Ndezvipi zvakajairika inductors | GETWELL

Kufanana nemaresistors uye capacitors, inductors ndeimwe yeanonyanya kushandiswa passive zvishandiso mudhizaini dhizaini. Inductor chinhu chekuchengetedza simba, chinogona kushandura simba remagetsi uye magineti simba kune rimwe nerimwe, uye rinonyanya kuita basa mukusefa, oscillating, kudzikamisa ikozvino uye kudzora kukanganiswa kwemagetsi mudunhu. Kana inductors ichishandiswa mudunhu iri, iwe unofanirwa kuziva aya ma parameter einductor!

Paunotarisa mamwe edunhu schematics, iwe uchaona kuti inductance zviratidzo zvinoshandiswa mudunhu. Mushure mekutarisa parameters pachiratidzo, ndakatonyanya kuvhiringidzika. Iyo unit ye ​​inductor yakava OHM rinhi? Zvechokwadi, iyi haisi inductor, asi magnetic bead. Tevere, isu tichawedzera ruzivo nezve musiyano uye kubatana pakati pemainductors nemagineti bead.

Kutanga tsanangura basa remagineti bead mudunhu, iro rakakura basa reakateedzana magineti bead mumutsara wekutumira chiratidzo kudzvanya chiratidzo chekupindira, kubva padanho rekuona, magineti mabedhi anogona kuenzana neinductor, ona kuti izvi. iri nyore inductor. Iyo chaiyo inductor coil yakagovera capacitance, ndiko kuti, inductor yatinoshandisa yakaenzana neinductor yakabatana mukufanana neyakagoverwa capacitor.

Mhedziso yeInductance

Nechepfungwa, kudzvanyirira iyo yakaitwa yekupindira chiratidzo, inodiwa kuti iyo yakakura kuwanda kweiyo inductance, zviri nani, asi kune iyo inductor coils , iyo yakakura inductance, yakakura kugoverwa kwecapacitance yeinductor coil, uye mhedzisiro yezviviri. vachabvisa mumwe nemumwe kunze.

Pakutanga, iyo impedance inductor coil inowedzera nekuwedzera kwehuwandu, asi kana kusagadzikana kwayo kunowedzera kusvika pakakwirira, iyo impedance inoderera nokukurumidza nekuwedzera kwehuwandu, iyo inokonzerwa nemigumisiro yeparallel distributed capacitance. Kana iyo impedance ichiwedzera kusvika pakakwirira, ndiyo nzvimbo iyo iyo yakagoverwa capacitance yeinductor coil inopindirana neakaenzana inductor mukufanana. Iyo yakakura iyo inductance yeinductor coil ndeye, yakaderera iyo resonant frequency ndeye. Kana isu tichida kuwedzera kuvandudza kudzvinyirira frequency, ipapo sarudzo yekupedzisira yeinductor coil ichafanirwa kunge iri diki muganhu, iyo magnetic bead, kureva, kuburikidza-moyo inductor, inductor coil ine isingasviki 1 kutendeuka. Nekudaro, iyo yakagoverwa capacitance ye--core-inductor yakapetwa kakawanda kusvika kakapetwa kakawanda pane iyo ye-single-loop inductor coil, saka iyo frequency yekushanda ye---moyo inductor yakakwirira kupfuura iyo ye-single-loop inductor coil. . Iyo inductance yemagineti beads kazhinji idiki, ingangoita pakati pema microbead mashoma uye akawanda e microbeads. Kumwe kushandiswa kwemagineti mabedhi kuita emagetsi ekudzivirira, ayo emagetsi ekudzivirira emagetsi ari nani pane kudzivirira mhedzisiro yewaya yekudzivirira, iyo vanhu vazhinji vasingatarise zvakanyanya. Nzira yekushandiswa ndeyekutendera kuti waya mbiri dzipfuure nepakati pemagineti bead, saka kana paine magetsi anoyerera achibuda muwaya mbiri, magineti mazhinji achange akaiswa mumagineti beads, uye magineti. munda hauchapenya kunze. Nekuti iyo magineti inogadzira eddy ikozvino mune iyo magineti bead, kutungamira kweiyo eddy ikozvino inogadzira tambo yemagetsi inongopesana neiyo tambo yemagetsi pamusoro peiyo conductor, iyo inogona kupesana. Naizvozvo, iyo magineti bead inewo inodzivirira pamunda wemagetsi, ndiko kuti, iyo magineti bead ine simba rekudzivirira mhedzisiro pamagetsi emagetsi mune conductor.

Chakanakira kushandisa magineti mabedhi ekudzivirira kwemagetsi nderekuti magineti mabedhi haafanire kudzikwa, uye dambudziko rekuisa pasi rinodiwa newaya yekudzivirira rinogona kudzivirirwa. Kushandisa magineti beads se electromagnetic shielding, kune kaviri waya, zvakaenzana nekubatanidza yakajairika-modhi yekudzvinyirira inductor mumutsara, iyo ine yakasimba kudzvinyirira mhedzisiro pane yakajairika-modhi yekukanganisa masaini.

Zvinogona kuonekwa kuti inductor coil inonyanya kushandiswa kuEMI kudzvinyirira kwepasi-frequency interference signals, nepo magineti mabhedhi achinyanya kushandiswa kuEMI kudzvinyirira kwepamusoro-frequency interference signals. Naizvozvo, kune EMI kudzvanya kweiyo yakafara-bhendi yekupindira chiratidzo, akati wandei inductors ezvivakwa zvakasiyana anofanirwa kushandiswa panguva imwe chete kuti ishande. Pamusoro pezvo, kudzvanyirira iyo yakajairika modhi yakaitwa yekukanganisa chiratidzo neEMI, isu tinofanirawo kutarisisa kudzvanyirira chinzvimbo chekubatanidza pakati peinductor neY capacitor. Iyo Y capacitor uye kudzvanya inductor inofanirwa kunge iri padyo sezvinobvira kune inopinza yemagetsi, ndiko kuti, nzvimbo yekubuda kwemagetsi, uye iyo yakakwira frequency inductor inofanira kunge iri padyo sezvinobvira kune Y capacitor, nepo Y capacitor. inofanira kuva pedyo sezvinobvira waya yepasi yakabatana nepasi (waya yepasi yetambo yemagetsi matatu-yakakosha), iyo inoshanda kune EMI kudzvanya.

Izvo zviri pamusoro ndiko kusuma kwema common inductors, kana iwe uchida kuziva zvakawanda nezve inductors, ndapota inzwa wakasununguka kutibata nesu.
