Thaum siv DC lub zog hloov hluav taws xob, nws yog qhov kev xav tsis zoo vim tias lub tshuab hloov pauv tau siv los hloov pauv tam sim no (AC) voltages, tsis yog tam sim no (DC) voltages. Transformers ua hauj lwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, uas yuav tsum tau AC zog ntawm ob lub hauv paus (input side) thiab theem nrab (sab tso zis).
Txawm li cas los xij, yog tias koj muaj lub cuab yeej lossis lub kaw lus uas xav tau DC, tab sis koj lub hwj chim yog AC, ces koj feem ntau yuav siv lub rectifier (tej zaum tus choj rectifier) los hloov AC rau DC. Kev sib raug zoo ntawm AC amperage (los yog tam sim no) thiab DC amperage yog qhov tseem ceeb hauv cov txheej txheem no.
Txoj kev txiav txim siab AC amperage yog raws li nram no:
1. ** Txiav txim siab DC tam sim no yuav tsum tau ntawm lub Load **: Ua ntej, koj yuav tsum paub seb koj cov khoom siv tam sim no lossis qhov system xav tau ntawm DC. Qhov no feem ntau tuaj yeem pom hauv cov khoom siv cov ntawv qhia tshwj xeeb lossis phau ntawv qhia kev.
2. ** Xaiv Rectifier **: Xaiv lub rectifier tsim nyog uas yuav hloov AC tam sim no mus rau DC tam sim no. Rectifiers yuav txawv ntawm qhov ua tau zoo (piv txwv li, lawv hloov AC rau DC tau zoo npaum li cas), yog li koj yuav tsum sab laj nrog lub rectifier daim ntawv qhia kom paub seb nws zoo npaum li cas.
3. **Xaiv AC tam sim no**: Txhawm rau xam qhov xav tau AC tam sim no, koj tuaj yeem siv cov qauv hauv qab no:
AC tam sim no (A)=DC tam sim no (A) / Rectifier Efficiency
Piv txwv li, yog tias koj lub cuab yeej xav tau 5A ntawm DC tam sim no thiab koj lub rectifier qhov ua tau zoo yog 80%, AC tam sim no koj xav tau yog:
AC tam sim no (A) {{0}}A / 0.8=6.25A
4. **Xaiv lub transformer**: Thaum kawg, xaiv lub transformer uas nws cov zis tam sim no yog tsawg kawg yog xam AC tam sim no. Xav txog qhov ua tau zoo ntawm transformer thiab qhov ua tau qhov voltage poob, koj yuav tau xaiv ib tug me ntsis loj transformer.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kauj ruam saum toj no yog cov txheej txheem yooj yim thiab qhov kev xaiv tiag tiag yuav txawv nyob ntawm qhov tshwj xeeb daim ntawv thov, yam ntxwv ntawm cov khoom siv, thiab lwm yam. Thaum tsim thiab xaiv cov khoom siv hluav taws xob, nws raug nquahu kom ua tib zoo xav txog txhua yam tseem ceeb thiab xa mus rau cov qauv tsim hluav taws xob thiab cov kev coj ua zoo tshaj plaws.
Ua raws li peb thiab koj yuav kawm ntxiv txog transformers thiab lub zog hloov dua siab tshiab.
