Qhov txawv ntawm IGBT thiab MOSFET

IGBT (Insulated Gate Bipolar Transistor) thiab MOSFET (Hlau-Oxide-Semiconductor Field-Effect Transistor) yog ob qho khoom siv hluav taws xob semiconductor dav siv hauv hluav taws xob hluav taws xob. Txawm hais tias ob qho tib si yog cov khoom tseem ceeb hauv ntau daim ntawv thov, lawv sib txawv hauv ntau yam. Hauv qab no yog qhov sib txawv ntawm IGBT thiab MOSFET:

1. Txoj Cai Ua Haujlwm

- IGBT: IGBT sib txuas cov yam ntxwv ntawm ob qho tib si BJT (Bipolar Junction Transistor) thiab MOSFET, ua rau nws yog ib qho khoom siv sib xyaw. Nws tswj lub hauv paus ntawm BJT los ntawm lub rooj vag voltage ntawm MOSFET, uas nyob rau hauv lem tswj BJT tus conduction thiab txiav tawm. Txawm hais tias qhov kev coj ua thiab kev txiav tawm ntawm IGBT yog qhov nyuaj, nws muaj qhov tsis zoo ntawm cov hluav taws xob tsis zoo thiab kev ua haujlwm siab.

- MOSFET: MOSFET yog ib qho kev cuam tshuam los ntawm transistor uas tswj tam sim no nyob rau hauv ib tug semiconductor los ntawm lub rooj vag voltage. Thaum lub rooj vag voltage tshaj qhov voltage, ib tug conductive txheej ntaub ntawv, tso cai rau tam sim no ntws. Hloov pauv, thaum lub rooj vag voltage qis dua qhov pib, cov txheej txheem hluav taws xob ploj mus, thiab tam sim no tsis tuaj yeem ntws. Kev ua haujlwm ntawm MOSFET yog qhov yooj yim, nrog rau kev hloov ceev ceev.

2. Cov cheeb tsam thov

- IGBT: Vim nws qhov siab voltage kam rau siab, qis conduction voltage poob, thiab ceev hloov kev ua tau zoo, IGBT tshwj xeeb tshaj yog haum rau high-power, tsawg-tso daim ntawv thov xws li inverters, lub cev muaj zog tsav tsheb, vuam tshuab, thiab uninterruptible fais fab mov (UPS) . Hauv cov ntawv thov no, IGBT muaj txiaj ntsig zoo tswj kev ua haujlwm siab-voltage thiab high-tam sim no hloov pauv.

- MOSFET: MOSFET, nrog nws cov lus teb ceev ceev, kev tawm tswv yim siab, kev hloov pauv ruaj khov, thiab tus nqi qis, yog siv dav hauv kev siv hluav taws xob tsawg, hloov pauv ceev xws li cov khoom siv hluav taws xob hloov hluav taws xob, teeb pom kev zoo, lub suab amplifiers, thiab logic circuits. . MOSFET ua tau zoo tshwj xeeb hauv kev siv hluav taws xob tsawg thiab hluav taws xob tsawg.
