Yuav siv cov khoom siv hluav taws xob hloov pauv li cas?
Switching fais fab mov yog siv dav siv hluav taws xob 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 zog hluav taws xob thiab cov zis tam sim no, ua rau nws nyiam lub zog hluav taws xob rau ntau yam khoom siv hluav taws xob. Txawm li cas los xij, qee zaum, ib qho kev hloov hluav taws xob ib leeg tsis tuaj yeem ua tau raws li qhov xav tau, thiab ntau lub zog hloov hluav taws xob yuav tsum tau siv ua ke. Nyob rau hauv tsab xov xwm no, peb yuav muab cov ncauj lus kom ntxaws qhia txog yuav ua li cas siv switching fais fab mov outputs nyob rau hauv parallel.
1. Lub hauv paus ntsiab lus ntawm kev sib txuas ua ke
Kev sib txuas ntawm ntau lub zog hloov hluav taws xob tso tawm ua rau lawv tuaj yeem ua ke rau hauv lub zog tso zis ntau dua. 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 lub zog hluav taws xob thiab txuas tag nrho cov ncej tsis zoo ntawm lub zog hluav taws xob. Qhov no tuaj yeem koom tes nrog txhua qhov chaw siv hluav taws xob thiab sib koom ua ke tso tawm cov hluav taws xob loj dua thiab qhov hluav taws xob. Ntau qhov chaw siv hluav taws xob txuas nrog tib lub sijhawm, txhua tus uas tso tawm tib qhov voltage thiab tam sim no. Yog hais tias tus naj npawb ntawm cov khoom siv hluav taws xob sib xyaw ua ke ntau dua, cov zis hluav taws xob kuj tseem ntau dua.
2. Muaj feem xyuam rau cov khoom siv hluav taws xob sib txuas
Ntau lub zog 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, lub cev muaj zog ceev, zaus hloov pauv, 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 ntawm ntau yam khoom siv hluav taws xob hloov pauv tuaj yeem ua rau cov khoom siv hluav taws xob ntau ntxiv thiab ua tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob, high-voltage, thiab cov ntawv thov tam sim no.
3. Kev ceev faj rau cov khoom siv hluav taws xob sib txuas
Kev sib txuas ntawm cov khoom siv hluav taws xob yuav tsum ua raws li qee cov qauv, txwv tsis pub nws yuav ua rau cov khoom siv hluav taws xob tsis ruaj khov, lub neej luv zog, khoom siv puas tsuaj, thiab lwm yam teeb meem. Nov yog ob peb yam uas yuav tsum nco ntsoov:
(1) Cov qauv siv hluav taws xob yuav tsum sib xws
Ntau cov khoom siv hluav taws xob hloov pauv nyob rau hauv tib lub sijhawm yuav tsum siv tib tus qauv ntawm kev hloov hluav taws xob los xyuas kom meej tias lawv cov zis voltage thiab tam sim no zoo ib yam. Yog tias cov qauv sib txawv ntawm cov khoom siv hluav taws xob sib txuas ua ke, cov zis hluav taws xob thiab kev ruaj ntseg ntawm cov khoom siv hluav taws xob yuav raug cuam tshuam.
(2) Qhov ntev ntawm cov cables txuas nrog rau kev sib txuas yuav tsum zoo ib yam
Rau ntau cov 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. Qhov ntev ntawm kev sib txuas ntawm cov xov hlau sib txawv tuaj yeem ua rau muaj kev hloov pauv impedance thiab qhov hluav taws xob poob, uas tuaj yeem 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 txoj kab uas hla yuav tsum yog tib yam los xyuas kom meej qhov ruaj khov ntawm lub zog tso zis voltage thiab tam sim no.
(3) Cov zis terminals ntawm lub zog hloov hluav taws xob yuav tsum txuas nrog cov khoom sib cais
Ntau yam khoom siv hluav taws xob hloov pauv txuas nrog rau kev sib txuas yuav tsum tau txuas nrog cov khoom sib txawv kom siv cov khoom siv hluav taws xob tag nrho. Yog hais tias cov zis terminals ntawm ntau cov khoom siv hluav taws xob sib koom ua ke, qhov tsis ua haujlwm ntawm ib qho ntawm cov khoom siv hluav taws xob yuav ua rau cov zis tam sim no ntawm cov khoom sib koom siab dhau lawm, yog li ua rau lub nra hnyav.
(4) Cov kev xav tau tam sim no ntawm cov khoom siv hluav taws xob sib npaug sib npaug
Thaum muaj ntau yam khoom siv hluav taws xob hloov pauv tau sib txuas ua ke, lawv cov zis tam sim no yuav tsum sib npaug kom tsis txhob tshwm sim ntawm cov khoom siv hluav taws xob ntau dhau los ntawm ib qho khoom siv hluav taws xob. 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 yuav muaj kev cuam tshuam ntau dhau thaum lub sijhawm ua haujlwm, uas tuaj yeem 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 tau txuas rau kev tiv thaiv
Thaum cov khoom siv hluav taws xob hloov pauv ntau qhov tso tawm nyob rau hauv tib lub sijhawm, cov kab txuas txuas ntawm cov khoom siv hluav taws xob yuav tsum tau tiv thaiv. Vim hais tias nyob rau hauv lub zog siab, high voltage, thiab siab tam sim no, lub connector tej zaum yuav xoob, ua rau arc teeb. Nyob rau tib lub sijhawm, kev sib koom ua ke ntawm cov khoom siv hluav taws xob sib txuas ua ke yuav tsum tau soj ntsuam tas li thiab tswj xyuas kom tsis txhob muaj teeb meem xws li kev sib cuag tsis zoo ntawm kev sib koom tes thiab kev laus ntawm cov khoom siv rwb thaiv tsev.
