Diki Inductors Guide: Basics, Mabasa & Key Mashandisirwo

Kunzwisisa Diki Inductors

Nhanganyaya yeInductance

Inductance chinhu chakakosha chemaseketi emagetsi chine chekuita nekukwanisa kwewaya kuchengetedza simba mundima yemagineti kana magetsi achipfuura nepawaya. Madiki inductors, seaya ari muzviuru zvemagetsi, anoshandisa musimboti uyu kudzora ikozvino uye kusefa masaini. Kusimba kweinductor's magineti kunoenderana neiri kuyerera nepakati pamwe chete nezvimwe zvimiro zvemuviri senge nhamba yekutendeuka uye chimiro chepakati zvinhu. Iri ruzivo rwakakosha runobatsira kuratidza inowanikwa mune madiki inductors uye akasiyana maapplication mumagetsi emazuva ano.

Mhando dzeMadiki Inductors

Pane maitiro maviri ayo madiki inductors anogona kuiswa. Iyo yakakosha zvinhu uye kumisikidzwa, yega yega inokodzera kune chaiwo maapplication ayo anosanganisira magetsi ekupa kutsvedzerera uye chiratidzo chekugadzirisa. Iyo air-core, ferrite-core, uye toroidal inductors inowanzoshandiswa. Air-core inductors haina yakasimba magineti musimboti inokonzeresa kushoma inductance uye kurasikirwa ichiri pasi pemasimba epakati anoita kuti ave akakodzera kukwirisa frequency. Zvichakadaro, ferrite-core inductors ine magineti maitiro anobvumira yakakura inductance uye inogona kushandiswa nechinangwa chekudzvinyirira ruzha uye kushandura simba. Toroidal inductor, donut shaped, haina mhepo migero, iyo inogona kuita kuti inductor ibudise isingaenderani magineti uye nekudaro inogona kunge iine yakaderera kushanda uye kuburitsa EMI ruzha, yakanakira magetsi emagetsi maseketi.

Hunhu hweMadiki Inductors

Madiki inductors anoratidzirwa nemamwe akakosha paramita, anoti: inductance, yakayerwa ikozvino, kuramba uye mhando yemhando. Iyo yekuchengetera inductor inoratidzwa neiyo inductance, kazhinji muHenries (H). Iyo yakayerwa ikozvino inomiririra iyo yepamusoro ikozvino iyo inductor inogona kuitisa isina kuzara kana kuwandisa. Kurasikirwa kwesimba muinductor kunokonzerwa nekupikisa, uye kupikisa kuduku kuri nani kuitira kuti kuve nekushanda kwepamusoro. Uye pakupedzisira, iyo yakakwirira kukosha kweQ (kukodzera chinhu), iyo inonyatsoita iyo inductor inochengetedza uye kuburitsa simba (zvishoma kupera kwesimba sekupisa). Kunzwisisa kwakanaka kwezvinhu izvi kwakakosha kune vese mainjiniya nevanofarira zvemagetsi pakusarudza ma inductors ezvigadziriso zvavo, uye inovimbisa kuenderana kwavo nekuyedza / prototype uye ita chokwadi chekuti mashandiro avo akakwenenzverwa.

Kusarudza Right Diki Inductor

Zvinhu Zvokufunga nezvazvo

Kana zvasvika pakusarudza yakanakisa diki inductor yeprojekiti yako, pane akati wandei akakosha ekufunga pakutamba. Chiyero chinonyanya kukosha ndeye inductance, kureva kukosha iyo inductor inogona kuchengetedza nayo simba. Izvi zvinosangana nezvinodiwa zvedunhu rako pakuita kwayo kwese. Chechipiri, iyo inductor yazvino chiyero inogona kunge isingakanganwike. Ndiyo yepamusoro-soro ikozvino inductor inogona kutora pasina kushanda kwayo kukanganiswa, uye zvakakosha pakuchengetedza mamiriro ekushanda akachengeteka uye kudzivirira dunhu kuti risakuvadzwa nekupisa. Chekupedzisira, saizi yeinductor diki yakakosha kwakakosha, kunyanya mukuita compact apo nzvimbo iri paprimiyamu. Dambudziko nderekutsvaga chiyero chakanaka chezvinhu izvi zvekuti iwe unowana inductor inosangana nemagetsi uye emuviri zvinodiwa zvepurojekiti yako.

