Metal-oxide-semiconductor field-effect transistors (MOSFETs) yakashandura indasitiri yezvemagetsi, ikava zvikamu zveubiquitous mumaseketi akawanda. Nepo basa ravo rekutanga riri rekudzora nekukudza masaini emagetsi, maMOSFET anewo chinhu chinowanzo furatirwa asi chakakosha: iyo yemukati muviri diode. Iyi blog positi inoongorora mukati mekuoma kweMOSFET muviri diode, kutsvaga nzira dzekudzikisa kurasikirwa kwavo uye kuwedzera mashandiro edunhu rese.
Kunzwisisa MOSFET Muviri Diode Kurasikirwa
Iyo diode yemuviri, inherent parasitic junction mukati meMOSFET chimiro, inoratidza unidirectional ikozvino kuyerera, ichibvumira ikozvino kupfuura kubva kudhiraivha kuenda kunobva asi kwete zvinopesana. Kunyange ichishandira zvinangwa zvakakosha, diode yemuviri inogona kuunza kurasikirwa kwesimba kunoderedza kushanda kwedunhu.
Kurasikirwa Kwekufambisa: Munguva yeMOSFET's on-state, diode yemuviri inoitisa ikozvino munzira yekudzokera kumashure, ichigadzira kupisa uye kuburitsa simba.
Kuchinja Kurasikirwa: Panguva yeMOSFET yekuchinja shanduko, diode yemuviri inoitisa zvazvino panguva yekudzoreredza kudzoreredza nguva, zvichitungamira pakuchinja kurasikirwa.
Matanho ekudzikisa MOSFET Muviri Diode Kurasikirwa
Kusarudza MaMOSFET Akakodzera: Sarudza maMOSFET ane yakaderera body diode kumberi voltage uye reverse kudzoreredza nguva kuti uderedze conduction uye kushandura kurasikirwa, zvichiteerana.
Kugadziridza Zviratidziro zveDhivha: Shandisa masaini akakodzera gedhi dhiraivha kuti uderedze nguva iyo diode yemuviri inoitisa panguva yekuchinja, kuderedza kuchinja kwekurasikirwa.
Kushandisa Snubber Circuits: Shandisa snubber circuits, inosanganisira resistors uye capacitors, kubvisa simba rakachengetwa muparasitic inductances uye kuderedza voltage spikes, kuderedza kuchinja kwekurasikirwa.
Parallel Body Diodes: Funga kuenzanisa diodes ekunze neiyo diode yemuviri kugovera ikozvino uye kuderedza kupera kwemagetsi, kunyanya mumashandisirwo epamusoro-zvino.
Alternative Circuit Design: Mune zvimwe zviitiko, mamwe matunhu ematunhu epamusoro anobvisa kudiwa kwemuviri diode's conduction nzira inogona kutariswa kuti iwedzere kuderedza kurasikirwa.
Mabhenefiti ekuderedza MOSFET Muviri Diode Kurasikirwa
Kuvandudza Kubudirira: Kudzikisa kurasikirwa kwe diode yemuviri kunotungamira mukuwedzeredzwa kwese kwedunhu kushanda zvakanaka, kushandura mukushomeka kwesimba rekushandisa uye kuchengetedza simba.
Yakaderedzwa Heat Generation: Kuderedza kurasikirwa kunoderedza kupisa chizvarwa mukati meMOSFET uye zvakatenderedza zvikamu, kuvandudza mashandiro ekupisa uye kuwedzera hupenyu hwechikamu.
Kuvimbika Kwakawedzerwa: Kudzikira tembiricha yekushanda uye kuderedzwa kushushikana pane zvikamu zvinobatsira mukusimudzira kuvimbika kwedunhu uye hupenyu hurefu.
Mhedziso
MOSFET muviri diode, nepo kazhinji isingatariswe, inogona kukanganisa zvakanyanya kushanda kwedunhu uye kuita. Kunzwisisa kwakabva kurasikirwa kwe diode yemuviri uye kushandisa nzira dzekudzikisa dzinoshanda kwakakosha pakugadzira hunyanzvi hwemagetsi, hwakavimbika masisitimu. Nekutora matekiniki aya, mainjiniya anogona kukwirisa mashandiro edunhu, kuderedza mashandisirwo esimba, uye kuwedzera hupenyu hwemagadzirirwo avo emagetsi.
