Qhov no yog ib qho tseem ceeb rau kev txhim kho tag nrho cov kev ua tau zoo ntawm lub cev thiab txo cov cua kub dissipation.

thermal stability
Kev ntseeg siab ntawm diodes nyob rau hauv qhov chaw kub kub yog qhov tseem ceeb rau kev txiav txim siab. Lub cim tshiab ntawm diodes siv cov ntaub ntawv thermal conductivity kom muaj kev ua tau zoo txawm tias thaum lub sijhawm ua haujlwm kub. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov uas ua haujlwm nyob rau hauv ib puag ncig hnyav xws li tsheb thiab khoom siv.

Kev ntseeg tau ntawm kev xeem
Accelerated Life Test
Kev ntsuas lub neej nrawm yog ib txoj hauv kev siv los ntsuas qhov kev ntseeg tau ntawm diodes. Los ntawm kev sim nyob rau hauv qhov kub thiab txias, high voltage, thiab siab tam sim no tej yam kev mob, manufacturers muaj peev xwm kwv yees lub neej ntawm diodes nyob rau hauv tiag tiag siv ib puag ncig. Qhov kev ntsuam xyuas no tuaj yeem pab txheeb xyuas cov kev ua tsis tau zoo thiab txhim kho tus qauv tsim.

Thermal cycle test
Thermal cycling test simulates thermal stress ntawm diodes hauv qhov chaw ua haujlwm tiag tiag los ntawm kev hloov kub ntau zaus. Qhov kev ntsuam xyuas no tuaj yeem ntsuas qhov kev cia siab thiab ua haujlwm ntev ntawm diodes nyob rau hauv qhov kub thiab txias hloov, kom ntseeg tau tias lawv ua haujlwm ib txwm nyob hauv ntau yam kev mob ib puag ncig.

Mechanical stress test
Kev ntsuam xyuas kev ntxhov siab yog siv los ntsuas kev ua haujlwm ntawm diodes nyob rau hauv kev co thiab tej yam kev mob. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov hauv thaj chaw xws li automotive thiab aerospace, vim tias cov khoom siv no feem ntau ntsib kev nyuaj siab thaum siv.

Kev ua tau zoo ntawm cov tiam tshiab diodes hauv kev siv
Kev siv hauv tsheb fais fab
Txoj kev loj hlob sai ntawm cov tsheb hluav taws xob tau muab cov kev xav tau siab dua rau kev ua haujlwm ntawm diodes. Lub cim tshiab ntawm GaN thiab SiC diodes tau siv dav hauv kev tswj hwm roj teeb thiab lub zog hloov hluav taws xob rau tsheb fais fab. Lawv tsis tsuas yog txhim kho lub zog efficiency ntawm lub cev, tab sis kuj pab txo lub sij hawm them nqi thiab nce ntau.

Daim ntawv thov nyob rau hauv renewable zog
Nyob rau hauv lub zog tauj dua tshiab xws li hnub ci thiab cua zog, diodes yog siv rau kev kho thiab kev hloov pauv. Lub cim tshiab ntawm diodes, nrog lawv cov kev ua haujlwm siab thiab kev ntseeg siab, tuaj yeem ua haujlwm ruaj khov nyob rau hauv ntau yam kev mob ib puag ncig, yog li kev txhim kho tag nrho cov txiaj ntsig thiab kev ntseeg siab ntawm cov tshuab hluav taws xob tauj dua tshiab.

Daim ntawv thov nyob rau hauv industrial automation
Industrial automation systems muaj kev ntseeg siab heev rau diodes. Lub cim tshiab ntawm diodes tau siv rau hauv ntau yam khoom siv automation, nrog rau servo drives, zaus converters, thiab lub cev muaj zog controllers.
