Yog hais tias ib tug neeg dheev hais txog lub hwj chim adapter rau koj, tej zaum koj yuav xav tias lub hwj chim adapter yog dab tsi, tab sis koj yuav tsis xav tias nws yog nyob rau hauv lub ces kaum ib ncig ntawm koj uas koj yuav luag tsis nco qab lawm. Muaj ntau cov khoom lag luam suav nrog nws, xws li lub khoos phis tawj, lub koob yees duab kev ruaj ntseg, rov ua dua, cov thawv ntim khoom, nws cov khoom, cov khoom ua si, suab, teeb pom kev zoo, thiab lwm yam khoom siv, Nws txoj haujlwm yog los hloov cov hluav taws xob siab ntawm 220 V hauv tsev rau hauv ruaj khov tsis tshua muaj hluav taws xob txog li 5V ~ 20V uas cov khoom siv hluav taws xob no tuaj yeem ua haujlwm. Hnub no, kuv yuav qhia rau kuv cov phooj ywg kom paub meej tias lub hwj chim adapter yog dab tsi.
Feem ntau, lub hwj chim adapter yog tsim los ntawm lub plhaub, high-frequency transformer, hlau, PCB Circuit Court board, hardware, inductance, capacitor, tswj IC thiab lwm yam, raws li nram no:
1. Lub luag haujlwm ntawm varistor yog tias thaum lub sijhawm tam sim no sab nraud thiab qhov hluav taws xob siab dhau lawm, qhov kev tiv thaiv ntawm varistor sai sai heev, thiab lub fuse txuas nrog varistor hauv series yog tshuab, thiaj li tiv thaiv lwm lub zog hluav taws xob los ntawm kev kub hnyiab.
2. Fuse, nrog rau cov lus qhia ntawm 2.5a / 250v. Thaum tam sim no nyob rau hauv lub hwj chim Circuit Court loj heev, lub fuse yuav tshuab los tiv thaiv lwm yam khoom.
3. Inductance coil (tseem hu ua choke coil) feem ntau yog siv los txo cov electromagnetic cuam tshuam.
4. Rectifier choj, d3sb hauv specification, yog siv los hloov 220V AC rau DC.
5. Lub lim capacitor yog 180uf / 400V, uas tuaj yeem lim cov AC ripple hauv DC thiab ua rau kev ua haujlwm ntawm lub zog hluav taws xob ntau dua.
6. Kev ua haujlwm amplifier IC (integrated circuit) yog ib feem tseem ceeb ntawm kev tiv thaiv hluav taws xob hluav taws xob thiab kev tswj xyuas tam sim no thiab voltage.
7. Qhov ntsuas kub yog siv los ntsuas qhov ntsuas kub ntawm lub hwj chim adapter. Thaum qhov kub thiab txias siab tshaj li ib qho kev teeb tsa tus nqi (qhov ntsuas kub ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv me ntsis), kev tiv thaiv hluav taws xob hluav taws xob yuav txiav tawm tam sim no thiab qhov hluav taws xob tawm ntawm lub adapter, yog li lub adapter yuav tsis puas.
8. Lub raj xa hluav taws xob siab yog ib qho ntawm cov khoom tseem ceeb hauv lub hwj chim adapter. Lub hwj chim adapter tuaj yeem ua haujlwm "rau thiab tawm", thiab lub zog ntawm lub raj hloov pauv yog qhov tseem ceeb.
9. Hloov transformer yog ib qho ntawm cov khoom tseem ceeb hauv lub hwj chim adapter.
10. Qhov thib ob rectifier hloov low-voltage AC mus rau low-voltage DC. Nyob rau hauv IBM lub hwj chim adapter, lub rectifier feem ntau yog ua los ntawm ob lub zog siab nyob rau hauv parallel kom tau txais cov zis tam sim no loj heev.
11. Muaj ob lub lim dej thib ob nrog cov kev qhia tshwj xeeb ntawm 820uf / 25V, uas tuaj yeem lim cov ripple hauv qis-voltage DC. Ntxiv nrog rau cov khoom siv saum toj no, muaj cov potentiometers kho tau thiab lwm yam kev tiv thaiv kev ua haujlwm ntawm lub rooj tsav xwm Circuit Court.
