Kunzwisisa basa uye chimiro cheMOSFETs

Kana iyo transistor inogona kunzi yakanyanya kugadzirwa muzana remakore rechi20, saka hapana mubvunzo kutiMOSFET umo chikwereti chikuru. 1925, pamisimboti yekutanga yeMOSFET patents yakaburitswa muna 1959, Bell Labs yakagadzira musimboti weMOSFET zvichibva pane dhizaini. Kusvika nhasi, makuru kune emagetsi anoshandura, madiki kundangariro, CPU uye zvimwe zvemagetsi zvigadzirwa zvepakati, hapana kana chimwe chazvo chisingashandisi kuMOSFET. saka chinotevera tinonzwisisa basa rechimiro cheMOSFET icho! MOSFET zita rakazara ndiMetal-Oxide-Semiconductor Field-Effect Transistor.

1. Basa guru reMOSFETs

The basic keyword about MOSFET is - semiconductor, and semiconductor is a kind of metal material, inogona kuitisa magetsi, asi kutaura zvazviri, inogonawo kuiswa insulated.MOSFET as a kind of semiconductor device, tinoida kuti tizive basa re nyore. inonyanya kuve nekukwanisa kuve nechokwadi chekuti kutenderera kwedunhu, uye zvakare kukwanisa kuona dunhu rekuvhara.

2. Basic chimiro cheMOSFETs

A MOSFET chishandiso chemagetsi chinogoneka zvakanyanya nekuda kwesimba rayo rakaderera gedhi dhiraivha, yakanakisa yekumhanyisa kumhanya uye kushanda kwakasimba kwakafanana. Mazhinji masimba eMOSFET ane longitudinal yakatwasuka chimiro, ine sosi uye inonyura mune dzakatarisana nendege dzewafer, ichibvumira mahombe emhepo kuyerera uye ma voltages akakwira kuiswa.

3. MaMOSFET anonyanya kushandiswa semidziyo yemagetsi yakawanda mundima mbiri

(1), zvinodikanwa zvenguva yekushanda pakati pe10kHz ne70kHz, nepo simba rekubuda rive risingasviki 5kw mumunda, muhuwandu hwakawanda hwezviitiko mundima iyi, kunyangwe IGBT nesimba.MOSFETs inogona kuita basa rinoenderana, asi simba reMOSFETs rinowanzovimba nekurasikirwa kwekuchinja kwepasi, saizi diki uye mutengo wakaderera kuti uve sarudzo yakakwana, zvikumbiro zvemumiriri iLCD TV mabhodhi, induction cookers zvichingodaro.

(2), izvo zvinodikanwa zveiyo frequency yekushanda zvakakwira kupfuura iyo yepamusoro frequency inogona kuwanikwa nemamwe magetsi emagetsi, iyo yazvino yakanyanya frequency iri kunyanya mu70kHz kana zvakadaro, munzvimbo ino simba.MOSFET yave iyo yega sarudzo, mumiriri zvikumbiro inverters, odhiyo midziyo, zvichingodaro.
