Insulated Gate Bipolar Transistor Tsim Tswv Yim

Lub tswv yim tsim ntawm Insulated Gate Bipolar Transistor (IGBT) tsom rau kev sib koom ua ke ntawm qhov zoo ntawm lub zog MOSFETs thiab bipolar junction transistors (BJT / GTR) kom kov yeej cov kev txwv ntawm ib qho khoom siv hauv siab -voltage, siab - daim ntawv thov tam sim no.

 

Core Design Concept

Compound Structure, Complementing Strengths thiab Weaknesses
IGBT sib txuas cov input siab impedance, voltage- tsav kev khiav hauj lwm, thiab ceev hloov cov yam ntxwv ntawm MOSFETs nrog rau qhov tsawg conduction voltage poob thiab siab tam sim no ceev tus yam ntxwv ntawm BJTs, tsim ib tug hybrid ntaus ntawv ntawm "voltage tswj + bipolar conduction."

 

Txhim kho kev hloov pauv kev coj ua kom txo qis kev poob qis
Los ntawm txhaj cov neeg nqa khoom tsawg (qhov) mus rau hauv cheeb tsam N⁻ drift, cov kev hloov pauv kev hloov pauv tau txo qis ntawm - lub xeev tsis kam, tso cai rau IGBT kom tswj tau qhov hluav taws xob qis (Vce(sat)) txawm nyob rau hauv high voltage, deb superior rau MOSFETs nrog tib voltage ntsuas.

 

Vertical Plaub- Txheej Txheem (P⁺/N⁻/P/N⁺) Optimizes Voltage Withstand thiab tam sim no muaj peev xwm
Siv cov qauv kev coj ua ntsug, qhov tuab thiab maj mam doped N⁻ drift cheeb tsam bears high voltage thaiv, thaum lub P⁺ collector zoo txhaj cov qhov, ntsuas high voltage withstand thiab loj tam sim no nqa peev xwm.

 

MOS Gate Insulation Control Simplifies Tsav Circuit Court
Lub rooj vag tswj cov channel tsim los ntawm SiO₂ rwb thaiv tsev txheej thiab tuaj yeem tsav los ntawm lub qhov rooj hluav taws xob ib leeg, yuav tsum muaj lub zog tsav tsawg thiab tshem tawm qhov xav tau rau kev txuas ntxiv tam sim no zoo li BJT.

 

Txhawb High Switching Frequency thiab High Power Density
Piv nrog rau thyristors lossis GTOs, IGBTs muaj kev hloov pauv sai dua (txog li pua kHz ntau), thiab nrog kev nce qib thev naus laus zis (xws li xya- tiam micro-trench thiab teb- nres cov qauv), lub zog ntom ntom txuas ntxiv, ua rau lawv tsim nyog rau siab - zog tshiab xws li{4}frequencies tsheb, photovoltaic inverters, thiab industrial variable zaus drives.
