Umahluko phakathi kwee-BJT kunye nee-MOSFET kwiiNkqubo zoLawulo lweBattery (BMS)

1. Ii-Bipolar Junction Transistors (BJTs):

(1) Ulwakhiwo:Ii-BJT zizixhobo ze-semiconductor ezinee-electrode ezintathu: isiseko, i-emitter, kunye nomqokeleli. Ngokuqhelekileyo zisetyenziselwa ukukhulisa okanye ukuguqula iimpawu. I-BJTs zifuna igalelo elincinci langoku kwisiseko sokulawula ukuhamba kwangoku okukhulu phakathi komqokeleli kunye ne-emitter.

(2) Umsebenzi kwi-BMS: In BMSizicelo, ii-BJT zisetyenziselwa ulwando lwangoku lwangoku. Bancedisa ukulawula nokulawula ukuhamba kwangoku ngaphakathi kwenkqubo, ukuqinisekisa ukuba iibhetri zihlawuliswa kwaye zikhutshwe ngokufanelekileyo nangokukhuselekileyo.

(3) Iimpawu:Ii-BJT zinenzuzo ephezulu yangoku kwaye zisebenza kakhulu kwizicelo ezifuna ulawulo oluchanekileyo lwangoku. Ngokuqhelekileyo banovakalelo oluthe kratya kwiimeko zobushushu kwaye banokuchaphazeleka kukuchithwa kwamandla aphezulu xa kuthelekiswa neeMOSFET.

2. I-Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs):

(1) Ulwakhiwo:Ii-MOSFET zizixhobo zesemiconductor ezineetheminali ezintathu: isango, umthombo, kunye nedreyini. Basebenzisa i-voltage ukulawula ukuhamba kwangoku phakathi komthombo kunye ne-drain, ibenza basebenze kakhulu ekutshintsheni izicelo.

(2) Umsebenzi kwiBMS:Kwizicelo ze-BMS, ii-MOSFETs zihlala zisetyenziselwa amandla azo okutshintsha okusebenzayo. Bangakwazi ukuvula ngokukhawuleza kunye nokucima, ukulawula ukuhamba kwangoku kunye nokuchasana okuncinci kunye nokulahlekelwa kwamandla. Oku kubenza balungele ukukhusela iibhetri ekutshajisweni, ukukhupha ngaphezulu, kunye neesekethe ezimfutshane.

(3) Iimpawu:Ii-MOSFETs zine-impedance ephezulu yokufaka kunye nokunganyangeki okuphantsi, nto leyo eyenza ukuba zisebenze kakuhle ngokulahla ubushushu obuphantsi xa kuthelekiswa nee-BJTs. Zifaneleke ngokukodwa kwi-high-speed kunye ne-high-efficiency switching applications ngaphakathi kwe-BMS.

Isishwankathelo:

• BJTszingcono kwizicelo ezifuna ulawulo lwangoku oluchanekileyo ngenxa yenzuzo ephezulu yangoku.
• Ii-MOSFETszikhethwa ukutshintshwa okusebenzayo kunye nokukhawulezayo kunye nokulahla ubushushu obuphantsi, kubenze balungele ukukhusela nokulawula ukusebenza kwebhetriBMS.
