Inductors Inotsanangurwa: Mhando, Mabasa & Chaiyo-Nyika Inoshandiswa
Kunzwisisa Inductors: The Basics
Chii chinonzi Inductor?
An inductor chinhu chisingaiti chemagetsi chinochengetedza simba mundima yemagineti kana ikozvino ichifamba mairi. Muchidimbu, ingori kumonereka kwewaya, inogona kuputirwa nepakati pemhepo, simbi, kana chero chaunoda. Iyo yakakosha pfuma yeinductor ndiyo inductance yayo, inotsanangurwa seyero yevoltage kune chiyero chekuchinja kwezvino. Ichi chivakwa chinobatsira nenzira yakakosha kune inductors kushandiswa ne capacitors kugadzira mafirita uye inductors ari kushandiswa mune akasiyana mamwe maseketi kuchengetedza simba, senge mune magetsi. Kuita kwema inductors kune hukama zvakanyanya nekuvakwa kwayo kwemuviri, nhamba yekutendeuka mucoil, uye rudzi rwezvinhu zvakatenderedza musimboti.
Mhando dzeInductors
Kune akawanda marudzi emainductors, imwe neimwe inokodzera imwe mhando yekushandisa kana application. Mhando dzakajairwa dzakagadziriswa inductors, akasiyana inductors, toroidal inductors, uye air core inductors. Fixed inductors vane predetermined inductance, nepo variable inductors inogona kugadziriswa kuhuwandu hwekuita. Donut-shaped toroidal inductors vane mashandiro akanaka uye yakaderera EMI. Air core inductors haina musimboti, uye ine hurombo inductance, asi hapana yakakosha kurasikirwa. Sarudzo pamhando dzekushandisa yakavakirwa pane zvinodiwa zveiyo chaiyo application (yepamusoro-gomo kana kuburikidza-gomba), ingani inductance inodiwa, ikozvino kutakura kugona uye kuita pane frequency.
| Type | Core Material | Application |
| Fixed | Iron, Ferrite | Magetsi, Masefa |
| Variable | Air, Ferrite | Tuning Circuits |
| Toroidal | Ferrite, Iron Powder | High-efficiency Circuits |
| Multilayer | Ceramic, Ferrite | Compact RF uye dhijitari maseketi |
Core Materials uye Mabatiro Azvo
Iyo yakakosha mhepo yeinductor ndiyo kiyi yekuita kwayo. Iyo yakakosha zvinhu inogona kunge iri mhepo kana akasiyana marudzi esimbi alloys uye ferrites. Air core inductors vane mashoma inductance hunhu, zvisinei ivo havatarise kurasikirwa kwepakati uye saturation pama frequency akakwira saka akanyatsokodzera redhiyo frequency application. Iron cores inopa iyo yakakwirira inductance kukosha uye inoshandiswa muhuwandu hwemagetsi emagetsi. Nekuda kwekuve magineti ceramics, ferrite ine yakanaka kuwirirana pakati pepermeability uye kurasikirwa pane yakakwirira frequency uye saka yakakodzera kune Broadband uye highfrequency application. Iko kusarudzwa kwezvinhu zvakakosha kwakakosha nekuti ine chekuita nekusada kweinductor uye zvakare inokanganisa kushanda kweinductor, frequency remhinduro, uye simba-kubata masimba.
Mashandiro Anoita Inductors
Iyo Fizikisi Kuseri kweInductor
Pakati pebasa reinductor ndiyo musimboti we electromagnetic induction, yakawanikwa naMichael Faraday. Kana waya inotakura magetsi, inogadzira magnetic field. Simba reiyi magineti rakanangana neazvino rinopfuura nepawaya uye rinogona kuwedzerwa nekukochekera waya kugadzira inductor. Izvo zvinhu zviri pakati pewaya zvinewo kukanganisa kukuru kune magineti. Ferromagnetic zvinhu zvakaita sesimbi zvinogona kubvumira kuwedzera magineti simba, uye nekudaro, kune inonyatso shanda inductor. Inductor ine imwe yezvivakwa zvayo kuti ikwanise kuunganidza simba reiyo magnetic field kana ikozvino iri kusimuka, uye idzorere iyo kana ikozvino inodonha.
Inductor mune DC Circuit
MaInductors anoitawo zvimwe zvinoshamisa zvinhu kana akaiswa muDC wedunhu. Pakutanga kana DC voltage yaiswa, ichive reactive (L), iyo inductor inoramba shanduko mune yazvino uye inobvumira ikozvino kuyerera kuburikidza nekunonoka kudiki. Izvi zvakafanana neinertia, sezvo inductor inoramba kukurumidza kwekuchinja kwezvino kuyerera kuburikidza nayo. Kamwe iyo magineti yagara, iyo inductor inova pfupi dunhu uye iyo DC ikozvino inogona kuyerera ichipinda pasina chero kupikiswa (ichifunga kuti hapana kupikisa chaiko muwaya). Ichi chimiro chisina kujairika chinoratidza basa reinductor mukusefa nekudzikamisa dunhu nekudzima shanduko dzinongoerekana dzaitika.
