Fais fab mov tsis muaj voltage tso zis teeb meem
Lub zog hloov hluav taws xob ntawm lub tshuab hluav taws xob feem ntau ua rau ob qhov hluav taws xob, 18V thiab 5V, ntawm qhov uas 5V muab lub zog rau lub ntsiab tswj nti thiab qhov tseem ceeb zaub tsav nti, thiab 18V muab lub zog rau kiv cua thiab IGBT tsav Circuit Court. Vim tias lub zog siv hluav taws xob ntawm kev tswj Circuit Court ntawm induction cooker yog me me, hloov cov khoom siv hluav taws xob feem ntau siv cov chips tsav tsheb nrog on-chip integrated switching hlab. Txhawm rau kom txuag tau cov nqi, ntau lub zog siv hluav taws xob kuj siv cov tsav tsheb tsis sib cais. Feem ntau siv tsav nti qauv yog VIPer12A, thiab lwm yam.
Lub hauv paus ntsiab lus ua haujlwm ntawm induction cooker hloov hluav taws xob
Qhov tsis sib xws ntawm cov khoom siv hauv cov khoom siv hluav taws xob hloov pauv cov khoom siv hluav taws xob nrog cov chips sib txawv thiab cov kev daws teeb meem yuav txawv me ntsis, tab sis lawv cov qauv kev ua haujlwm yooj yim yog tib yam. Siv VIPer12A ua piv txwv, uas yog tus qauv siv ntau heev hauv induction cookers. VIPer12A yog lub zog tsav nti tawm los ntawm STMicroelectronics. Lub nti ua ke nrog lub zog hluav taws xob siab siab thiab qhov hluav taws xob qhov hluav taws xob tau muab tso rau hauv qhov ntws ntawm lub nti hloov raj, yog li cov khoom siv hluav taws xob tuaj yeem ua haujlwm yam tsis muaj qhov pib tawm tsam. Cov nti kuj tseem muaj kev sib xyaw nrog kub dhau, dhau-tam sim no, dhau-voltage thiab lwm yam kev tiv thaiv circuits. Raws li cov pob khoom sib txawv, nws lub zog tso zis siab tshaj plaws tuaj yeem ncav cuag 13W.
Ntxiv rau qhov tsim hluav taws xob sab hauv hluav taws xob ntawm VIPer12A, nws lub hwj chim raj qauv kuj tseem tshwj xeeb heev. Lub raj hloov sab hauv muaj ob qhov chaw, thiab thaj chaw ntawm ob lub hauv paus ntsiab lus sib txawv, thiab cov qauv ntsuas tam sim no txuas nrog ntawm qhov chaw nrog thaj tsam me me thiab hauv av. Txij li thaum tus qauv resistor txuas nrog lub hauv paus nrog thaj tsam me me, qhov tam sim no ntws los ntawm qhov resistor tsis yog tag nrho cov tam sim no ntws los ntawm lub raj hloov, tab sis ib feem ntawm nws, thiab tag nrho cov tam sim no tuaj yeem tau los ntawm kev xam proportional. Qhov kev tsim no tsis tsuas yog txo qhov poob ntawm cov qauv resistor, tab sis kuj muaj qee yam kev txuag hluav taws xob, thiab tsis tas yuav tsum muaj cov qauv ntsuas tam sim no sab nraum lub nti, uas yooj yim rau cov qauv hauv Circuit Court thiab txuag nqi. Qhov no kuj yog ib qho tshwj xeeb nam ntawm no chip tsim.
