Sebakeng sa kajeno sa indasteri le tsa elektroniki tse ntseng li hola ka potlako, phepelo ea motlakase ea DC e bapala karolo ea bohlokoa ho netefatsa ts'ebetso e tsitsitseng le e ts'epahalang lits'ebetsong tse fapaneng tse fapaneng - ho tloha ho li-automation tsa feme ho ea ho marang-rang a likhokahano, li-labs tsa liteko le litsamaiso tsa matla.
Phepelo ea Matla a DC ke eng?
Motlakase oa DC (Direct Current) ke sesebelisoa se fanang ka motlakase o tsitsitseng o tobileng kapa oa hona joale, hangata ka ho fetola alternating current (AC) ho tloha grid kapa mohloling o mong oa matla ho ea hona joale. Letšoao la tlhahiso ea DC ke polarity ea eona e sa fetoheng - e ntse e phalla ka mokhoa o tsitsitseng ho tloha setsing se setle ho ea ho terminal e mpe, e leng bohlokoa bakeng sa lipotoloho tsa elektroniki tse hlokolosi le lisebelisoa tse nepahetseng.
Ntle le phetoho ea AC-DC, lisebelisoa tse ling tsa motlakase tsa DC li fumana matla ho tsoa lik'hemik'hale (mohlala, libeteri) kapa mehloli e ka nchafatsoang (mohlala, letsatsi).
Lihlopha tse ka sehloohong tsa Lisebelisoa tsa Matla a DC
Lisebelisoa tsa motlakase tsa DC li tla ka mefuta e fapaneng ho latela litlhoko tsa tlhahiso, taolo e nepahetseng, mohloli oa matla le boholo. Ka tlase ke mefuta e sebelisoang haholo:
●Linear Power Supply
Mofuta ona o sebelisa potoloho ea transformer le rectifier ho theola fatše le ho fetolela AC ho DC, e lateloe ke taolo ea motlakase ea mola ho thella sephetho.
● Melemo: Lerata le tlaase le molumo o fokolang
● Moeli: Boholo bo boholo le bo sebetsang bo tlase ha bo bapisoa le mekhoa ea ho fetola
● Molemo ka ho fetisisa bakeng sa: Tšebeliso ea laboratori, potoloho ea analog
●FetohangPhepelo ea motlakase
Ka ho fetoha ha maqhubu a phahameng le likarolo tsa polokelo ea matla joalo ka li-inductors kapa li-capacitor, SMPS e fana ka phetoho e nepahetseng ea motlakase.
● Melemo: Ho sebetsa hantle haholo, boholo bo kopanetsoeng
● Tekanyetso: E ka hlahisa EMI (electromagnetic interference)
● Molemo ka ho fetisisa bakeng sa: Boiketsetso ba indasteri, lisebelisoa tsa LED, mehala ea puisano
●Phepelo ea Matla a Laoloang ke Voltage
E etselitsoe ho boloka motlakase oa motlakase o tsitsitseng, leha o na le ho feto-fetoha ha matla a ho kenya kapa phapano ea mojaro.
● E ka kenngoa tšebetsong e le linear kapa switching system
● Molemo ka ho fetisisa bakeng sa: Lisebelisoa tse lemohang ho se tsitse ha motlakase
●Phepelo ea Matla a Kamehla Hajoale
E fana ka tlhahiso e tsitsitseng ea hona joale, ho sa tsotellehe liphetoho tsa ho hanyetsa mojaro.
● Molemo ka ho fetisisa bakeng sa: Ho khanna ka LED, electroplating, lisebelisoa tsa ho tjhaja betri
● Phepelo ea Matla a Thehiloeng Betring
Libetri li sebetsa e le mehloli ea DC e nkehang le e ikemetseng, e fetola matla a lik'hemik'hale hore e be matla a motlakase.
● Melemo: Ho nkeha habonolo, ho ikemela ho grid
● Molemo ka ho fetisisa bakeng sa: Mehala ea elektronike, lisebelisoa tsa matla tsa bekapo
●Letsatsi MatlaPhepelo
E sebelisa liphanele tsa letsatsi ho fetolela khanya ea letsatsi hore e be motlakase oa DC. Ka tloaelo e tsamaisana le polokelo ea betri le lilaoli tsa tefiso bakeng sa tlhahiso e tšepahalang.
● Molemo ka ho fetisisa bakeng sa: Lits'ebetso tse kantle ho grid, litsamaiso tsa motlakase tse tšoarellang
Lisebelisoa tsa Teko: Karolo ea Meroalo ea Elektronike
Bakeng sa ho netefatsa ts'ebetso ea lisebelisoa tsa motlakase tsa DC tlasa maemo a fapaneng a mojaro, ho sebelisoa meroalo ea elektroniki. Lisebelisoa tsena tse hlophisehang li thusa bahlahisi le lienjineri ho etsisa ts'ebeliso ea lefatše la 'nete le ho netefatsa botsitso.
Ho Khetha Phepelo ea Matla a DC e Nepahetseng
Ho khetha motlakase o nepahetseng oa DC ho itšetlehile ka:
● Matla a motlakase a kopo ea hau le litlhoko tsa hajoale
● Ho mamella ho ripeha le lerata
● Litlhoko tsa ho sebetsa hantle le mathata a sebaka
● Maemo a tikoloho (thempereichara, mongobo, ho fumaneha ha marang-rang)
Mofuta o mong le o mong oa phepelo ea motlakase o na le matla a ikhethang - ho utloisisa phapang ena ke senotlolo sa ho ntlafatsa ts'ebetso le ts'epo ea sistimi ea hau.
Mofani oa Hao ea Tšepahalang bakeng sa Litharollo tsa Matla a Matla a DC
At Phepelo ea Matla a Xingtongli, re fana ka bobeli maemo lecustomized DC phepelo ea motlakase ho bareki lefatšeng ka bophara. Hore na o hloka li-rectifiers tsa morao-rao tsa morao-rao, li-lab tse hlophisehang, kapa mehloli ea DC e sebeletsanang le letsatsi - re ikemiselitse ho khotsofatsa litlhoko tsa hau ka tšehetso ea litsebi, thomello ea thepa lefatšeng ka bophara, le litharollo tse lokiselitsoeng.
