Bir-oxide-semiconductor field-effect transistors (MOSFETs) waxay noqdeen qaybo lagama maarmaanka u ah qalabka elektaroonigga ah ee casriga ah, taas oo ay ugu wacan tahay awoodooda beddelidda sare iyo hufnaanta. Ku dhex milmay qaab-dhismeedka MOSFET waxa ku jira shay inta badan la iska indho-tiray oo haddana muhiim ah: diode-ka jirka. Qaybtan muhiimka ah ayaa door muhiim ah ka ciyaarta ilaalinta wareegga iyo waxqabadka. Si kastaba ha ahaatee, MOSFET diode-yada jirka waxay ku dhici karaan guuldarro, taasoo u horseedda cillado wareegga wareegga iyo khataraha badbaadada. Fahamka sababaha caadiga ah ee fashilka awoodda MOSFET diode ayaa muhiim u ah qaabeynta hababka elektaroonigga ah ee la isku halayn karo oo adag.
Soo Bandhigidda Sababaha Xididada ee Awoodda MOSFET Diode
Cadaadiska Xad-dhaafka ah: Ka-dhaafitaanka heerka dambe ee diode-ka jirka waxay u horseedi kartaa burbur lama filaan ah, taasoo keenta dhaawac aan laga soo kaban karin oo soo gaara isgoyska diode. Tani waxay ku dhici kartaa koronto ku meel gaadh ah, danab ku dhaca, ama nakhshad wareeg aan habboonayn.
Cadaadiska Joogtada ah: Ka-dhaafitaanka awoodda wax-ka-qabashada hore ee diode-ka jirka waxay keeni kartaa kuleyl xad-dhaaf ah, taasoo keenaysa isku-xidhka diode-ku inuu dhalaaliyo ama hoos u dhaco. Tani waxay dhici kartaa inta lagu jiro dhacdooyinka beddelka sare ee hadda ama xaaladaha wareegga gaaban.
Cadaadiska Beddelka soo noqnoqda: beddelka soo noqnoqda ee MOSFET ee soo noqnoqoshada sare waxay keeni kartaa daal isku xidhka diode-ka jirka, taasoo keenta dildilaacyo yaryar iyo ugu dambayntii guuldarro. Tani waxay si gaar ah ugu badan tahay codsiyada ku lug leh beddelka soo noqnoqda ee sarreeya iyo culaysyada soo kicinta.
Sababaha Deegaanka: Soo-gaadhista xaaladaha adag ee deegaanka, sida heerkulka xad-dhaafka ah, qoyaanka, ama walxaha wasakhaysan, waxay soo dadajin karaan nabaad-guurka is-goysyada diode-ka jirka, taasoo horseedda fashil degdeg ah.
Cilladaha Wax-soo-saarka: Marar dhif ah, cilladaha wax-soo-saarka, sida wasakhda ama cilladaha qaab-dhismeed ee isgoyska diode, waxay u horseedi karaan diode-ka jirka inuu guuldareysto.
Xeeladaha Looga Hortagayo Awoodda MOSFET Diode Failure
Ilaalinta Korantada: Shaqaalaysii aaladaha korantada ku xidha, sida Zener diodes ama varistors, si loo xaddido xadhkaha korantada ee ku meel gaadhka ah iyo ka ilaalinta diode jirka kadeedka xad dhaafka ah.
Xadaynta Hadda: Hirgeli tillaabooyinka xaddidaya hadda, sida fiyuusyada ama wareegyada xaddidan ee hadda jira, si looga hortago qulqulka xad-dhaafka ah ee hadda socda ee diode-ka jirka oo aad ka ilaaliso waxyeelada xad dhaafka ah.
Wareegyada Snubber: Isticmaal wareegyada snubber, oo ka kooban iska caabiyeyaasha iyo capacitors, si aad u baabi'iso tamarta ku kaydsan inductances dulin oo aad u yareyso cadaadiska beddelka ee diode-ka jirka.
Ilaalinta Deegaanka: Ku xidh qaybaha elektiroonigga ah ee xayndaabyada ilaalinta oo shaqaalayso dahaaryo habboon oo habboon si ay uga ilaaliso diode-ka jirka arrimo adag oo deegaanka ah.
Qaybaha Tayada: Isha MOSFET-yada tayada sare leh ee laga helo soosaarayaasha sumcadda leh si loo yareeyo halista cilladaha wax soo saarka ee diode-ka jirka.
Gabagabo
Awoodda MOSFET diode-yaasha jirka, iyadoo inta badan la iska indho tiro, waxay door muhiim ah ka ciyaaraan ilaalinta wareegga iyo waxqabadka. Fahmidda sababaha guud ee guul-darradooda iyo fulinta tallaabooyinka ka-hortagga ayaa muhiim u ah hubinta isku-kalsoonaanta iyo cimri-dhererka nidaamyada elektaroonigga ah. Qaadashada xeeladahan, injineeradu waxay dejin karaan wareegyo adag oo u adkeysan kara xaaladaha adag ee shaqada waxayna yareynayaan khatarta MOSFET diode-ka ee fashilka, ilaalinta hufnaanta qalabka elektiroonigga ah iyo kor u qaadida amniga nidaamka guud.
