Umahluko Phakathi kwee-BJT kunye nee-MOSFET kwiiNkqubo zoLawulo lweBhetri (ii-BMS)

1. IiTransistors zeBipolar Junction (ii-BJT):

(1) Ulwakhiwo:Ii-BJT zizixhobo ze-semiconductor ezinee-electrode ezintathu: isiseko, i-emitter, kunye ne-collector. Zisetyenziselwa ikakhulu ukukhulisa okanye ukutshintsha imiqondiso. Ii-BJT zifuna umsinga omncinci wokufaka kwisiseko ukulawula ukuhamba komsinga omkhulu phakathi kwe-collector kunye ne-emitter.

(2) Umsebenzi kwi-BMS: In I-BMSKwii-applications, ii-BJT zisetyenziselwa amandla azo okukhulisa amandla. Zinceda ekulawuleni nasekulawuleni ukuhamba kwamandla ngaphakathi kwenkqubo, ukuqinisekisa ukuba iibhetri zitshajwa kwaye zikhutshwa ngokufanelekileyo nangokukhuselekileyo.

(3) Iimpawu:Ii-BJT zinamandla aphezulu ombane kwaye zisebenza kakuhle kakhulu kwizicelo ezifuna ulawulo oluchanekileyo lwamandla ombane. Ngokuqhelekileyo zinobuthathaka ngakumbi kwiimeko zobushushu kwaye zinokuchaphazeleka kukuchithwa kwamandla okuphezulu xa kuthelekiswa nee-MOSFET.

2. Iitransistor ze-Field-Effect Transistors zeMetal-Oxide-Semiconductor (iiMOSFET):

(1) Ulwakhiwo:IiMOSFET zizixhobo ze-semiconductor ezinee-terminals ezintathu: isango, umthombo, kunye nomsele. Zisebenzisa i-voltage ukulawula ukuhamba kombane phakathi komthombo nomsele, nto leyo ezenza zibe nempumelelo enkulu ekutshintsheni.

(2) Umsebenzi kwiI-BMS:Kwizicelo ze-BMS, ii-MOSFET zihlala zisetyenziswa ngenxa yezakhono zazo zokutshintsha ezisebenza kakuhle. Zinokuvula nokucima ngokukhawuleza, zilawula ukuhamba kombane ngokumelana okuncinci kunye nokulahleka kwamandla. Oku kuzenza zilungele ukukhusela iibhetri ekutshajisweni kakhulu, ekukhutshweni kakhulu, nakwiisekethe ezimfutshane.

(3) Iimpawu:IiMOSFET zinoxinzelelo olukhulu lokufaka kwaye azixhathisi kakhulu, nto leyo eyenza ukuba zisebenze kakuhle kwaye azichithi ubushushu kakhulu xa kuthelekiswa neeBJT. Zifanelekile ngokukodwa kwizicelo zokutshintsha ezikhawulezayo nezisebenza kakuhle ngaphakathi kweBMS.

Isishwankathelo:

• Ii-BJTzingcono kwizicelo ezifuna ulawulo oluchanekileyo lwamandla ngenxa yokuba amandla azo aphezulu.
• IiMOSFETZikhethwa xa zitshintsha ngokukhawuleza nangokusebenzayo, zikwazi ukucima ubushushu kancinci, nto leyo ezenza zibe zilungele ukukhusela nokulawula ukusebenza kwebhetri.I-BMS.
