Cov tshuab hluav taws xob tam sim no tuaj yeem siv rau hauv DC daim ntawv thov, txawm hais tias nws nthuav tawm qee qhov kev sib tw piv rau AC daim ntawv thov.
1. Txoj Cai thiab Kev Hloov Kho rau DC
Feem ntau cov tsoos tam sim no transformers cia siab rau qhov hloov pauv magnetic teb uas tsim los ntawm kev hloov tam sim no los ua kom muaj qhov hluav taws xob nyob rau hauv qhov thib ob winding. Txawm li cas los xij, cov tshuab hluav taws xob tam sim no tuaj yeem siv lwm txoj hauv kev rau kev ntsuas DC. Piv txwv li, Hall-effect-based electronic tam sim no transformers tuaj yeem ntsuas DC tam sim no. Lub Hall effect sensor pom cov hlau nplaum tsim los ntawm DC tam sim no-nqa tus neeg xyuas pib. Lub zog ntawm lub magnetic teb yog ncaj qha proportional rau DC, thiab lub sensor converts cov ntaub ntawv magnetic teb no mus rau hauv ib tug hluav taws xob teeb liab uas yuav ua tau ntxiv thiab ntsuas.
2. Cov kev sib tw hauv DC Kev Ntsuas
Ib qho ntawm cov teeb meem tseem ceeb hauv kev siv hluav taws xob tam sim no transformers rau DC daim ntawv thov yog qhov muaj qhov sib nqus teb offsets thiab drifts. Hauv DC systems, txhua qhov kev hloov me me hauv qhov chaw sib nqus lossis cov yam ntxwv ntawm lub sensor nws tus kheej tuaj yeem ua rau kev ntsuas tsis raug. Piv txwv li, kev hloov pauv kub tuaj yeem cuam tshuam rau kev ua haujlwm ntawm Hall-effect sensor thiab ua rau muaj kev hloov pauv hauv qhov ntsuas DC tus nqi. Tsis tas li ntawd, DC magnetic teb tuaj yeem ua rau cov hlau nplaum sib nqus (yog tias tam sim no) yooj yim dua li hauv AC daim ntawv thov, uas tuaj yeem ua rau kev nyeem ntawv tsis raug.
3. Cov txheej txheem them nyiaj thiab calibration
Txhawm rau kov yeej cov teeb meem no, cov nyiaj them siab tshaj thiab kev ntsuas ntsuas tau siv. Cov hluav taws xob tam sim no transformers rau DC daim ntawv thov feem ntau suav nrog qhov kub thiab txias circuits. Cov kab hluav taws xob no kho cov teeb liab tso tawm raws li qhov ntsuas kub kom kho rau qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas. Cov txheej txheem ntsuas ntsuas kuj tseem ceeb dua rau cov ntawv thov DC kom paub meej thiab ruaj khov ntsuas lub sijhawm. Los ntawm kev ua tib zoo ntsuas thiab siv cov txheej txheem them nyiaj tsim nyog, cov khoom siv hluav taws xob tam sim no tuaj yeem muab kev ntsuas tam sim no hauv DC daim ntawv thov.
