Simba RakaumbwaVagadziri, pamwe chete neruzivo rwemazuva ano rwetekinoroji yeindasitiri uye nzvimbo dzekudzora mhando, gwara iri rinofukidza huwandu hwakakwana hwezvinyorwa kubva pamisimboti yekutanga, maitiro ekushandisa kusvika pakusarudza chaiko uye kudzivirira matambudziko, kuita sarudzo dziri nani mukugadzira magetsi. Ngatienderere mberi nehurukuro kubva muchinyorwa chapfuura (nguva yekupedzisira takakurukura mibvunzo mitanhatu)
7. Chii chinonzi "kukundikana kuramba kumanikidzwa"? (Dambudziko guru mukusarudza!)
Iri i "gomba rakavanzika" risingafungidzike zviri nyore. Pane jira rinodzivirira kupisa pakati pesimbi yehupfu hwesimbi mukati mechikamu chakaumbwa.inductor.
* Dambudziko: Munzvimbo dzinoshanda dzine voltage yakawanda uye dzinoshanda kakawanda kwenguva refu, kana simba rekudzivirira risina kukwana, jira rekudzivirira riri pakati pesimbi rinogona kubhoorwa.
* Mhedzisiro: Zvakafanana nekubatanidza resistor iri padivi rimwe cheteinductor, zvichikonzera kuwedzera kwakanyanya kwekurasikirwa kwemukati, kupisa kwakanyanya, uye kunyange kupisa kwema chips.
*Dzivisa njodzi: Mukushandiswa uko voltage yekupinda inodarika 50V, gara uchisimbisa chiyero chevoltage yeinductornemugadziri, kwete chete kukosha kweinductance.
8. Chii chinonzi Isat neIrms? Ndeipi inofanira kufungwa nezvayo panguva yekusarudza?
Aya ndiwo ma parameter maviri akakosha emazuva ano:
* Isat (Saturation Current): Iyo current kana inductance yadzikira kusvika padanho rakati (semuenzaniso, 30%). Kupfuura kukosha uku kunokonzera kudzikira kamwe kamwe kwesimba reinductor rekuchengetedza simba, zvichikonzera kusagadzikana mu power loop.
* Irms (RMS current): Iyo current iyo tembiricha yepamusoro yeinductor inosvika pamutengo wakatarwa (semuenzaniso, 40°C), inonyanya kutsanangurwa nekurasikirwa kwemhangura (DCR).
* Musimboti: Pakusarudza, ma parameter ese ari maviri anofanira kusangana nezvinodiwa zvedunhu.
9. Ko kuramba kweDCR (DC resistance) kwakaderera nguva dzose kuri nani here?
Ehe. Kana DCR yakaderera, kurasikirwa kwemhangura kudiki, kushanda kwesimba remagetsi kwakawedzera, uye kukwira kwetembiricha kwakaderera. Zvisinei, kune huwandu humwe chete, kutevera DCR yakaderera zvakanyanya kunowanzoreva kudzikira kwe inductance, iyo inoda kutengeserana zvichibva pane mamiriro chaiwo ekushandiswa (kungave kuri kukoshesa kushanda kwepamusoro kana kuchengetedza simba rakakura).
10. Maitiro ekutonga mhando yeinductor ?
Kutonga kwekutanga kunogona kuitwa kuburikidza nepfungwa dzinotevera:
*Kutaridzika: Pamusoro pechinhu chinofanira kunge chakati sandara uye chakapfava, chisina maburi kana mitswe, uye chifukidziro chepini chinofanira kupenya.
*Simba rePin: Ma terminals akasungirirwa anofanira kunge akasimba uye asingatyoke nyore.
*Kudzivirira kusungirirwa: Mushure mekusungirirwazve, muviri haufanirwe kuve neruvara rwakajeka kana mitswe.
11. Nei zvichigona kubatanidzwama inductorskuitwa kudiki uye kutetepa?
A: Nekuda kwetekinoroji yesimbi yeupfu, haidi nzvimbo dzakachengetwa dzekubatanidza magineti semainductors echinyakare, uye chimiro chayo chakanyanya kusimba. Parizvino, tekinoroji inogona kugadzira zvigadzirwa zvakatetepa zvakanyanya zvine ukobvu husingasviki 0.5mm, izvo zvakakodzera kwazvo kumafoni nemidziyo inopfekwa.
12. Chii chinonzi "T-Core" maitiro?
Iyi tekinoroji yepamusoro inovandudza kugoverwa kwemagetsi kuburikidza nekushandisa ma molds chaiwo uye nzira dzekumonera, zvichideredza kurasikirwa uye kuvandudza mashandiro emagetsi akawanda uye kushanda zvakanaka kwekupisa.
13. Ko inductor yakabatanidzwa ichaita ngura here?
Zvinhu zvakagadzirwa zvinongova upfu hwesimbi. Kana chifukidziro chekudzivirira (senge epoxy resin) pamusoro pechigadzirwa chikapfapfaidzwa zvisina kuenzana kana kukuvara, pane njodzi yekuoxidation uye ngura munzvimbo dzine hunyoro hwakawanda uye munyu. Tekinoroji yekupfapfaidza otomatiki yemhando yepamusoro inogona kudzivirira dambudziko iri zvinobudirira.
