MOSFET-yada ku jira Xakamaynta Gaadiidka Korontada

1, doorka MOSFET ee kontoroolka baabuurta korontada

Marka la eego shuruudaha fudud, matoorka waxaa kaxeeya hadda wax soo saarka eeMOSFET, mar kasta oo wax soo saarka hadda jira (si looga hortago MOSFET inay gubato, koontarooluhu wuxuu leeyahay ilaalinta xadka hadda), mar kasta oo uu xoog badan yahay matoorka, ayaa sii xoogeysanaya dardargelinta.

 

2, wareegga kontoroolka ee MOSFET's's state's's circuits

Habka furan, on state, off process, cut-off state, state breakdown.

Khasaaraha ugu weyn ee MOSFET waxaa ka mid ah beddelidda khasaaraha (habka shid iyo daminta), luminta korantada, khasaaraha jarista (oo ay sababto daadinta hadda, taas oo aan muuqan), lumista tamarta ba'an. Haddii khasaarahan lagu xakameeyo inta u dhexeysa MOSFET ee loo dulqaadan karo, MOSFET waxay u shaqayn doontaa si sax ah, haddii ay dhaafto xadka la dulqaadan karo, dhaawac ayaa dhacaya.

Khasaaruhu inta badan waa ka weyn yahay khasaaraha gobolka conduction, gaar ahaan PWM aan si buuxda u furan, ee heerka garaaca garaaca garaaca wadnaha (oo u dhiganta xaaladda dardargelinta bilowga ah ee gaariga korontada), iyo gobolka ugu dhaqsiyaha badan inta badan waa khasaaraha conduction waa. ka taliyaan.

3, sababaha ugu waaweynMOSdhaawac

Dul-joogta, hadda sare ee ay keento burburka heerkulka sare (joogtada joogtada ah ee hadda sare iyo degdegga ah ee garaaca wadnaha ee ay sababtay heerkulka isgoysyada ayaa ka sarreeya qiimaha dulqaadka); kororka xad-dhaafka ah, heerka qulqulka isha ayaa ka weyn korantada burburka iyo burburka; Burburka albaabka, sida caadiga ah sababtoo ah korantada albaabka waxaa waxyeelo u geysata dibadda ama wareegga wadista in ka badan inta ugu badan ee danab la ogol yahay (guud ahaan waxay u baahan yihiin danab albaabka in ka yar 20v), iyo sidoo kale dhaawaca korantada taagan.

 

4, MOSFET mabda'a beddelka

MOSFET waa qalab danab ku shaqeeya, ilaa iyo inta albaabka G iyo heerka isha S si ay u bixiyaan danab ku haboon inta u dhaxaysa heerka isha S iyo D samayn doonaa wareeg conduction dhexeeya heerka isha. Iska caabinta jidkan hadda ayaa noqda MOSFET iska caabin gudaha ah, ie, iska caabinta. Baaxadda iska caabinta gudaha ayaa asal ahaan go'aamisa heerka ugu sarreeya ee hadda socda ee gobolkaMOSFETChip ayaa u adkeysan kara (dabcan, sidoo kale waxay la xiriirtaa arrimo kale, ugu muhiimsan waa caabbinta kulaylka). Inta yar ee iska caabbinta gudaha, waa ka weyn yahay hadda.
