaro, kana uchiitisa bvunzo yekutapurirana, inoratidza kusakwana. Bhazi rinotaridzika zvakanaka rinotumira kukanganisa kwaitwa kunze.
Mudunhu reCAN, kana iwe uchida kuita kuti kutaurirana kwebhazi kuve kwakavimbika uye kugadzirisa EMC dambudziko reiyo interface, kuwedzera kune CAN transceiver chip, imwe nzira ndeyekuwedzera peripherals kuCAN interface.Common mode inductorisarudzo yakanaka. Mazhinji CAN transceivers anodarika iyo yakaitwa yekuvhiringidza muganho.
Common mode inductorinogona kuderedza mhirizhonga, asi bhazi pamwe neyakajairwa modhi inductor inogona kukonzera resonance uye yenguva pfupi voltage matambudziko. Common mode inductor ichave neparasitic inductance, kuramba uye zvimwe zvinhu zvinokanganisa kunaka kwechiratidzo chebhazi, zvichitungamira mukuderedzwa kwechiratidzo. Iyo yakajairika-modhi inductor ine yakakura inductance. Kana ichinge yaiswa kune iyo transceiver interface, inopisa plug uye mamwe mamiriro ekushanda, iyo miviri migumo ye common-mode inductor inoburitsa transient high voltage, iyo inogona kukuvadza CAN transceiver. Naizvozvo, iyo resonance uye yenguva pfupi voltage yakakonzerwa nayo inofanirwa kuramba ichitariswa mukushandisa.
Kana iwe uchifarira, ndapota inzwa wakasunungukataura naMingDakuti uwane mamwe mashoko.
