UkunciphaI-MOSFET, eyaziwa nangokuthi ukuncipha kwe-MOSFET, isimo esibalulekile sokusebenza samashubhu womphumela wensimu. Okulandelayo incazelo eningiliziwe yayo:
Izincazelo kanye Nezimpawu
INCAZELO: UkunciphaI-MOSFETwuhlobo olukhethekile lweI-MOSFETekwazi ukuqhuba ugesi ngoba abathwali sebevele bekhona esiteshini sawo lapho i-voltage yesango inguziro noma ingaphakathi kwebanga elithile. Lokhu kuphambene nokuthuthukisaAma-MOSFETokudinga inani elithile le-voltage yesango ukuze kwakhiwe isiteshi sokuqhuba.
Izici: Uhlobo lokunciphaI-MOSFETinezinzuzo ze-impedance ephezulu yokufaka, ukuvuza okuphansi kwamanje kanye ne-impedance yokushintsha ephansi. Lezi zici ziyenza ibe yigugu ezinhlobonhlobo zezinhlelo zokusebenza ekwakhiweni kwesekethe.
Isimiso Sokusebenza
Umgomo wokusebenza wokunciphisaAma-MOSFETingalawulwa ngokushintsha i-voltage yesango ukulawula inani labathwali esiteshini futhi ngaleyo ndlela yamanje. Inqubo yokusebenza ingafinyezwa ngezigaba ezilandelayo:
Isimo esingavunyelwe: Uma i-voltage yesango ingaphansi kwe-voltage ebalulekile phakathi kwesiteshi nomthombo, idivayisi isesimweni esenqatshelwe futhi akukho okwamanje okudlulaI-MOSFET.
Isimo sokuphikisa esingesihle: Njengoba i-voltage yesango ikhula, inkokhelo iqala ukwakha esiteshini, idala umphumela omubi wokumelana. Ngokulungisa i-voltage yesango, amandla okumelana okungalungile angalawulwa, ngaleyo ndlela alawule okwamanje esiteshini.
EMBUSWENI: Lapho i-voltage yesango iqhubeka nokukhuphuka idlula i-voltage ebalulekile,i-MOSFETingena esimweni se-ON kanye nenani elikhulu lama-electron kanye nezimbobo zithuthwa ngesiteshi, okwenza okwamanje okuphawulekayo.
Ukugcwaliswa kwesikhala: Esimeni, i-current esiteshini ifinyelela izinga lokugcwala, lapho ukuqhubeka nokwandisa i-voltage yesango akusakhulisi kakhulu okwamanje.
Isimo sokunqunywa(Qaphela: incazelo "yesimo sokunqamuka" lapha ingase yehluke kancane kwezinye izincwadi ngenxa yokunciphaAma-MOSFETnjalo ziphatha ngaphansi kwezimo ezithile): Ngaphansi kwezimo ezithile (isb, uguquko oludlulele ku-voltage yesango), ukunciphaI-MOSFETingase ingene esimweni sokuqhuba okuphansi, kodwa ayinqamuki ngokuphelele.
Izindawo Zokufaka Isicelo
Uhlobo lokunciphaAma-MOSFETzinezinhlobonhlobo zezinhlelo zokusebenza emikhakheni eminingana ngenxa yezici zazo ezihlukile zokusebenza:
Ukuphathwa kwamandla: Isebenzisa i-impedance yayo ephezulu yokufaka kanye nezici zamanje zokuvuza okuphansi ukuze kuzuzwe ukuguqulwa kwamandla okusebenzayo kumasekhethi okuphatha amandla.
Amasekhethi e-analog nedijithali: dlala indima ebalulekile kumasekhethi e-analog nedijithali njengama-switching elements noma imithombo yamanje.
Ukushayela imoto: Ukulawulwa okunembile kwejubane lemoto nesiteringi kubonakala ngokulawula ukuqhutshwa nokunqanyulwa kweAma-MOSFET.
Inverter Circuit: Ezinhlelweni zokuphehla amandla elanga kanye nezinhlelo zokuxhumana ngomsakazo, njengenye yezingxenye ezibalulekile ze-inverter, ukufeza ukuguqulwa kwe-DC ibe yi-AC.
Isilawuli samandla kagesi: Ngokulungisa usayizi we-voltage ephumayo, ibona ukuphuma okuzinzile kwe-voltage futhi iqinisekisa umsebenzi ojwayelekile wemishini kagesi.
i-caveat
Ekusetshenzisweni okusebenzayo, kuyadingeka ukukhetha ukuncipha okufaneleI-MOSFETimodeli kanye nemingcele ngokwezidingo ezithile.
Kusukela uhlobo lokunciphaAma-MOSFETsebenza ngokuhlukile kuhlobo lokuthuthukisaAma-MOSFET, zidinga ukunakwa okukhethekile ekwakhiweni kwesekethe nokwenza kahle.
Ngamafuphi, uhlobo lokunciphaI-MOSFET, njengengxenye ye-elekthronikhi ebalulekile, inohlu olubanzi lwamathemba ohlelo lokusebenza emkhakheni wezogesi. Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe kanye nokwanda kwesidingo sohlelo lokusebenza, ukusebenza kwayo kanye nobubanzi bokusebenza kwayo nakho kuzoqhubeka nokukhula nokuba ngcono.
