Umehluko Phakathi kwama-BJT nama-MOSFET kuzinhlelo zokuphatha ibhethri (i-BMS)

1. Ama-Transistors e-Bipolar Junction (ama-BJT):

(1) Isakhiwo:Ama-BJT angamadivayisi e-semiconductor anama-electrode amathathu: isisekelo, i-emitter, kanye ne-collector. Asetshenziswa kakhulu ekukhuliseni noma ekushintsheni amasignali. Ama-BJT adinga ugesi omncane wokufaka esisekelweni ukulawula ukugeleza kogesi okukhulu phakathi kwe-collector kanye ne-emitter.

(2) Umsebenzi ku-BMS: In I-BMSNgezinhlelo zokusebenza, ama-BJT asetshenziselwa amakhono awo okukhulisa amandla amanje. Asiza ekuphatheni nasekulawuleni ukugeleza kwamandla ngaphakathi kwesistimu, ukuqinisekisa ukuthi amabhethri ayashajwa futhi akhishwa kahle nangokuphephile.

(3) Izici:Ama-BJT anamandla aphezulu okusebenza futhi asebenza kahle kakhulu ekusetshenzisweni okudinga ukulawulwa kwamanje okunembile. Ngokuvamile azwela kakhulu ezimweni zokushisa futhi angahlupheka ngokushabalaliswa kwamandla aphezulu uma kuqhathaniswa nama-MOSFET.

2. Ama-Transistors Omphumela Wensimu Yensimbi-I-Oxide-Semiconductor (ama-MOSFET):

(1) Isakhiwo:Ama-MOSFET angamadivayisi e-semiconductor anama-terminal amathathu: isango, umthombo, kanye ne-drain. Asebenzisa i-voltage ukulawula ukuhamba kombane phakathi komthombo kanye ne-drain, okwenza asebenze kahle kakhulu ekushintsheni izinhlelo zokusebenza.

(2) Umsebenzi kuI-BMS:Kuzinhlelo zokusebenza ze-BMS, ama-MOSFET avame ukusetshenziswa ngenxa yamakhono awo okushintsha asebenza kahle. Angavula futhi avale ngokushesha, alawule ukugeleza kwamandla kagesi ngokumelana okuncane kanye nokulahlekelwa amandla. Lokhu kuwenza abe mahle kakhulu ekuvikeleni amabhethri ekushajeni ngokweqile, ekukhipheni ngokweqile, kanye nasezindaweni ezimfushane.

(3) Izici:Ama-MOSFET anokuvinjelwa okuphezulu kokufaka kanye nokumelana okuncane, okwenza asebenze kahle kakhulu ngokushisa okuphansi uma kuqhathaniswa nama-BJT. Afaneleka kakhulu ezinhlelweni zokushintsha ezisheshayo nezisebenza kahle kakhulu ngaphakathi kwe-BMS.

Isifinyezo:

• Ama-BJTzingcono kakhulu ezinhlelweni zokusebenza ezidinga ukulawulwa kwamanje okunembile ngenxa yokwanda kwawo kwamanje okuphezulu.
• Ama-MOSFETzikhethwa kakhulu ekushintsheni okusebenzayo nokusheshayo kanye nokushabalalisa ukushisa okuncane, okwenza zibe zilungele ukuvikela nokuphatha ukusebenza kwebhethri kuI-BMS.
