Nekuvandudza tekinoroji yekusefa tekinoroji, tekinoroji yekusefa inoshanda zvakanyanya mukudzvanya kukanganiswa kwemagetsi, kunyanya kune EMI chiratidzo chekuchinja magetsi, iyo inogona kuita basa rakanaka mukukanganisa conduction uye kukanganisa mwaranzi.Differential mode interference signals uye common mode interference signals inogona kumiririra ese conduction interference signals pane magetsi.
Iyo yekutanga inonyanya kureva chiratidzo chekukanganisa chinofambiswa pakati pewaya mbiri, inova yesymmetry kukanganiswa uye inoratidzwa neakaderera frequency, kudiki kupindira amplitude uye kudiki kunogadzirwa kwemagetsi kukanganiswa.Iyo yekupedzisira inonyanya kureva kutapurirana kwezviratidzo zvekuvhiringidza pakati pewaya neyakavharirwa (nyika), inova yeasymmetric kupindira, uye inoratidzwa nehupamhi hwepamusoro, yakakura kupindira amplitude uye yakakura inogadzirwa electromagnetic kupindira.
Zvichienderana neongororo iri pamusoro, chiratidzo cheEMI chinogona kudzorwa pazasi peyero yekugumira inotsanangurwa neEMI zviyero kuzadzisa chinangwa chekudzikisa kukanganiswa kwekuita.Pamusoro pekudzvinyirira kunoshanda kwekukanganisa masosi, EMI mafirita akaiswa mune yekupinza uye kubuda maseketi eiyo switching magetsi inzira zvakare yakakosha yekudzvanya kukanganiswa kwemagetsi.Iyo yakajairika yekushanda frequency yemidziyo yemagetsi kazhinji iri pakati pe10MHz uye 50MHz.Mazhinji eEMC chiyero cheiyo yakaderera conduction yekupindira level muganho wegumi MHZ, yeakakwira frequency switch simba rekupa EMI chiratidzo, chero sarudzo yetiweki chimiro chiri nyore EMI sefa kana kudzoreredza EMI sefa yedunhu iri nyore, kwete chete inogona kubudirira. chinangwa chekudzikisa kusimba kwepamusoro-frequency common-mode ikozvino, zvakare inogona kugutsa kusefa kweEMC mirau.
Nheyo yekugadzira yekusefa yemagetsi yekubatanidza yakavakirwa pane iri pamusoro musimboti.Pane dambudziko rekupindirana pakati pemidziyo yemagetsi nemagetsi uye pakati pezvakasiyana midziyo yemagetsi, uye sefa yemagetsi yekubatanidza isarudzo yakanaka yekudzikisa kupindira.Sezvo pini yega yega yesefa yekubatanidza ine yakaderera-pass sefa, pini yega yega inogona kunyatso kusefa yakajairwa modhi ikozvino.Uye zvakare, iyo sefa yemagetsi yekubatanidza zvakare ine yakanaka kuenderana, saizi yayo yekutarisa uye saizi yechimiro uye yakajairwa magetsi yekubatanidza zvakafanana, saka, ivo vanogona kutsiviwa zvakananga.
Mukuwedzera, kushandiswa kwesefa yemagetsi yekubatanidza kunewo hupfumi hwakanaka, iyo inonyanya nokuti iyo sefa yemagetsi yekubatanidza inongoda kuiswa muchiteshi chebhokisi rakadzivirirwa.Mushure mokunge yabvisa kupindira ikozvino mutambo, kondakita haachanzwa chiratidzo chekupindira, saka ine kushanda kwakasimba kupfuura tambo yakavharidzirwa.Iyo sefa yemagetsi yekubatanidza haina zvakakwirira zvinodikanwa zvekupedzisira kubatana kwetambo, saka haidi kushandisa yakakwirira-yepamusoro shield cable zvachose, iyo inowedzera kuratidza hupfumi hwayo huri nani.
