Gate Vatyairi

Mutyairi wegedhi isimba rekusimudzira simba rinogamuchira yakaderera-simba kupinza kubva kune controller IC uye rinogadzira yakakwira-yazvino dhiraivha yekupinda gedhi repamusoro-simba transistor senge IGBT kana simba MOSFET.Madhiraivha egedhi anogona kupihwa kungave pa-chip kana se discrete module.Muchidimbu, mutyairi wegedhi ane danho rekuchinja pamwe chete neamplifier.Mutyairi wegedhi IC anoshanda sechiratidziro pakati pemasaini ekudzora (dhijitari kana analog controllers) uye magetsi switch (IGBTs, MOSFETs, SiC MOSFETs, uye GaN HEMTs).Iyo yakabatanidzwa gedhi-mutyairi mhinduro inoderedza dhizaini yakaoma, nguva yekusimudzira, bhiri rezvinhu (BOM), uye nzvimbo yebhodhi uku ichivandudza kuvimbika pamusoro pezvigadziriso-zvinoitwa gedhi-drive mhinduro.

Nhoroondo

Muna 1989, International Rectifier (IR) yakaunza yekutanga monolithic HVIC gedhi mutyairi chigadzirwa, iyo yakakwira-voltage yakabatanidzwa yedunhu (HVIC) tekinoroji inoshandisa patented uye proprietary monolithic zvimiro zvinosanganisa bipolar, CMOS, uye lateral DMOS zvishandiso zvine kuparara kwemagetsi pamusoro pe700 V uye 1400. V yekushanda offset voltages e600 V uye 1200 V. [2]

Uchishandisa iyi yakasanganiswa-signal HVIC tekinoroji, ese akakwira-voltage level-shifting maseketi uye yakaderera-voltage analogi uye dijitari maseketi anogona kuitwa.Nekugona kuisa yakakwira-voltage wedunhu (mu 'tsime' rakaumbwa ne polysilicon mhete), iyo inogona 'kuyangarara' 600 V kana 1200 V, pane imwecheteyo silicon kure nekusara kweyepasi-voltage wedunhu, kumusoro-kurutivi. simba MOSFETs kana IGBTs aripo mune dzakawanda dzakakurumbira off-line redunhu topologies senge buck, synchronous boost, hafu-bhiriji, yakazara-bhiriji uye matatu-chikamu.Vatyairi vegedhi reHVIC vane ma switch anoyangarara akanyatsokodzera matopology anoda kumusoro-side, half-bridge, and three-phase configurations.[3]

Chinangwa

Kusiyana nebipolar transistors, maMOSFET haadi kugara achipinza magetsi, chero asiri kubatidzwa kana kudzima.Iyo yakasarudzika gedhi-electrode yeMOSFET inoumba acapacitor(gedhi capacitor), iyo inofanirwa kuchajwa kana kuburitswa pese painobatidzwa kana kudzimwa MOSFET.Sezvo transistor inoda imwe gedhi voltage kuitira kuti ibatike, iyo capacitor yesuwo inofanirwa kubhadhariswa kune kanenge inodiwa gedhi voltage kuti transistor ibatiswe.Saizvozvo, kudzima transistor, mutero uyu unofanirwa kubviswa, kureva kuti gedhi capacitor rinofanira kuburitswa.

Kana transistor ichivharwa kana kuvharwa, haichinji nekukurumidza kubva kune isiri-kuitisa kuenda kune inoitisa nyika;uye inogona kutsigira nekufamba kwenguva magetsi akakwira uye kuitisa yakakwira ikozvino.Nekuda kweizvozvo, kana gedhi ikozvino rinoiswa kune transistor kuita kuti ichinje, imwe huwandu hwekupisa hunogadzirwa hunogona, mune dzimwe nguva, hwakakwana kuparadza transistor.Naizvozvo, zvinodikanwa kuchengeta nguva yekuchinja ipfupi sezvinobvira, kuitira kuti uderedzekuchinja kurasikirwa[de].Nguva dzekuchinja dziri muhuwandu hwemamicroseconds.Nguva yekushandura ye transistor inopesana nehuwandu hwehuwandu hwecurrentaimbochaja gedhi.Nokudaro, kuchinja kwezvino kunowanzodiwa muhuwandu hwemazana akawandamilliamperes, kana kunyange pakati peamperes.Kune akajairika gedhi voltages anosvika 10-15V, akati wandeiwattsyesimba inogona kudikanwa kutyaira switch.Kana mafungu mahombe achichinjirwa pama frequency akakwira, semuenzaniso inDC-ku-DC converterskana kuti chikurumota dzemagetsi, akawanda transistors dzimwe nguva anopiwa mukufanana, kuitira kuti ape zvakakwana zvakakwirira zvekuchinja zvino uye simba rekushandura.

Chiratidzo chekushandura che transistor chinowanzogadzirwa ne logic circuit kana amicrocontroller, iyo inopa chiratidzo chekubuda icho kazhinji chinongogumira kune mashoma milliampere ezvino.Nekuda kweizvozvo, transistor iyo inotyairwa zvakananga nechiratidzo chakadaro inochinja zvishoma nezvishoma, pamwe nekurasikirwa kukuru kwesimba.Panguva yekuchinja, iyo gedhi capacitor ye transistor inogona kudhirowa ikozvino nekukurumidza zvekuti inokonzera yazvino overdraw mu logic circuit kana microcontroller, zvichikonzera kupisa kunotungamirira kukukuvara zvachose kana kuparadzwa zvachose kwechip.Kuti izvi zvisaitike, mutyairi wegedhi anopiwa pakati peiyo microcontroller inobuda chiratidzo uye transistor yemagetsi.

Chaja pombikazhinji inoshandiswa muH-Bridgesmune vatyairi vepamusoro vegedhi vanotyaira yakakwira side n-channelsimba MOSFETsuyeIGBTs.Midziyo iyi inoshandiswa nekuda kwekuita kwayo kwakanaka, asi inoda gedhi drive voltage mashoma mavolts pamusoro penjanji yemagetsi.Kana pakati pehafu yebhiriji yadzikira iyo capacitor inochajwa kuburikidza ne diode, uye iyi charge inoshandiswa gare gare kutyaira gedhi reparutivi rwepamusoro FET gedhi mashoma volts pamusoro penzvimbo kana emitter pini's voltage kuitira kuti ibatike.Iri zano rinoshanda nemazvo chero bhiriji richigara richichinjika uye rinodzivirira kuomarara kwekumhanyisa magetsi ega uye inobvumidza iyo inoshanda zvakanyanya n-channel zvishandiso kuti zvishandiswe kune ese ari maviri epamusoro uye akaderera switch.
