N mhando, P mhando MOSFET inoshanda musimboti wechinhu chimwe chete, MOSFET inonyanya kuwedzerwa kudivi rekupinza regedhi voltage kuti ibudirire kudzora divi rekubuda kwemvura yazvino, MOSFET mudziyo unodzorwa nemagetsi, kuburikidza nemagetsi akawedzerwa. kugedhi kudzora hunhu hwechishandiso, kusiyana neiyo triode kuita shanduko nguva nekuda kweiyo base ikozvino yakakonzerwa nechaji yekuchengetedza maitiro, mukuchinja maapplication, MOSFET's Mukuchinja maapplication,MOSFET's kasidhi yekuchinja inokurumidza kupfuura iya yematatu.
Mumagetsi ekuchinja, anowanzo shandiswa MOSFET yakavhurika dhirivha yedunhu, iyo dhiraivha yakabatana kune mutoro sezvairi, inonzi open drain, open drain circuit, mutoro wakabatana nekukwirira kwevoltage, inokwanisa kubatika, dzima mutoro wazvino, ndiyo yakanaka analog switching mudziyo, inova musimboti weMOSFET kuita switching zvishandiso, iyo MOSFET kuita switching muchimiro chemamwe maseketi.
Panyaya yekuchinja magetsi ekushandisa, iyi application inoda MOSFETs kuitisa nguva nenguva, kudzima, senge DC-DC magetsi emagetsi anowanzo shandiswa mune yekutanga buck converter anovimba maviri MOSFETs kuita switching basa, switch idzi dzakachinjika muinductor kuchengetedza simba, kusunungura simba kumutoro, kazhinji kusarudza. mazana e kHz kana kutopfuura 1 MHz, kunyanya nekuti iyo yakakwira frequency ipapo, idiki magineti zvikamu. Panguva yekushanda kwakajairika, iyo MOSFET yakaenzana nekondukita, semuenzaniso, maMOSFET ane simba, madiki-voltage MOSFETs, maseketi, magetsi ndiko kushoma conduction kurasikirwa kweMOS.
MOSFET PDF parameters, vagadziri veMOSFET vakabudirira kutora iyo RDS (ON) parameter kutsanangura iyo on-state impedance, yekuchinja maapplication, RDS (ON) ndiyo inonyanya kukosha hunhu hwechishandiso; madheti anotsanangura RDS (ON), gedhi (kana dhiraivha) voltage VGS uye ikozvino inoyerera kuburikidza nekuchinja ine hukama, kune yakaringana gedhi drive, RDS (ON) inotaridzika yakamira parameter; MOSFETs anga ari mukufambisa anowanzoita chizvarwa chekupisa, uye zvishoma nezvishoma kuwedzera kwekushisa kwejunction kunogona kukonzera kuwedzera kweRSS (ON);MOSFET madheti anotsanangura iyo thermal impedance parameter, iyo inotsanangurwa sekugona kweiyo semiconductor junction yeMOSFET package yekubvisa kupisa, uye RθJC inongotsanangurwa seyekusangana-kune-kesi thermal impedance.
1, kuwanda kwacho kwakanyanyisa, dzimwe nguva kumhanyisa-kutevera vhoriyamu, kunotungamira zvakananga kune yakakwira frequency, MOSFET pakurasikirwa inowedzera, iyo yakanyanya kupisa, usaite basa rakanaka reyakakwana kupisa disipation dhizaini, yakakwira ikozvino, iyo yezita. kukosha kwazvino kweMOSFET, kudiwa kwekunaka kwekupisa kupisa kuti ukwanise kuwana; ID ishoma pane yakanyanya ikozvino, inogona kunge yakakomba kupisa, kudiwa kweakakwana ebetsero heatsinks.
2, MOSFET kusarudzwa kukanganisa uye kukanganisa mukutonga kwesimba, MOSFET yemukati kuramba haina kutariswa zvizere, inotungamira zvakananga mukuwedzera switching impedance, kana uchibata neMOSFET matambudziko ekupisa.
3, nekuda kwematambudziko ekugadzira dunhu, zvichikonzera kupisa, kuitira kuti MOSFET ishande mumutsara wekushanda, kwete mukuchinja, chiri chikonzero chakananga chekudziya kweMOSFET, semuenzaniso, N-MOS ita switch, iyo G- level voltage inofanira kuva yakakwirira kudarika simba rekushandisa neV vashoma, kuitira kuti ikwanise kunyatsoita, iyo P-MOS yakasiyana; pasina kuvhurika zvakakwana, kudonha kwemagetsi kwakakura kwazvo, izvo zvinozoguma nekushandiswa kwesimba, iyo yakaenzana DC impedance yakakura, kudonha kwemagetsi kuchawedzerawo, U * Ini ndichawedzerawo, kurasikirwa kuchaita kuti kupisa.