Inductor mune AC Circuit
Inductor ine hunhu hune simba mu AC sezvo iripo muinductor inoramba ichichinja nekuchinja mafambiro ezvino mu AC Circuits. Izvi zvinokonzeresa kukwira bhasikoro kwemunda, kuvaka nekudonha, uye kugadzira voltage inopesana neyazvino, inonzi back EMF (Electromotive Force). Uku kushorwa kwekuchinja mune ikozvino kunoyerwa neiyo inductance reactance, inova frequency inotsamira. Iyo yakakwira frequency, yakakura iyo reactance, kuitira kuti inductors ishande semafirita ekukanganisa kwepamusoro-frequency. Hunhu uhu hwakakosha kune maapplication akaita seredhiyo tuning umo ma frequency chaiwo anotorwa kubva kune yakakura spectrum.
| Frequency (Hz) | Reactance (Ohms) |
| 100 | 6.28 |
| 1,000 | 62.8 |
| 10,000 | 628 |
Inoshanda Zvishandiso zveInductor
Inductors muMazuva ese Electronics
MaInductors anogona kunge asiri magamba eindasitiri yemagetsi ayo anopikisa, capacitors uye semiconductors, asi kana iwe uchida imwe kuti utore mudziyo uye uchimhanya mushure mekuputika kweinductor wayo, iwe uchafara kuti wadzidza chimwe chinhu chidiki pamusoro pavo. Iwo ekupedzisira haangoite basa rakakosha nekudzikisira kwekukanganisa kwemagetsi kuti ive nechokwadi chekushanda kwakatsetseka kwemidziyo yedu nemidziyo pasina kukanganiswa kubva kune ruzha rwekunze, asi zvakakoshawo mumaseketi emagetsi ekupa. Semuenzaniso, mumasekete emagetsi akaoma anowanikwa mumafoni efoni, inductors anoshanda pamwe nemacapacitor uye zvimwe zvikamu kugadzira buck kana boost converters, izvo zvakakosha pakugadzirisa zvakanaka voltage kune izvo zvinodiwa zvezvikamu zvakasiyana zvechishandiso. Izvi zvinoita kuti simba rishandiswe nemazvo sezvinobvira kwete pakuita chete asiwo kuwedzera hupenyu hwebhatiri.
Uye zvakare, inductors anoshandiswa mukusefa maapplication seanowanikwa muodhiyo uye vhidhiyo michina yemagetsi, vatauri, maikorofoni, uye T.V's. Kana ichibatanidzwa muLC (inductor-capacitor) sefa yedunhu, inobatsira kukwidziridzwa kwemhando yechiratidzo uye kubviswa kwema frequency asingadiwe, nemhedzisiro inova chiitiko chakawedzerwa kune mushandisi, sezvo ruzha rwakajeka, mifananidzo inopinza, uye data yakagadziriswa yakachengeteka zvakanyanya. Mune isina waya yekuchaja masisitimu, inductors inoita basa rakapetwa, mune inotapurirana uye inogamuchira, sechinhu cheiyo resonant inductive coupling process inogonesa kufambisa kwesimba munzvimbo isina majoi.
Ma inducers anoshandiswa munetiweki nemidziyo yekutaurirana zvakare. Kune ma routers uye modem, inductors inodiwa kuchengetedza chiratidzo chekuvimbika pane frequency spectrum kune yakasimba uye yakasimba internet chiratidzo. Iri rondedzero yakafara yezvishandiso inonongedza kukosha kwehunyanzvi hwema inductors uye zvakare inobatsira kune inoshanda rutivi rwetekinoroji muhupenyu hwezuva nezuva, uye nekuda kweizvi, inductors zvinhu zvinosungirwa mukugadzira uye kushanda kwemagetsi.
Power Supply Circuits
Mumaseketi emagetsi, chinhu chakakosha, chine kuchengetedzwa kwechinguva kwesimba iro inductance inaro, uye pfuma yekudzikisa shanduko yeazvino. Iwo anoshandiswa mune yakakwana dhizaini yekuchinja-modhi magetsi emagetsi (SMPS), ayo anoshandura simba nemazvo kubva kune sosi kuenda kune inodiwa voltage kana yazvino. Kuwedzerwa kwemainductor kune aya maseketi kunokonzeresa madiki, akareruka, uye akanyanya kushanda magetsi emagetsi, zvichienzaniswa nemaseketi anoshandisa capacitor chete, zvichiita kuti zvigoneke kune inotakurika application uko huremu uye hupenyu hwebhatiri zvinonyanya kunetseka.