Kufananidza Inductor kune Application

Kuti uone iyo chaiyo inductor diki yechikumbiro chako, kuziva chaunoda chikamu chekuita kwakakosha. Yakasiyana-siyana emagetsi ekushandisa anoda akasiyana inductance hunhu, hwazvino uye saizi ye inductance. Semuenzaniso, dunhu rekupa magetsi rinogona kuda compact inductor ine yakakwira ikozvino uye kushoma inductance, nepo chiratidzo chekusefa application inogona kutengesa kure inductance chaiyo yekubata ikozvino. Kubatsira mukuita sarudzo, vagadziri vanopa yakakura madheti anotsanangura mashandiro einductor pasi pemamiriro akasiyana siyana. Pazasi pane pfupiso pfupi tafura yezvimwe zvakajairika maapplication, uye zvavanoda inductor:

Zvakajairika Kukanganisa Pakusarudza

Pakusarudzwa kwemadiki inductors, chimwe chinowanzoregeredzwa hunhu hunhu hwavo hwekuwanda. Inductor yakanaka kune yakaderera frequencies inogona kusashanda pamafafitera epamusoro nekuti kurasikirwa kwayo kwekudzivirira kunowedzera, kana kukosha kwayo kwepakati kwakadzikira. Imwezve gomba ndeye apo iyo mhando yemhando (Q) yeinductor inoregeredzwa Q inoyera kugona kweinductor kuchengeta nekusunungura simba. Iyi yakaderera Q factor inogona kukonzera kurasikirwa kwesimba, kunyanya mukushanda pamwero wakakwira. Kupfuurirazve, chete kana kuita kuti ese madiki inductors akwane mumuviri inopa kuti kuita kuti ikwane hakutarise kutarisana nehukuru hwemuviri hwenzvimbo inowanikwa pabhodhi redunhu inogona kudiwa ine njodzi redesigns kana kuita tradeoffs. Ramba wakajeka pane idzi misungo uye unakirwe nekubudirira kurinani pakusarudza zvikamu uye kugadzira maseketi.

Kuita Diki Inductors mumasekete

Basic Circuit Integration

Kutsvaga imwe dambudziko? Maminiti aya madiki akakosha pakusefa, simba rekuchengetedza uye kugadzira magineti. Kutanga nekubatanidzwa kwedunhu rekutanga, basa reinductor mukati medunhu rakakosha kubata. Semuenzaniso, mumagetsi emagetsi system, madiki inductors anogona kubatsira kudzikisa voltage ripples kuitira kuti awedzere kugadzikana kwemagetsi kubuda. Uyewo usakanganwa kutarisa zviyero zveinductor (inductance value, current rating ) iyo inofanira kufanana nedunhu. Imwe yembiru dzekutanga ndeyekuziva nzira yekutengesa uye (kana zvichidikanwa) kutaridzika kwezvikamu.

Advanced Techniques

Kana munhu achienderera mberi nekushandisa madiki inductors uye mamwe emhando yepamusoro matekiniki, maapplication anowedzera kuoma. Ipapo hunyanzvi hwekushandisa inductors munhevedzano kana yakafanana kana muchimiro chemono filar kana bi-filar winding kuti ipe inodiwa inductance uye impedance zvakare inova yakakosha. Uyezve, kuziva zvinhu izvi muRF application, senge RF-circuits, zvinoda kunzwisiswa kwemainductor maitiro muRF regime ayo anosanganisira mazwi akadai seganda maitiro uye parasitic capacitance. Matekiniki ekudzikisa izvi zvisingadiwe semuenzaniso maererano nekusarudza ma inductors anoratidza akakodzera zvinhu kana geometries ari kuwedzera kukosha. Mamwe madhizaini akaomesesa anogonawo kusanganisira tunable inductors, kana inductively vaviri panzvimbo yekutumira magetsi asina waya, zvakare kuomesa kuita.

Matambudziko Anowanikwa uye Mhinduro

Nekudaro, kusanganisa madiki inductors mumaseketi harisi basa riri nyore. Rimwe dambudziko rinonyatsozivikanwa ndere netsaona chizvarwa chekukanganiswa kwemagetsi (EMI) kunokonzerwa nekukwira kwekuchinja ma frequency mumaseketi akadai sema converter kana inverters. Vagadziri vanogona kudzikisira izvi nekudzivirira kana inductors ine yakaderera EMI emissions. Nyaya yechipiri ndeyefizikisi yemapuranga edunhu, ayo anomanikidzwa munzvimbo. Pano zvakakosha kusarudza saizi yakakodzera uye mhando yeinductor. Tafura inotevera inopfupisa matambudziko akajairika anoitika kana madiki inductors akashandiswa uye mazano anobvira ekugadzirisa nawo.
