Ib lub transformer yog siv rau kauj ruam -} thiab kauj ruam- Nws muaj ob coils, lub npe hu ua Thawj Wullings thiab cov khoom siv sib txawv, uas tau lub qhov txhab ib puag ncig cov tub ntxhais sib nqus. Thaum lwm txoj kev hloov pauv tam sim no (AC) ntws los ntawm kev ua cua, nws tsim cov kev hloov sib xyaw sib xyaw hauv cov tub ntxhais. Qhov no hloov kev hloov sib nqus teb tsim ib qho hluav taws xob qhov hluav taws xob hauv cov winder thib ob.
Tus yuam sij rau kauj ruam -}}-}}}}}) rau tus naj npawb ntawm cov thib ob ntawm winder (n₂):
- Kauj Ruam -} li transformer: Yog hais tias lub winding thib ob tau ntau dua lem ntau dua li cov winding thawj (n₂> Qhov kev teeb tsa no yog siv los nce qib volageage.
- Kauj -} down transformer: Yog hais tias lub winding theem nrab muaj tsawg dua li cov cua daj cua dub (n₂
Yog li, los ntawm kev kho cov lem sib piv, tus hloov pauv tau nce qib los yog nqis ntaiv, ua rau nws muaj kev cuam tshuam tseem ceeb hauv kev faib khoom fais fab.
