Sezvo mota itsva dzinoshandisa simba dzichikurumidza kushanduka-shanduka kusvika pakuchaja nekukurumidza, kuchaja nekuburitsa magetsi munzira mbiri, uye kubatana kwakanyanya, tekinoroji yeOBC iri mundege inovandudzwa - sisitimu yemagetsi ye800V high-voltage iri kufambira mberi ichienda kusisitimu ye1200V, uye dhizaini yepuratifomu yemagetsi yepamusoro inova hwaro hwekuchaja nekukurumidza.
01 Ndeipi basa rakakosha rinoitwa ne capacitor muOBC iri mubhodhi?
Muhurongwa hwebhatiri rine voltage yepamusoro, capacitor ndiyo "nzvimbo yekuchengetera simba uye yekusefa" yeOBC & DCDC, uye mashandiro ayo anosarudza zvakananga kushanda zvakanaka, kuwanda kwesimba uye kuvimbika kwehurongwa - kungave kuri kukanganisa kwepuratifomu ine voltage yepamusoro, kushanduka kwesimba rema frequency, kana mamiriro akaoma ekushanda kwesimba remativi maviri, capacitor inodiwa kuti irambe ichishanda zvakanaka pasi penzvimbo dzine voltage yepamusoro, frequency yepamusoro, uye tembiricha yepamusoro. Nokudaro, kusarudzwa kwema capacitor anodzivirira voltage yepamusoro uye ane simba rakawanda chinhu chakakosha pakusarudza mashandiro eOBC iri mubhodhi.
02 Ndezvipi zvakanakira zveYMIN capacitors pakushandisa?
Kuti ikwanise kugadzirisa zvinodiwa zvakasimba zveOBC&DCDC pasi pemasisitimu ane simba guru rekuti ma capacitor agone kumira nesimba guru, diki, kugara kwenguva refu, uye simba guru remagetsi, YMIN yakatanga matrix yechigadzirwa che capacitor chinoshanda zvakanyanya kuti ikwanise kusimbisa sisitimu yeOBC&DCDC yemotokari itsva dzemagetsi.
01Capacitor yemagetsi yemhando yealuminium electrolytic capacitor: "gadhi rinosimbisa voltage" rezviitiko zvine simba guru
· Voltage inomira yakasimba: Mukupindura matambudziko ekuchinja-chinja kwevoltage uye kukwirira kwevoltage kunowanzoitika muOBC, CW3H series horn capacitor ine dhizaini yakakwana yevoltage margin yekupa rutsigiro rwakasimba rwevoltage uye dziviriro yeovervoltage. Inoedzwa zvakanyanya kuti irambe yakasimba uye igare kwenguva refu isati yabuda mufekitori kuti ive nechokwadi chekuti inogara kwenguva refu uye yakavimbika muOBC applications.
· Kuramba simba remagetsi rine ma "ripple current" akawanda: Kana OBC ichishanda, simba remagetsi rinogadzirwa nekuda kwekuchinja simba kakawanda. Kana capacitor ye "liquid horn-type aluminum electrolytic capacitor" ikashandiswa ne "rated ripple current" ka1.3, kukwira kwekushisa kunoramba kwakasimba uye mashandiro echigadzirwa akagadzikana.
· Kuwanda kwesimba: Maitiro ekumonera riveting akakosha anovandudza simba remagetsi. Kugona kwacho kwakakwira ne20% kupfuura indasitiri pahuwandu hwakafanana. Nemagetsi akafanana uye kugona kwacho, kambani yedu idiki muhukuru, ichichengetedza nzvimbo yekuisa uye ichizadzisa miniaturization yemuchina wese.
02Capacitor ye electrolytic yealuminium inovhara mvura: "Kubudirira Kunobudirira" munzvimbo inopisa uye nzvimbo diki
Iyo LKD capacitor yemvura inovhara aluminium electrolytic capacitor inogona kugadziriswa kuti ishande zvakanaka nekuda kwekusakwana kwehuwandu hwemagetsi. Iyi sarudzo yakakodzera yekusefa kwemagetsi zvakanyanya uye kuchengetedza simba kwakavimbika kweOBC inosungirirwa mumotokari munzvimbo dzine magetsi akawanda, mafrequency akawanda uye dzakaoma.
