Isekethe yokuvikela i-overcurrent ye-MOSFET ukuze kugwenywe izingozi zokushabalalisa ugesi

Ukunikezwa kwamandla njengezingxenye zokusabalalisa imishini ye-elekthronikhi, ngaphezu kwezici zokucabangela izinhlinzeko zemishini yesistimu yokuphakelwa kwamandla, izinyathelo zayo zokuzivikela nazo ziningi kakhulu.kubalulekile, njengokusebenza ngokweqile kwamanje, amandla kagesi amaningi, ukugcinwa kwezinga lokushisa elingaphezu kwamandla. Uma ukunikezwa kwamandla kungenalo uhlelo lokuklama ukuvikela okudlulele, ekuphumeni kokwehluleka kwesekethe emfishane noma ukulayishwa ngokweqile kuzodala umonakalo ekunikezeni amandla, kodwa futhi okungenzeka kakhulu kubangele imbangela eyengeziwe.ukubhujiswa okokusebenza kwe-elekthronikhi, futhi kubangele ngisho nokusebenza kwangempela kwabasebenzi bengozi ye-electrocution kanye nezingozi zomlilo nezinye zokuphepha, kanye nokuvikela okudlulele kokuphakelwa kukagesi ngokusetshenziswaAma-MOSFET ezihlobene.

MOSFET Driver Circuit Izidingo

Ukukubeka ngokungagwegwesi ukuvikelwa kwe-overcurrent, itholakala ekuphumeni kwamaphutha esekethe emfishane noma ukulayishwa ngokweqile kwamandla kagesi noma ukugcinwa komthwalo, kulesi sigaba sokuvikeleka kokuphakelwa kwamandla okudlulele kunezindlela ezihlukahlukene, njengokuphuma okuqhubekayo, okuqhubekayo. uhlobo lwamandla, njll., kodwa ukuthuthukiswa kwesekethe enjalo yokuvikela okweqile akukwazi ukuhlukaniswa ne-MOSFET, ama-MOSFET ekhwalithi ephezulu angathuthukisa indima yokuvikela amandla okudlulele.

Isifunda sokuvikela esidlulele se-MOSFET ukuze kugwenywe izingozi zokuphelelwa amandla kwamandla(1)
