Ndeupi musiyano uripo pakati peinductor neMagnetic beads | GETWELL

Iyo inogona kuoneka kubva kune impedance hunhu curve yemagineti bead kuti kuwanda kwenzvimbo yekuchinja kwakadzikira pane inductance, uye kuwanda kwenzvimbo yekuchinja kwakakwira kupfuura kupikisa. Basa re inductance kuratidza ruzha, nepo kuramba kunotora ruzha uye kuchishandura kuita kupisa. Chii chinonzi inductors uye magineti beads zvakafanana? Misiyano yavo ndeipi? Ngatitevere nevagadziri ve inductor kuti tinzwisise!

Musiyano uripo pakati peinductor uye magineti bead

1. Sensors zvinhu zvekuchengetedza simba, uye magineti mabhedhi ndiwo magetsi ekushandura (kushandisa) zvishandiso. Mafirita anogona kushandisa inductors uye bead, asi nenzira dzakasiyana. Inductor kusefa inoshandura simba remagetsi kuita remagineti simba, iro rinokanganisa dunhu munzira mbiri: nekushandura simba remagetsi kudzoka kuita simba remagetsi, uye nekupenya kunze-seEMI (EMI). Uyezve, simba remagetsi rinoshandurwa kuita simba rekupisa pasina kupindira kwechipiri kudunhu.

2. Sefa yekusefa yeinductor yakanaka kwazvo mu low frequency bhendi, asi kana kusefa kwekuita kwapfuura 50MHz, iyo magnetic bead inoshandisa iyo impedance chikamu kushandura ruzha rwepamusoro-ruve simba rekupisa, uye yawana chinangwa chekubvisa iyo yakakwirira. -frequency ruzha zvachose.

3. Kubva pachikamu cheEMC(EMC), magineti mabedhi anogona kushandura ruzha rwepamusoro-soro kuita simba rekupisa, saka vane simba rekudzivirira mwaranzi. Iwo anowanzo shandiswa anti-EMI zvishandiso uye anowanzo shandiswa kusefa mushandisi interface masaini. Simba sefa yehigh speed wachi mudziyo uri pabhodhi.

4. Kana iyo inductor uye capacitor ichigadzira yakaderera pass sefa, kusanganiswa kwezvikamu zviviri izvi zvinogona kuburitsa kuzvida-excitation nekuti zvese zviri zviviri zvikamu zvekuchengetedza simba; Magnetic beads midziyo yekubvisa simba uye haiburitse kuzvifadza paunenge uchishanda nema capacitor.

5. Kazhinji kutaura, iyo yakatemerwa ikozvino yeinductor inoshandiswa pakugadzirisa magetsi inenge yakakwirira, saka mumagetsi ekugadzirisa magetsi anoda high current, zvakadai sekushandiswa kwemagetsi module filtering; Magnetic beads anowanzo shandiswa chete kune chip-level magetsi mafirita (zvisinei, kwatove nehukuru hwazvino ratings pamusika).

6. Zvose magineti beads uye inductors ane DC kuramba, nepo dc kuramba magineti bead idiki zvishoma pane kusefa kuita, saka kusiyanisa kudzvanywa kwemagineti mabedhi idiki kana ichishandiswa mukusefa kwesimba.

7. Kana yakashandiswa pakusefa, kushanda ikozvino kweinductor kwakaderera pane yakarongwa ikozvino, kana zvisina kudaro iyo inductor inogona kunge isingakuvadzi, asi inductance value ichave yakarerekera.

Nzvimbo yakajairika yeinductor uye magineti bead

1. Yakatemerwa ikozvino. Kana iyo ikozvino yeinductor inopfuura iyo yakarongerwa ikozvino, iyo inductance ichaderera nekukurumidza, asi iyo inductor haina kukuvadzwa, uye iyo magineti bead inoshanda ikozvino inodarika yakayerwa ikozvino, ichakonzera iyo magineti bead kukuvara.

2. Dc kuramba. Kana ichishandiswa mumutsara wemagetsi, pane imwe ikozvino pamutsara, kana dc kupikisa kweinductor kana magnetic bead pachayo yakakura kwazvo, ichabudisa imwe voltage drop.

3. Frequency characteristic curve. Iyo data yekugadzira ye induction bhora uye magineti bhora yakasungirirwa neiyo mudziyo frequency maitiro curve. Kuti usarudze mudziyo wakakodzera unofanirwa kunyatso tarisa kune macurves aya kuti usarudze mudziyo wakakodzera. Kana yashandiswa, teerera kune yayo resonant frequency.

Pamusoro pane kuunzwa kwemainductors uye magineti bead, kana iwe uchida rumwe ruzivo nezve inductors, ndapota taura nevanopa inductor vatengesi vedu.
