Kev siv MOSFET hauv photovoltaic inverters

Ua hauj lwm hauv paus ntsiab lus ntawm photovoltaic inverter
Photovoltaic inverter yog ib qho khoom siv uas hloov cov khoom siv hluav taws xob ncaj qha los ntawm cov hlwb photovoltaic mus rau qhov hloov pauv tam sim no, thiab yog lub hauv paus tseem ceeb ntawm kev tsim hluav taws xob photovoltaic. Photovoltaic panels hloov lub hnub ci zog rau hauv qhov tam sim no ncaj qha, thaum cov khoom siv hauv tsev thiab kev lag luam feem ntau siv hloov pauv tam sim no, yog li yuav tsum siv cov inverter kom tiav cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob. Photovoltaic inverters tsis tsuas yog yuav tsum tau siv zog hloov hluav taws xob zoo xwb, tab sis kuj tseem muab cov hluav taws xob ruaj khov thaum cov kab hluav taws xob tsis ruaj khov.

Daim ntawv thov ntawm MOSFET hauv Photovoltaic Inverters
Lub zog hloov pauv module
Nyob rau hauv lub zog hloov dua siab tshiab module ntawm photovoltaic inverters, MOSFETs yog dav siv nyob rau hauv lub ntsiab Circuit Court ntawm lub inverter. Vim yog MOSFET qhov hloov pauv ceev ceev thiab tsis tshua muaj kev tiv thaiv, nws tuaj yeem ua haujlwm ntawm cov zaus siab, yog li txo qis zog thiab txhim kho qhov ua tau zoo ntawm inverter.

DC / DC converter
Hauv qee lub tshuab hluav taws xob photovoltaic, DC / DC converters yog siv los hloov DC lub zog ntawm cov qib sib txawv rau hauv qhov hluav taws xob tsim nyog rau cov tswv yim inverter. MOSFETs ua lub luag haujlwm tseem ceeb hauv cov hloov pauv no, txhim kho kev hloov pauv tau zoo thiab txo qis zog.

tiv thaiv Circuit Court
MOSFET kuj tseem siv rau hauv kev tiv thaiv Circuit Court ntawm photovoltaic inverters, xws li overvoltage, overcurrent, thiab luv-circuit tiv thaiv. Los ntawm kev tswj hwm kev hloov pauv ntawm MOSFETs, nws muaj peev xwm tiv thaiv kev puas tsuaj rau photovoltaic inverters nyob rau hauv cov xwm txheej txawv txav thiab txuas ntxiv lawv lub neej kev pab cuam.

Qhov zoo ntawm MOSFET hauv photovoltaic inverters
Kev hloov hluav taws xob zoo
MOSFETs muaj qhov tsis kam tiv thaiv thiab siab hloov ceev, uas ua rau lawv tswj tsis tau lub zog poob thaum lub zog hloov pauv, yog li txhim kho tag nrho cov txiaj ntsig ntawm photovoltaic inverters. Nrog rau kev txhim kho ntawm cov tshuab photovoltaic mus rau lub zog siab thiab kev ua haujlwm zoo, tus yam ntxwv ntawm MOSFET ua qhov tseem ceeb tshwj xeeb.

Muaj peev xwm ua haujlwm siab
Niaj hnub nimno photovoltaic inverters feem ntau yuav tsum tau ua haujlwm nyob rau hauv high-frequency tej yam kev mob kom txo tau qhov loj thiab hnyav ntawm transformers thaum txhim kho lub zog dynamic teb muaj peev xwm. MOSFETs tuaj yeem ua haujlwm tau zoo ntawm ntau zaus, ua rau inverter tsim ntau dua thiab hnav.

Kev ntseeg tau thiab lub neej ntev
Cov yam ntxwv ntawm MOSFETs ua rau muaj cua sov tsawg dua thaum lub sijhawm ua haujlwm, yog li txo kev cia siab ntawm cov khoom siv hluav taws xob. Kev ua haujlwm qis qis tsis tsuas yog txhim kho kev ruaj ntseg ntawm cov cuab yeej siv, tab sis kuj tseem txuas ntxiv lub neej kev pab cuam ntawm lub inverter.

Kev sib tw thiab kev txhim kho yav tom ntej
Kev tswj cua sov
Txawm hais tias MOSFETs tsis tshua muaj kev tiv thaiv, cov cua sov dissipation tseem yog ib qho teeb meem uas yuav tsum tau daws thaum lub sij hawm ua haujlwm siab thiab ua haujlwm siab. Kev tswj xyuas hluav taws xob zoo thiab kev tsim hluav taws xob zoo yog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm MOSFETs.

kev tswj tus nqi
Vim muaj kev siv ntau ntxiv ntawm MOSFETs hauv photovoltaic inverters, lawv cov nqi teeb meem kuj tau txais kev nyiam ntau. Yuav ua li cas tswj cov nqi thaum ua kom ntseeg tau tias kev ua tau zoo yog qhov kev sib tw tam sim no los ntawm photovoltaic inverter manufacturers.

Kev kawm txuj ci thiab cov khoom siv tshiab
Nrog rau kev nce qib ntawm cov ntaub ntawv kev tshawb fawb, kev qhia txog cov ntaub ntawv tshiab tuaj yeem txhim kho kev ua tau zoo ntawm MOSFETs, xws li txo qis kev tiv thaiv thiab nce kev hloov ceev. Nyob rau hauv lub neej yav tom ntej, nrog rau kev siv cov ntaub ntawv tshiab xws li silicon carbide (SiC) thiab gallium nitride (GaN), daim ntawv thov kev cia siab ntawm MOSFETs yuav dav dua.
