He aha ka EMI Electromagnetic Interference
Kāpae
ʻO ka Electromagnetic Interference (EMI) i wehewehe nui ʻia e like me ka hoʻopili uila a i ʻole ka hoʻopili ʻana i nā mea uila e hoʻohaʻahaʻa a hoʻopilikia paha i ka hōʻailona hōʻailona a i ʻole nā ​​ʻāpana a me nā hana o nā mea uila.ʻO ka interference electromagnetic, me ka interference radio frequency, e hāʻule maʻamau i ʻelua mau ʻāpana ākea.ʻO nā hoʻokuʻu ʻana i ka narrowband maʻamau i hana ʻia e ke kanaka a hoʻopaʻa ʻia i kahi wahi liʻiliʻi o ka lekiō.ʻO ka Hum mai nā laina mana he kumu hoʻohālike maikaʻi o ka hoʻokuʻu ʻana i ka narrowband.Hoʻomau a kaʻawale paha lākou.Hiki ke hana ʻia ka radiation broadband i ke kanaka a i ʻole kūlohelohe.Hoʻopili lākou i nā ʻāpana ākea o ka spectrum electromagnetic.ʻO ia kāna mau hanana hoʻokahi wale nō, ʻokoʻa, a i ʻole mau.ʻO nā mea a pau mai ka uila a hiki i nā lolouila e hoʻopuka i ka radiation broadband.
Puna EMI
ʻO ka hoʻopili electromagnetic e pili ana i nā kānana EMI hiki ke hele mai ma nā ʻano like ʻole.I loko o nā lako uila, hiki ke hoʻopilikia ʻia ma muli o ka impedance, hoʻohuli i nā au i nā uea pili.Hiki ke hoʻololi ʻia e nā hoʻololi uila i nā conductors.Hoʻokumu ʻia ʻo EMI ma waho e ka ikehu ākea e like me nā lapalapa o ka lā, ka mana a i ʻole nā ​​laina kelepona, nā mea hana, a me nā laina mana.Hoʻokumu ʻia ka hapa nui o ka EMI ma nā laina mana a lawe ʻia i nā mea hana.ʻO nā kānana EMI nā mea hana a i ʻole nā ​​modula kūloko i hoʻolālā ʻia e hōʻemi a hoʻopau paha i kēia mau ʻano keakea.
kānana EMI
Me ka ʻole o ka ʻimi ʻana i ka ʻepekema koʻikoʻi, ʻo ka hapa nui o ka electromagnetic interference aia i ka laulā kiʻekiʻe.ʻO ia ke ʻano o ke ana ʻana i kahi hōʻailona e like me ka hawewe sine, kokoke loa nā manawa.Loaʻa i nā kānana EMI ʻelua ʻāpana, kahi capacitor a me kahi inductor, e hana pū ana e kāohi i kēia mau hōʻailona.Hoʻopau nā Capacitors i nā au pololei a hele i nā ʻano ʻē aʻe kahi e lawe ʻia ai ka nui o ka interference electromagnetic i loko o ka hāmeʻa.ʻO ka inductor kahi electromagnet liʻiliʻi e mālama i ka ikehu i loko o kahi māla magnetic i ka wā e hele ai ka manawa i loko, e hōʻemi ana i ka volta holoʻokoʻa.ʻO nā capacitor i hoʻohana ʻia i nā kānana EMI, i kapa ʻia ʻo shunt capacitors, e mālama i nā kaha alapine kiʻekiʻe i loko o kahi mamao mai kahi kaapuni a i ʻole nā ​​​​mea.Hāʻawi ka capacitor shunt i kahi alapine kiʻekiʻe / hoʻopilikia i kahi inductor i hoʻokomo ʻia i ka moʻo.Ke hele nei ka manawa i kēlā me kēia inductor, hāʻule ka ikaika holoʻokoʻa a i ʻole ka volta.ʻO ke kūpono, hoʻemi nā inductors i ka interference i ka ʻole.Kapa ʻia kēia he pōkole i ka honua.Hoʻohana ʻia nā kānana EMI i nā ʻano hana like ʻole.Loaʻa iā lākou i loko o nā mea hana hale hana, nā mea lekiō, nā kamepiula, nā mea lapaʻau, a me nā lako kaua.
E aʻo e pili ana i kā mākou EMI/EMC kānana hoʻonā

Hoʻopau nā Capacitors i nā au pololei a hele i nā ʻano ʻē aʻe kahi e lawe ʻia ai ka nui o ka interference electromagnetic i loko o ka hāmeʻa.ʻO ka inductor kahi mea uila liʻiliʻi liʻiliʻi e mālama i ka ikehu i loko o kahi māla magnetic ke hele ʻia ke au i loko o ia mea, e hoʻemi ana i ka hāʻule holoʻokoʻa.ʻO nā capacitor i hoʻohana ʻia i nā kānana EMI, i kapa ʻia ʻo shunt capacitors, e mālama i nā kaha alapine kiʻekiʻe i loko o kahi mamao mai kahi kaapuni a i ʻole nā ​​​​mea.Hāʻawi ka capacitor shunt i kahi alapine kiʻekiʻe / hoʻopilikia i kahi inductor i hoʻokomo ʻia i ka moʻo.Ke hele nei ka manawa i kēlā me kēia inductor, hāʻule ka ikaika holoʻokoʻa a i ʻole ka volta.ʻO ke kūpono, hoʻemi nā inductors i ka interference i ka ʻole.Kapa ʻia kēia he pōkole i ka honua.Hoʻohana ʻia nā kānana EMI i nā ʻano hana like ʻole.
