Muaj nuj nqi ntawm transformer
Dec 25, 2020
Transformer (transformer) yog ib qho khoom siv hluav taws xob uas nws lub zog muaj peev xwm raug faib ua txoj haujlwm hauv qab no:
1. Koj tuaj yeem nce lossis txo tus nqi ntawm AC voltage lossis tam sim no ntawm qhov yuav
2. Siv raws li cov cuab yeej ua tsis taus ntxiv: Kev hloov pauv tuaj yeem siv los ua kom qhov khoob uas tsis muaj qhov sib txawv. Piv txwv li cov zis impedance ntawm qee yam amplifier yog 20 ohms, thiab nws txuas nrog rau 4 ohm hais lus. Nyob rau lub sijhawm no, lub tshuab hloov pauv yuav tsum raug siv nrog ob qhov kev cuam tshuam nrog qhov ntsuas hloov tau qhov tseeb.
3. Siv rau cov teeb liab kis. Qee lub cim yuav tsum raug rho tawm hluav taws xob. Lub sijhawm no, tus hloov hluavtaws xob muaj txiaj ntsig zoo.
4. Siv thiab hluav taws xob oscillation Circuit Court ua cov lus tawm tswv yim
Lub tshuab hluav taws xob hloov siv cov kev sib nrig sib xyaw ntawm cov kauj los hloov lub voltage. Qhov tseeb, qhov hloov pauv ntawm qhov chaw sib nqus ntawm ib tus inductor tuaj yeem ua rau lwm tus neeg siv hluav taws xob ua kom muaj qhov hluav taws xob tsis nyob hauv qhov sib ze. Cov txiaj ntsig no yog hu ua kev sib koom ua ke (Mutual Inductance).
Thaum ib qho hluav taws xob hloov pauv (V1) tau muab rau lub kauj ntawm thawj winding, txij li qhov siv thiab polarity ntawm qhov hloov tam sim no hloov tas li qhov zoo thiab qhov tsis zoo, tus lej ntawm cov kab sib nqus ntawm lub zog tsim los ntawm lub kauj ntawm thawj winding tseem hloov. Cov. Vim tias qhov kev hloov pauv txuas ntxiv ntawm lub zog hlau nplaum, lwm qhov kawg coil qhov txhab ntawm tib hlau tub ntxhais kawm tau tsim kom muaj lub zog hluav taws xob tiv thaiv quab yuam V2. Tus hloov hluav taws xob tsis tuaj yeem hloov DC lub zog. Qhov no yog vim hais tias lub teb chaw sib nqus yuav tsum hloov pauv kom ua qhov sib txuas ua ke winding tsim ib qho kev yuam kev siab; cov sib nqus flux hla dhau los ntawm cov thawj thiab theem nrab windings ntawm txhua qhov tam sim ntawd yog qhov qub, yog li lub zog hauv lub tshuab hluav taws xob hauv txhua qhov tig ntawm lub kauj muaj tib yam. (dc) Lub teb chaw sib nqus yuav tsis hloov, yog li yuav tsis muaj hluav taws xob tsis muaj dab tsi. Yog tias lub DC hluav taws xob tau tswj rau lub tshuab hloov hluav taws xob, lub tshuab hluav taws xob kuj yuav raug hlawv.
