Qhov Sib Txawv Ntawm BJTs thiab MOSFETs hauv Cov Txheej Txheem Tswj Xyuas Roj Teeb (BMS)

1. Cov Transistors Bipolar Junction (BJTs):

(1) Cov Qauv:BJTs yog cov khoom siv semiconductor nrog peb lub electrodes: lub hauv paus, emitter, thiab collector. Lawv feem ntau yog siv rau kev ua kom nrov lossis hloov cov teeb liab. BJTs xav tau qhov tam sim no me me rau lub hauv paus kom tswj tau qhov tam sim no loj dua ntawm tus collector thiab emitter.

(2) Kev Ua Haujlwm hauv BMS: In BMScov ntawv thov, BJTs yog siv rau lawv cov peev xwm ua kom muaj zog tam sim no. Lawv pab tswj thiab tswj cov dej ntws tam sim no hauv lub kaw lus, xyuas kom meej tias cov roj teeb tau them thiab tso tawm kom zoo thiab muaj kev nyab xeeb.

(3) Cov yam ntxwv:BJTs muaj qhov nce siab tam sim no thiab zoo heev rau cov ntawv thov uas xav tau kev tswj tam sim no kom meej. Lawv feem ntau rhiab heev rau cov xwm txheej thermal thiab tuaj yeem raug kev txom nyem los ntawm kev siv hluav taws xob ntau dua piv rau MOSFETs.

2. Cov Hlau-Oxide-Semiconductor Field-Effect Transistors (MOSFETs):

(1) Cov Qauv:MOSFETs yog cov khoom siv semiconductor uas muaj peb lub qhov kawg: lub rooj vag, qhov chaw, thiab qhov dej ntws. Lawv siv hluav taws xob los tswj cov dej ntws ntawm qhov chaw thiab qhov dej ntws, ua rau lawv ua haujlwm tau zoo heev hauv kev hloov pauv.

(2) Kev ua haujlwm hauvBMS:Hauv cov ntawv thov BMS, MOSFETs feem ntau siv rau lawv cov peev xwm hloov pauv zoo. Lawv tuaj yeem qhib thiab kaw sai sai, tswj cov dej ntws nrog qhov tsis kam tsawg thiab poob hluav taws xob. Qhov no ua rau lawv zoo tagnrho rau kev tiv thaiv cov roj teeb los ntawm kev them ntau dhau, kev tso tawm ntau dhau, thiab luv luv circuits.

(3) Cov yam ntxwv:MOSFETs muaj cov input impedance siab thiab qis on-resistance, ua rau lawv ua haujlwm tau zoo nrog cov cua sov tsawg dua piv rau BJTs. Lawv yog cov tsim tshwj xeeb rau kev siv high-speed thiab high-efficiency switching hauv BMS.

Kev Txheeb Xyuas:

• Cov BJTzoo dua rau cov ntawv thov uas xav tau kev tswj hwm tam sim no vim lawv qhov nce siab tam sim no.
• MOSFETsyog qhov zoo dua rau kev hloov pauv zoo thiab ceev nrog kev tso cua sov qis dua, ua rau lawv zoo tagnrho rau kev tiv thaiv thiab tswj kev ua haujlwm roj teeb hauvBMS.
