Ngati wina akuuzani mwadzidzidzi adaputala yamagetsi kwa inu, mungadabwe kuti adaputala yamagetsi ndi chiyani, koma simungayembekeze kuti ili pakona pomwe mwaiwala. Pali zinthu zambiri zofananira nazo, monga ma laputopu, makamera otetezera, obwereza, mabokosi apamwamba, zinthu, zoseweretsa, zomvera, zowunikira, ndi zida zina, Ntchito yake ndikutembenuza ma voliyumu apamwamba a 220 V kunyumba kukhala magetsi. voteji otsika okhazikika pafupifupi 5V ~ 20V omwe zinthu zamagetsi izi zitha kugwira ntchito. Lero, ndidziwitsa anzanga mwatsatanetsatane chomwe adapter yamagetsi.
Nthawi zambiri, adaputala mphamvu amapangidwa ndi chipolopolo, high-frequency thiransifoma, waya, PCB dera bolodi, hardware, inductance, capacitor, ulamuliro IC ndi mbali zina, motere:
1. Ntchito ya varistor ndi yakuti pamene kunja kwamakono ndi magetsi kuli kwakukulu kwambiri, kukana kwa varistor mwamsanga kumakhala kochepa kwambiri, ndipo fusesi yolumikizidwa ndi varistor mndandanda imawombedwa, kuti ateteze maulendo ena amphamvu kuti asawotchedwe.
2. Fuse, ndi ndondomeko ya 2.5a / 250v. Pamene mphamvu mu dera lamagetsi ndi yaikulu kwambiri, fuseyi idzawombera kuti iteteze zigawo zina.
3. Koyilo ya inductance (yomwe imadziwikanso kuti choke coil) imagwiritsidwa ntchito makamaka kuchepetsa kusokoneza kwa ma elekitiroma.
4. Mlatho wokonzanso, d3sb mwatsatanetsatane, umagwiritsidwa ntchito kutembenuza 220V AC kukhala DC.
5. Fyuluta capacitor ndi 180uf / 400V, yomwe imatha kusefa AC ripple mu DC ndikupanga ntchito yamagetsi yodalirika.
6. IC amplifier yogwira ntchito (integrated circuit) ndi gawo lofunika kwambiri la chitetezo cha magetsi oyendetsa magetsi komanso kayendetsedwe kamakono ndi magetsi.
7. Kufufuza kwa kutentha kumagwiritsidwa ntchito kuti azindikire kutentha kwa mkati mwa adaputala yamagetsi. Pamene kutentha kuli kwakukulu kuposa mtengo wina wokhazikika (chiwongolero cha kutentha kwa mitundu yosiyanasiyana ya ma adapter amagetsi ndi osiyana pang'ono), dera lamagetsi lachitetezo lidzadula mphamvu zamakono ndi magetsi a adaputala, kotero kuti adaputala siiwonongeka.
8. Chubu chosinthira mphamvu kwambiri ndi chimodzi mwazinthu zofunika kwambiri mu adaputala yamagetsi. Adaputala yamagetsi imatha kugwira ntchito "kuyatsa ndi kuzimitsa", ndipo mphamvu ya chubu yosinthira ndiyofunikira.
9. Kusintha kwa transformer ndi chimodzi mwa zinthu zofunika kwambiri mu adaputala yamagetsi.
10. Chowonjezera chachiwiri chimasintha AC yamagetsi otsika kukhala DC yamagetsi otsika. Mu adaputala yamagetsi ya IBM, chowongoleracho nthawi zambiri chimayendetsedwa ndi mphamvu ziwiri zofananira kuti zipeze kutulutsa kwakukulu komweko.
11. Pali ma capacitor awiri achiwiri a fyuluta omwe ali ndi mawonekedwe a 820uf / 25V, omwe amatha kusefa ripple mu DC yotsika kwambiri. Kuphatikiza pazigawo zomwe tazitchulazi, pali ma potentiometers osinthika ndi zida zina zamphamvu pagulu ladera.
