Kusiyana Pakati pa BJTs ndi MOSFETs mu Battery Management Systems (BMS)

1. Ma Transistors a Bipolar Junction (BJTs):

(1) Kapangidwe:Ma BJT ndi zida za semiconductor zokhala ndi ma electrode atatu: base, emitter, ndi collector. Amagwiritsidwa ntchito makamaka pakukulitsa kapena kusintha ma signali. Ma BJT amafuna mphamvu yaying'ono yolowera ku base kuti azitha kuyendetsa bwino mphamvu pakati pa collector ndi emitter.

(2) Ntchito mu BMS: In BMSPogwiritsa ntchito mapulogalamu, ma BJT amagwiritsidwa ntchito chifukwa cha luso lawo lamakono lokulitsa mphamvu. Amathandiza kuyang'anira ndikuwongolera kayendedwe ka mphamvu mkati mwa dongosolo, kuonetsetsa kuti mabatire akuchajidwa ndi kutulutsidwa bwino komanso mosamala.

(3) Makhalidwe:Ma BJT ali ndi mphamvu zambiri zamagetsi ndipo amagwira ntchito bwino kwambiri pakugwiritsa ntchito magetsi omwe amafunikira mphamvu yeniyeni yowongolera magetsi. Nthawi zambiri amakhala omasuka kwambiri ndi kutentha ndipo amatha kuvutika ndi kutayika kwa mphamvu zambiri poyerekeza ndi ma MOSFET.

2. Ma Transistors a Field-Effect a Metal-Oxide-Semiconductor (MOSFET):

(1) Kapangidwe:Ma MOSFET ndi zida za semiconductor zokhala ndi ma terminal atatu: chipata, gwero, ndi drain. Amagwiritsa ntchito voltage kuti azitha kuyendetsa bwino kayendedwe ka mphamvu pakati pa gwero ndi drain, zomwe zimapangitsa kuti azigwira ntchito bwino kwambiri posinthana.

(2) Ntchito muBMS:Mu ntchito za BMS, ma MOSFET nthawi zambiri amagwiritsidwa ntchito chifukwa cha luso lawo losintha bwino. Amatha kuyatsa ndi kuzimitsa mwachangu, kuwongolera kuyenda kwa magetsi popanda kukana kwambiri komanso kutaya mphamvu. Izi zimapangitsa kuti akhale abwino kwambiri poteteza mabatire ku mphamvu yochulukirapo, kutayikira kwambiri, komanso ma short circuits.

(3) Makhalidwe:Ma MOSFET ali ndi kukana kwakukulu kwa ma input komanso kukana kochepa, zomwe zimapangitsa kuti azigwira ntchito bwino kwambiri komanso kutentha kochepa poyerekeza ndi ma BJT. Ndi oyenera kwambiri kugwiritsa ntchito ma switching othamanga kwambiri komanso ogwira ntchito bwino mkati mwa BMS.

Chidule:

• Ma BJTndi abwino kwambiri pa mapulogalamu omwe amafuna kuwongolera bwino kwa magetsi chifukwa cha kuchuluka kwa magetsi omwe amalowa.
• Ma MOSFETAmakondedwa chifukwa cha kusinthana bwino komanso mwachangu komanso kutentha pang'ono, zomwe zimapangitsa kuti akhale abwino kwambiri poteteza ndikuwongolera magwiridwe antchito a batri.BMS.
