Yuav ua li cas siv cov zis ntawm switching fais fab mov nyob rau hauv parallel
Hloov fais fab mov yog ib hom khoom siv hluav taws xob siv dav hauv ntau yam khoom siv hluav taws xob, suav nrog DC hloov hluav taws xob thiab AC hloov hluav taws xob. Hloov cov khoom siv hluav taws xob tuaj yeem muab qhov ruaj khov, txhim khu kev qha thiab muaj txiaj ntsig zoo thiab cov zis tam sim no, ua rau nws yog thawj qhov kev xaiv rau ntau yam khoom siv hluav taws xob. Txawm li cas los xij, qee zaum, ib qho kev hloov pauv hluav taws xob tso tawm tsis tuaj yeem ua tau raws li qhov xav tau, yog li nws yuav tsum tau siv ntau lub zog hloov hluav taws xob tso tawm ua ke. Nyob rau hauv daim ntawv no, peb yuav qhia nyob rau hauv kom meej yuav ua li cas siv cov zis ntawm switching zog mov nyob rau hauv parallel.
1. Lub hauv paus ntsiab lus ntawm kev sib txuas ua ke
Cov zis ntau tshaj ntawm cov khoom siv hluav taws xob hloov hluav taws xob txuas nrog rau tib lub sijhawm, kom lawv tuaj yeem ua ke rau hauv lar tso zis hluav taws xob. Lub hauv paus ntsiab lus ntawm kev sib txuas ntawm cov khoom siv hluav taws xob yog qhov yooj yim: txuas tag nrho cov ncej zoo ntawm cov khoom siv hluav taws xob thiab txuas tag nrho cov ncej tsis zoo ntawm cov khoom siv hluav taws xob. Ua li no tuaj yeem koom tes nrog txhua qhov chaw siv hluav taws xob thiab sib koom ua ke tso tawm ntau dua tam sim no thiab qhov hluav taws xob. Ntau yam khoom siv hluav taws xob txuas nrog rau qhov sib luag, txhua tus uas tawm tib qhov voltage thiab tam sim no. Yog tias tus naj npawb ntawm cov khoom siv hluav taws xob tso tawm nyob rau hauv qhov sib npaug loj dua, lub zog tso zis yuav loj dua.
2. Lub sijhawm tsim nyog rau cov khoom siv hluav taws xob sib txuas.
Cov zis ntawm ntau yam khoom siv hluav taws xob hloov hluav taws xob sib txuas ua ke tuaj yeem siv rau ntau yam khoom siv hluav taws xob, xws li lub zog hluav taws xob LED teeb pom kev zoo, kev tsav tsheb ceev ceev, zaus converters thiab lwm yam. Hauv cov ntawv thov no, cov zis hluav taws xob lossis tam sim no ntawm ib qho kev hloov hluav taws xob tsis tuaj yeem ua tau raws li qhov xav tau. Kev sib txuas ntau yam khoom siv hluav taws xob hloov mus rau qhov sib npaug tuaj yeem ua rau lub zog tso zis ntau ntxiv thiab ua tau raws li daim ntawv thov kev xav tau ntawm lub zog siab, siab voltage thiab siab tam sim no.
3. Cov teeb meem xav tau kev saib xyuas hauv cov khoom siv hluav taws xob sib txuas
Kev sib txuas ntawm cov khoom siv hluav taws xob yuav tsum ua raws li qee qhov kev qhia tshwj xeeb, txwv tsis pub nws yuav ua rau cov khoom siv hluav taws xob tsis ruaj khov, lub zog hluav taws xob luv luv, cov khoom puas thiab lwm yam teeb meem. Nov yog ob peb yam uas yuav tsum tau saib xyuas:
(1) cov qauv siv hluav taws xob yuav tsum sib xws.
Ntau yam khoom siv hluav taws xob hloov hluav taws xob sib txuas ua ke yuav tsum siv tib hom kev hloov hluav taws xob hloov hluav taws xob, txhawm rau kom ntseeg tau tias lawv cov zis hluav taws xob thiab cov hluav taws xob zoo ib yam. Yog tias cov khoom siv hluav taws xob sib txawv sib txuas ua ke, lub zog tso zis thiab kev ruaj ntseg ntawm cov khoom siv fais fab yuav raug cuam tshuam.
(2) Qhov ntev ntawm cov cables txuas nrog rau kev sib txuas yuav tsum zoo ib yam.
Rau ntau yam khoom siv hluav taws xob hloov hluav taws xob sib txuas ua ke, lawv cov zis voltage thiab tam sim no yuav tsum nyob rau hauv tib qhov voltage thiab tam sim no ntau yam. Txawm li cas los xij, kev sib txuas ntawm cov xov hlau nrog qhov ntev sib txawv yuav ua rau muaj kev hloov pauv impedance thiab qhov hluav taws xob poob, uas yuav ua rau cov khoom siv hluav taws xob tsis ruaj khov. Yog li ntawd, lub cable ntev yuav tsum yog tib yam thiab txoj kab uas hla ntawm lub xaim yuav tsum yog tib yam, thiaj li ua kom muaj kev ruaj ntseg ntawm cov zis voltage thiab tam sim no ntawm cov khoom siv hluav taws xob.
(3) Qhov kawg ntawm cov khoom siv hluav taws xob hloov hluav taws xob yuav tsum tau txuas nrog lub nra hnyav.
Cov khoom siv hluav taws xob hloov pauv ntau qhov sib txuas ua ke yuav tsum tau txuas nrog cov khoom sib txawv kom siv tag nrho cov zis hluav taws xob. Yog hais tias cov zis terminals ntawm ntau cov khoom siv hluav taws xob sib koom ua ke, qhov tsis ua haujlwm ntawm ib lub zog hluav taws xob yuav ua rau cov zis ntau dhau ntawm cov khoom sib koom, yog li ua rau lub nra hnyav.
(4) Cov zis tam sim no ntawm cov khoom siv hluav taws xob sib txuas yuav tsum sib npaug.
Thaum cov khoom siv hluav taws xob hloov pauv tau sib txuas ua ke, lawv cov zis tam sim no yuav tsum sib npaug, uas tuaj yeem zam qhov teeb meem uas cov zis tam sim no ntawm ib qho hluav taws xob loj dhau. Yog tias cov zis tam sim no ntawm ntau cov khoom siv hluav taws xob sib txawv, cov khoom siv hluav taws xob nrog cov tam sim no me me tuaj yeem ua haujlwm dhau thaum lub sijhawm ua haujlwm, yog li cuam tshuam rau kev ua haujlwm ntawm lub zog.
(5) Thaum cov zis hluav taws xob txuas nrog rau tib lub sijhawm, lub cable interface yuav tsum raug tiv thaiv.
Thaum muaj ntau yam khoom siv hluav taws xob hloov pauv tau sib txuas ua ke, cov cables txuas cov khoom siv hluav taws xob yuav tsum tau tiv thaiv. Vim tias nyob rau hauv lub zog siab, siab voltage thiab siab tam sim no, qhov sib koom ua ke yuav loosen, yog li tsim lub teeb arc. Nyob rau tib lub sijhawm, kev sib koom ua ke ntawm kev sib txuas ntawm kev sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum tau tshuaj xyuas thiab khaws cia tsis tu ncua kom tsis txhob muaj kev sib cuag tsis zoo ntawm kev sib koom tes thiab kev laus ntawm cov ntaub ntawv rwb thaiv tsev.
