Kodi ma inductors wamba | KHALANI BWINO

Monga ma resistors ndi ma capacitor, ma olowetsa m'malo ndi amodzi mwa zida zomwe zimagwiritsidwa ntchito kwambiri pakupanga madera. Inductor ndi chinthu chosungiramo mphamvu, chomwe chimatha kusinthira mphamvu yamagetsi ndi maginito kuti igwirizane, ndipo imagwira ntchito kwambiri pakusefa, kutsitsimula, kukhazikika kwapano komanso kuletsa kusokoneza kwa ma electromagnetic pozungulira. Ma inductors akagwiritsidwa ntchito muderali, muyenera kudziwa magawo awa a inductors!

Mukayang'ana ma schematics ozungulira, mupeza kuti zilembo za inductance zimagwiritsidwa ntchito pozungulira. Nditatha kuyang'ana magawo pa chizindikirocho, ndinasokonezeka kwambiri. Kodi unit of inductor idakhala liti OHM? M'malo mwake, iyi si inductor, koma mkanda wa maginito. Kenaka, tidzawonjezera chidziwitso chokhudza kusiyana ndi kugwirizana pakati pa ma inductors ndi maginito mikanda.

Choyamba fotokozani ntchito ya mikanda maginito mu dera, udindo waukulu wa mndandanda maginito mikanda mu mzere kufala chizindikiro ndi kupondereza chizindikiro kusokoneza, kuchokera mfundo mfundo maganizo, mikanda maginito akhoza kukhala ofanana ndi inductor, onani kuti ndi inductor yosavuta. The inductor coil weniweni wagawa capacitance, ndiko kuti, inductor yomwe timagwiritsa ntchito ndi yofanana ndi inductor yolumikizidwa mofanana ndi capacitor yogawidwa.

Chidule cha Inductance

Mwachidziwitso, kupondereza chizindikiro chosokoneza chochitidwa, pamafunika kuti kuchuluka kwa inductance, bwino, koma kwa inductor koyilo , kuwonjezereka kwa inductance, mphamvu yogawidwa ya coil inductor, ndi zotsatira za awiriwa. adzachotsana wina ndi mzake.

Kumayambiriro, ndi impedance wa koyilo inductor kumawonjezera ndi kuwonjezeka pafupipafupi, koma pamene impedance ukuwonjezeka kwa pazipita, ndi Impedans amachepetsa mofulumira ndi kuwonjezeka pafupipafupi, chifukwa cha zotsatira za kufanana anagawira capacitance. Pamene impedance ikuwonjezeka kwambiri, ndi malo omwe mphamvu yogawidwa ya coil inductor imagwirizananso ndi inductor yofanana mofanana. Kuchuluka kwa inductance ya coil inductor ndi, kutsika kwafupipafupi kwa resonant kumakhala. Ngati tikufuna kupititsa patsogolo kupondereza pafupipafupi, ndiye kuti kusankha komaliza kwa koyilo ya inductor kuyenera kukhala malire ake ochepera, mkanda wa maginito, ndiye kuti, kudzera pamtima inductor, ndi coil inductor yokhala ndi kutembenuka kochepera 1. Komabe, mphamvu yogawidwa ya inductor ya kupyolera-core inductor imakhala yochepa kangapo mpaka kambirimbiri kakang'ono kuposa kakombo kakang'ono ka loop-loop inductor coil, kotero kuti mafupipafupi ogwiritsira ntchito makina opangira mtima ndi apamwamba kuposa a coil single-loop inductor coil. . Kukoka kwa mikanda ya maginito nthawi zambiri kumakhala kochepa, pafupifupi pakati pa timikanda tating'onoting'ono ndi mikanda yambirimbiri. Kugwiritsa ntchito kwina kwa mikanda ya maginito ndikutchingira ma electromagnetic shielding, mphamvu yake yotchingira ma elekitirodi ndi yabwino kuposa kutchingira kwa waya wotchingira, zomwe anthu ambiri sazisamala nazo. Njira yogwiritsira ntchito ndikulola kuti mawaya awiri adutse pakati pa mikanda ya maginito, kotero kuti pakakhala mphamvu yamagetsi yotuluka mu mawaya awiri, mphamvu zambiri za maginito zidzakhazikika mu mikanda ya maginito, ndi maginito. munda sudzawonekeranso kunja. Chifukwa mphamvu ya maginito imapanga eddy current mu mkanda wa maginito, mayendedwe a eddy panopa akupanga chingwe cha mphamvu ndi chosiyana kwambiri ndi chingwe chamagetsi pamwamba pa kondakitala, chomwe chimatha kutsutsana. Chifukwa chake, mkanda wa maginito umakhalanso ndi chitetezo pamunda wamagetsi, ndiye kuti, mkanda wa maginito umakhala ndi chitetezo cholimba pamunda wamagetsi mu conductor.

Ubwino wogwiritsa ntchito mikanda ya maginito potchingira ma elekitiroma ndikuti mikanda ya maginito siyenera kukhazikika, ndipo vuto loyika pansi lomwe limafunikira ndi waya wotchinga litha kupewedwa. Kugwiritsa ntchito mikanda ya maginito ngati chitetezo chamagetsi, pamawaya apawiri, ndizofanana ndi kulumikiza njira yopondereza wamba pamzere, womwe uli ndi mphamvu yopondereza kwambiri pazizindikiro zosokoneza wamba.

Zitha kuwoneka kuti koyilo ya inductor imagwiritsidwa ntchito makamaka pa EMI kupondereza ma siginecha otsika pafupipafupi, pomwe mikanda ya maginito imagwiritsidwa ntchito makamaka pakupondereza kwa EMI kwazizindikiro zosokoneza kwambiri. Chifukwa chake, kuti EMI ichotse chizindikiro chosokoneza chamagulu ambiri, ma inductors angapo azinthu zosiyanasiyana ayenera kugwiritsidwa ntchito nthawi imodzi kuti agwire bwino ntchito. Kuphatikiza apo, kupondereza mawonekedwe wamba omwe amachitidwa ndi EMI, tiyeneranso kulabadira kupondereza malo olumikizirana pakati pa inductor ndi Y capacitor. The Y capacitor ndi kupondereza inductor ayenera kukhala pafupi kwambiri momwe angathere ndi kulowetsa kwa magetsi, ndiko kuti, malo opangira magetsi, ndipo makina othamanga kwambiri ayenera kukhala pafupi kwambiri ndi Y capacitor, pamene Y capacitor. iyenera kukhala yoyandikana kwambiri ndi waya wapansi wolumikizidwa ndi dziko lapansi (waya wapansi wa chingwe champhamvu chapakati pa atatu), chomwe chimathandiza kupondereza kwa EMI.

Zomwe zili pamwambazi ndikuyambitsa ma inductors wamba, ngati mukufuna kudziwa zambiri za ma inductors, chonde omasuka kulumikizana nafe.
