Xaiv ibtuab tooj liab hwj chim boardraws li cov kev xav tau tam sim no thiab kub dissipation. Qhov siab dua qhov tam sim no thiab qhov kub dissipation tsis zoo, qhov tuab ntawm cov tooj liab yuav tsum yog.
Tam sim no yog thawj qhov taw qhia. Kev kwv yees yooj yim: Ib qho 1 hli dav hlau nrog 1oz tooj liab tuab (35 μ m) muaj kev nyab xeeb tam sim no nqa peev xwm ntawm 1.5A; 2oz (70 μm) tuaj yeem ncav cuag 2.5A. Hauv cov xwm txheej tam sim no siab xws li cov khoom siv hluav taws xob, 3oz lossis cov xov hlau tuab yog feem ntau siv. Yog tias tsim ib qho tam sim no ntawm 100A, txawm tias 40oz tooj liab thickness yuav tsum tau.
Thaum tshav kub kub dissipation yog lwm yam tseem ceeb. Qhov tuab ntawm tooj liab, qhov ceev ntawm thermal conductivity. Lub tshav kub dissipation efficiency ntawm 2oz tooj liab phaj tuaj yeem txhim kho los ntawm 60% piv rau 1oz. Nyob rau hauv siab -cov khoom siv fais fab xws li IGBTs, cov tooj liab tuab tuaj yeem ua kom sov sai sai, tsis txhob muaj cua sov hauv zos.
Thaum xaiv qhov ua tau zoo, tsis txhob ua qhov muag tsis pom qhov tuab tshaj . 3-6 oz yog qhov tseem ceeb hauv kev lag luam, thiab tshaj 15 oz yuav ua rau muaj teeb meem kev ua haujlwm. Txoj kev tsim qauv kuj tseem ceeb heev kom tsis txhob nqaim tam sim ntawd. Nws raug nquahu kom nteg tooj liab thiab ntxiv cov cua sov tawm ntawm cov khoom siv hluav taws xob hauv qab siab -.
Nqe siv: Rau kev xaiv tshwj xeeb, nws raug nquahu kom sab laj nrog cov chaw tsim khoom (Uniwell circuits) rau cov lus qhia tshaj lij raws li koj qhov loj me tam sim no thiab cov cua sov dissipation.
