Tiv tauj nrog kev lag luam kho tshuab hluav taws xob txhua tus paub tias IGBT chav tsev yog cov khoom tseem ceeb los tswj cov zis tam sim no thaum lub tsheb hluav taws xob ceev thiab cov lus tawm tam sim no thaum nres zog cov lus. IGBT yog dab tsi? IGBT yog txoj kev luv luv ntawm insulated rooj vag bipolar transistor (IGBT), uas yog muaj BJT (bipolar transistor) thiab MOS (insulated rooj vag cuam tshuam transistor). IGBT muaj qhov zoo ntawm cov tswv yim siab impedance ntawm MOSFET thiab qis conduction voltage poob ntawm GTR. Nws haum rau lub hloov tshuab nrog DC voltage ntawm 600V thiab siab dua, xws li AC lub cev muaj zog, lub inverter, hloov fais fab mov, lub teeb pom kev zoo, tsav lub zog thiab lwm yam teb. Cov ncauj lus ntawm tshooj lus no yog piav qhia cov ntawv thov ntawm laser soldering rau automotive IGBT module.
IGBT module yog modular semiconductor khoom uas yog tsim los ntawm IGBT (insulated rooj vag bipolar transistor nti) thiab FWD (freewheeling diode nti) los ntawm kev tshwj xeeb Circuit Court IGBT module yog ncaj qha thov rau inverter, ce thiab lwm yam khoom siv; IGBT module muaj cov yam ntxwv ntawm kev txuag hluav taws xob, txhim kho yooj yim thiab txij nkawm, ruaj khov cua sov tsis muaj mob, thiab lwm yam.; tam sim no, feem ntau ntawm cov khoom muag hauv kev ua lag luam yog cov khoom lag luam zoo li no, thiab cov dav dav IGBT kuj tseem hais txog IGBT module; nrog kev tshaj tawm ntawm lub tswv yim ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, cov khoom lag luam yuav ntau thiab ntau dua nyob rau hauv kev ua lag luam.
Ua ntej IGBT module tau ntim, IGBT nti thiab lub diode nti yog welded ntawm DBC substrate los ntawm cov cam, thiab tom qab ntawd DBC nrog cov nti tau sib khi, thiab tom qab ntawd cov vuam theem ob yog nqa tawm. Nyob rau hauv txoj kev no, welded sub units tau ntxuav kom tiv thaiv cov sub pawg los ntawm oxidized, thiab tom qab ntawd ces cov koog txuas, electrodes, vuam vuam thiab vuam txuas yog welded rau lub tshav kub dissipation puag phaj ntawm aluminium carbide los ntawm cov cuab yeej siv.
