Faib cov AC voltage los ntawm square root ntawm 2 mus nrhiav tus DC hluav taws xob. Txij thaum ib AC Lub zog hluav taws xob xa hluav taws xob hauv cov nthwv dej sib hloov, DC voltage yuav qis dua ib zaug koj hloov nws. Sau cov formulaV AC /√(2) thiab hloov V AC nrog rau AC voltage koj pom nrog koj lub multimeter.
Ua raws li qhov xav tau, vim li cas peb hloov AC rau DC?
Peb xav tau Konvertiere AC in HLB vim yog cov ntsiab lus hauv qab no: AC Cov cim tsis tuaj yeem khaws cia thiab DC lub hwj chim lossis cov teeb liab tuaj yeem khaws cia. Yog li khaws cov hluav taws xob hluav taws xob peb xav tau hloov nws rau hauv DC . AC canbe thauj mus deb heev vim nws yog zaus thiab dc ua thauj tsis tau li dc ua muaj zerofrequency.
Tsis tas li, AC fais fab sib npaug li DC fais fab li cas? Summary: Watts out DC = 75% mus rau 90% ntawm AC Watts hauv, feem ntau. Saib hauv qab no: Ntawm 100% efficiency ADC Wattsout = AC Watts nyob rau hauv. Zog yog 'conserved thiab lub zog = Wattsx lub sij hawm.
Piv txwv li, puas lub capacitor hloov AC rau DC?
A capacitor tsis tuaj yeem NTAWM nws tus kheej hloov ib AC hauv a DC , tab sis ib qho zoo synchronized hloov, uas hla lub ncov xaiv thiab tsis lees txais qhov chaw ntawm lub AC waveform, xav ua nws. Circuit Court voltage ua tsis hloov nrog zaus txawm tias qhov reactance ntawm cov cov capacitordoes.
DC rau AC converters ua haujlwm li cas?
Koj xav tau ib tug ntaus ntawv uas yuav hloov lub DC power los ntawm lub roj teeb rau AC lub zog uas tuaj yeem ua haujlwm ntawm lub tub yees lub compressor. Qhov no DC rau AC converter hu ua inverter . Nws yog ib qho yooj yim los hloov AC tam sim no DC - txhua yam koj xav tau ua yog pub tam sim no los ntawm diode, uas tsuas yog dhau tam sim no hauv ib qho kev taw qhia.
