Haeba motho ka tšohanyetso a bua ka adapter ea matla ho uena, u ka 'na ua ipotsa hore na adapter ea matla ke eng, empa u ka' na ua se ke ua lebella hore e sekhutlong se u potolohileng hoo u batlang u se u lebetse. Ho na le lihlahisoa tse ngata tse tsamaellanang le eona, joalo ka lilaptop, lik'hamera tsa ts'ireletso, li-repeter, mabokose a holimo, lihlahisoa, lintho tsa ho bapala, molumo, mabone le lisebelisoa tse ling, mosebetsi oa eona ke ho fetola matla a phahameng a 220 V lapeng hore e be motlakase. matla a tlaase a tsitsitseng a ka bang 5V ~ 20V ao lihlahisoa tsena tsa elektronike li ka sebetsang. Kajeno, ke tla tsebisa metsoalle ea ka ka botlalo hore na adaptara ea motlakase ke eng.
Ka kakaretso, adaptara ea matla e entsoe ka khetla, sefetoleli se phahameng sa maqhubu, terata, boto ea potoloho ea PCB, hardware, inductance, capacitor, control IC le likarolo tse ling, ka tsela e latelang:
1. Mosebetsi oa varistor ke hore ha motlakase o ka ntle le motlakase o phahame haholo, khanyetso ea varistor e fetoha e nyenyane haholo, 'me fuse e amanang le varistor ka letoto le phunyeletsoa, e le ho sireletsa lipotoloho tse ling tsa matla hore li se ke tsa chesoa.
2. Fuse, e nang le litlhaloso tsa 2.5a / 250v. Ha motlakase oa potoloho ea motlakase o le moholo haholo, fuse e tla fofa ho sireletsa likarolo tse ling.
3. Inductance coil (eo hape e tsejoang e le choke coil) e sebelisoa haholo ho fokotsa tšitiso ea motlakase.
4. Borokho ba Rectifier, d3sb ka litlhaloso, bo sebelisoa ho fetolela 220V AC ho DC.
5. Filter capacitor ke 180uf / 400V, e ka hloekisang AC ripple ho DC le ho etsa hore ts'ebetso ea potoloho ea matla e tšepahale haholoanyane.
6. IC ea amplifier ea ts'ebetso (potoloho e kopantsoeng) ke karolo ea bohlokoa ea potoloho ea phepelo ea matla a tšireletso le taolo ea hona joale le ea motlakase.
7. Sesebelisoa sa mocheso se sebelisetsoa ho lemoha mocheso o ka hare oa adapter ea matla. Ha mocheso o phahame ho feta boleng bo itseng bo behiloeng (mocheso o behiloeng oa lihlahisoa tse fapaneng tsa li-adapter tsa matla o fapane hanyenyane), potoloho ea matla a tšireletso e tla khaola tlhahiso ea hona joale le ea motlakase ea adaptara, kahoo adaptara e ke ke ea senyeha.
8. Tube ea ho fetola matla a phahameng ke e 'ngoe ea likarolo tsa bohlokoa ho adaptara ea matla. Adapter ea matla e ka sebetsa "ho tima le ho tima", 'me matla a switch tube ke a bohlokoa haholo.
9. Ho fetola transformer ke e 'ngoe ea likarolo tsa bohlokoa ho adapter ea matla.
10. Rectifier ea bobeli e fetola low-voltage AC hore e be low-voltage DC. Ho adaptara ea matla ea IBM, rectifier hangata e sebelisoa ke matla a mabeli a holimo ka ho bapa ho fumana tlhahiso e batlang e le kholo ea hajoale.
11. Ho na le li-capacitor tse peli tsa bobeli tsa filthara tse nang le lintlha tsa 820uf / 25V, tse ka sefang ripple ka DC e nang le matla a tlase. Ho phaella ho likarolo tse ka holimo, ho na le potentiometers e feto-fetohang le likarolo tse ling tsa matla a ho hanyetsa boto ea potoloho.
