Kana mumwe munhu akangoerekana ataura nezve adapta yemagetsi kwauri, unogona kushamisika kuti iyo adapta yemagetsi chii, asi iwe ungasatarisira kuti iri mukona yakakupoteredza iwe wapotsa wakanganwa.Kune zvisingaverengeki zvigadzirwa zvakafananidzwa nazvo, zvakaita semalaptops, makamera ekuchengetedza, anodzokorora, set-yepamusoro mabhokisi, iwo zvigadzirwa, matoyi, odhiyo, mwenje, uye zvimwe midziyo, Basa rayo nderekushandura yakakwira voltage ye220 V kumba kuita yakagadzikana yakaderera voltage inosvika 5V ~ 20V iyo zvigadzirwa zvemagetsi izvi zvinogona kushanda.Nhasi, ini ndichasuma kushamwari dzangu zvakadzama kuti chii chinonzi adapta yemagetsi.
Kazhinji, iyo adapta yemagetsi inoumbwa negoko, yakakwira-frequency transformer, waya, PCB redunhu bhodhi, Hardware, inductance, capacitor, control IC uye zvimwe zvikamu, sezvinotevera:
1. Basa revaristor nderokuti kana kunze kwezvino uye magetsi zvakanyanya, kushorwa kwevaristor kunokurumidza kuva kuduku, uye fuse yakabatana nevaristor mumutsara inoputika, kuitira kuchengetedza mamwe magetsi emagetsi kubva pakupiswa.
2. Fuse, ine tsanangudzo ye 2.5a / 250v.Kana ikozvino mumagetsi emagetsi yakakura zvikuru, fuse inoputika kudzivirira zvimwe zvikamu.
3. Inductance coil (inonziwo choke coil) inonyanya kushandiswa kuderedza kukanganiswa kwemagetsi.
4. Rectifier bhiriji, d3sb mune yakatarwa, inoshandiswa kushandura 220V AC kuita DC.
5. Iyo sefa capacitor ndeye 180uf / 400V, iyo inogona kusefa iyo AC ripple muDC uye kuita kuti kushanda kwesimba remagetsi kuve kwakavimbika.
6. Operational amplifier IC (integrated circuit) chikamu chinokosha chekudzivirira simba rekugadzirisa magetsi uye ikozvino uye mutemo wemagetsi.
7. Iyo tembiricha probe inoshandiswa kuona kupisa kwemukati kweiyo adapta yemagetsi.Kana tembiricha yakakwira kupfuura imwe seti kukosha (iyo yakatarwa tembiricha chikumbaridzo chemhando dzakasiyana dzemagetsi adapter chakasiyana zvishoma), iyo yekudzivirira simba redunhu inocheka yazvino uye voltage kubuda kweadapta, saka adapta haizokuvadzwa.
8. I-high-power switch tube ndiyo imwe yezvikamu zvakakosha mumagetsi emagetsi.Iyo adapta yemagetsi inogona kushanda "pakudzima nekudzima", uye simba reiyo switch chubhu yakakosha.
9. Kushandura transformer chimwe chezvinhu zvinokosha mumagetsi emagetsi.
10. Iyo yechipiri rectifier inoshandura yakaderera-voltage AC kuita yakaderera-voltage DC.MuIBM's power adapter, iyo inogadziridza inowanzo shandiswa neaviri epamusoro-simba akaenderana kuti awane yakakura kuburitsa ikozvino.
11. Kune maviri echipiri mafirita capacitors ane tsanangudzo ye820uf / 25V, iyo inogona kusefa ripple mu low-voltage DC.Pamusoro pezvikamu zviri pamusoro apa, pane zvinogadziriswa potentiometers uye zvimwe zvinopikisa capacitance zvikamu pabhodhi redunhu.