· Kudzivirira kupisa kwakanyanya: Kusvika pakupisa kwekushanda kwe105℃ mupakeji diki, ichipfuura zvakanyanya ma capacitor ese ane kudzivirira kupisa kwe85℃, zvichipa dziviriro yakavimbika kune nzvimbo dzinoshandiswa kupisa kwakanyanya.
· Kuwanda kwe capacitance density: Pasi pe voltage yakafanana, kugona kwakafanana uye specifications dzakafanana, dhayamita nekukwirira kwe LKD series zvakaderera ne20% pane zvezvigadzirwa zve horn, uye kukwirira kunogona kuderera ne40%.
· Kushanda zvakanaka kwemagetsi uye kuvhara: Nekuda kwekugadzirwa kwayo kwekudzivirira kupisa kwakanyanya, ESR yakaderedzwa zvakanyanya, uye ine simba rekudzivirira ma ripple current. Zvinhu zvakasiyana zvekuvhara uye tekinoroji zvinoita kuti LKD isapinde mhepo kupfuura horn capacitor, ukuwo ichiwedzera hupenyu hwebasa, hunogona kusangana nezvinodiwa zve105℃ 12000 maawa.
03 Capacitor yemhando ye "Solid-liquid hybrid capacitor": "bhiriji rine nzira mbiri" pakati pekushanda zvakanaka uye kugadzikana
· Kuwanda kwe capacitance density: Kana tichienzanisa nema capacitor ane huwandu hwakafanana pamusika, capacitance yeYMIN solid-liquid hybrid capacitorsinowedzerwa neinopfuura 30%, uye kukosha kwe capacitance kwakagadzikana mukati me ±5% mu termperature yakafara. Mushure mekushanda kwenguva refu, kukosha kwe capacitance kwakagadzikana pa 90%.
· Kudonha kwakaderera zvakanyanya uye ESR yakaderera: Kudonha kwakaderera kunogona kudzorwa mukati me20μA, uye ESR inogona kudzorwa mukati me8mΩ, uye kuenderana kwezviviri zvakanaka. Kunyangwe mushure me260℃ high-temperature reflow soldering process, ESR uye kudonha kwakaderera zvinoramba zvakagadzikana.
04 Ma capacitor emafirimu: "chipingamupinyi chekuchengetedza" chinobatsira kurarama kwenguva refu uye kuvimbika zvakanyanya
Zvichienzaniswa nema capacitor emagetsi, mabhenefiti ekushanda kwema capacitor efirimu anoratidzwa nemagetsi anomira zvakanaka, ESR yakaderera, kusashanda zvakanaka, kushanda kwakagadzikana, uye hupenyu hurefu, izvo zvinoita kuti dhizaini yesystem yekushandisa ive nyore, kuramba kurira kwakanyanya, uye kuvimbika zvakanyanya munzvimbo dzakaoma.
· Voltage inotsungirira yakakwira zvakanyanya: kutsungirira voltage yakakwira inodarika 1200V, hapana chikonzero chekubatana kwakatevedzana, uye inogona kutsungirira voltage yekushanda yakayerwa ka1.5.
· Kugona kukuru kwe ripple: Kukwanisa kushivirira ripple ye3μF/A kwakapetwa ka50 kupfuura ma capacitor emagetsi echinyakare.
· Garandi yehupenyu hwese: anopfuura maawa 100,000 ehupenyu hwebasa, mhando yakaoma uye hapana nguva yekushanda. Mumamiriro akafanana ekushandisa,macapacitor efirimuvanogona kuchengetedza mashandiro avo kwenguva yakareba.
Mune ramangwana, YMIN icharamba ichinyatsoongorora tekinoroji yemagetsi ane simba rakawanda uye yakabatanidzwa ye capacitor kuti ipe simba rinoshanda uye rakavimbika kune masisitimu eOBC & DCDC emotokari itsva dzemagetsi!
