Eqinisweni, kusukela egameni, amandla e-MOSFET ukuthi angaphinde asebenze lapho okukhiphayo kukhulu, ukuhlukaniswa kwe-MOSFET kuhlukaniswe ngezinhlobo eziningi, okuzungeze izici zokusetshenziswa kwamandla singahlukaniswa zibe ngcono kanye nokuncipha kohlobo, uma ngokuhambisana nesiteshi ukukhetha amagama angahlukaniswa ngohlobo lwesiteshi esingu-N kanye nohlobo lwesiteshi esingu-P.
Ama-MOSFET asetshenziswa kakhulu njengokushintshwa kwesistimu kumasistimu akhipha amandla. Uma sengeza enye i-voltage phakathi kwesango nomthombo we-N-channel MOSFET, izovula iswishi yayo yamandla. Uma iswishi yamandla isivuliwe, iswishi yamandla igeleza isuka ku-drain iye emthonjeni. Kukhona ukumelana kwangaphakathi phakathi komsele nomthombo, esiwubiza ngokujwayelekile nge-on-resistor RDS(ON). Kumele kucace ukuthi isango le-MOSFET empeleni liyisiphephelo se-impedance ephezulu, ngakho-ke sidinga ukwengeza enye i-voltage esangweni. Lapho i-voltage phakathi komthombo nesango inguziro, iswishi yamandla iyacisha futhi ukugeleza kwamanje kuyanqamuka ngokuvumelana nedivayisi. Noma idivayisi ivaliwe isikhathi eside, kusekhona inani elincane lamanje, elibizwa ngokuthi i-IDSS yamanje yokuvuza.
NgobaAma-MOSFETzingenye yezingxenye ezibaluleke kakhulu zohlelo lokulawula ugesi, ukukhetha i-MOSFET efanele kudlala indima ebalulekile empumelelweni yalo lonke uhlelo lokuklama. Ngokwazi kuphela izinhlobo zama-MOSFET nezici zawo ezibalulekile, abaklami bangakhetha i-MOSFET elungile yomklamo othile.
I-Power MOSFET iyisigaba esivame ukusetshenziswa kakhulu samadivayisi kagesi, igama eligcwele lamaShayina lithi - ishubhu lomphumela we-metal oxide semiconductor field effect. Kungokwedivayisi yokukhipha amandla, ikakhulukazi eyakhiwe ngensimbi, i-oxide kanye nezinto ze-semiconductor. Pho ayini amandlaI-MOSFET?
Ngokuthuthukiswa kwemakethe okusebenzayo kanye nokuhlanganiswa kwezinsiza ngempumelelo,olukeyisibe enye yama-ejenti avelele futhi akhula ngokushesha e-Asia, futhi kuwumgomo ovamile ka- olukey ukuba i-ejenti ebaluleke kakhulu emhlabeni. Ngokuhamba kweminyaka, inkampani olukey ukusinda ngesikweletu, ukunamathela "ikhwalithi kuqala, isevisi kuqala" inhloso kanye namabhizinisi amaningi zobuchwepheshe obuphezulu ekhaya nakwamanye amazwe, ifektri yasekuqaleni ukusungula ubuhlobo obuhle ukusebenza, iminyaka eminingi yokuhlangenwe nakho kochwepheshe ukusatshalaliswa. , ngesikweletu esihle, isevisi enhle kakhulu, futhi yazuza ukwethenjwa nokusekelwa kabanzi.
