Hloov cov khoom siv hluav taws xob yog ua raws li kev siv hluav taws xob ntau zaus hloov pauv hloov tsis ruaj khov thiab tsis sib haum xeeb (AC) mus rau qhov tsis tshua muaj hluav taws xob tam sim no (DC) qhov xav tau los ntawm lwm yam khoom siv.Qhov tseeb, qhov hloov hluav taws xob hloov pauv tuaj yeem hais tau tias yog ib qho khoom siv kho plawv rau lwm yam khoom siv, thiab nws cov nyhuv me me heev.
Lub ntsiab lus tseem ceeb ntawm kev hloov fais fab mov: nce lub zog ntawm cov khoom siv hluav taws xob raws li txoj hauv kev xws li nce lub zog tso zis, yog li txo qhov loj thiab qhov hnyav ntawm lub zog transformer.Qhov txiaj ntsig tseem ceeb ntawm kev hloov hluav taws xob hloov pauv yog txhawm rau txhim kho kev ua haujlwm siab ntawm electromagnetic zog hloov dua siab tshiab.Qhov kev ua haujlwm siab ntawm PC fais fab mov yog 70% -75%, thaum lub zog ua haujlwm siab ntawm cov khoom siv hluav taws xob sib xws tsuas yog kwv yees li 50%.
Qhov kev ntseeg siab ntawm qhov tso zis hluav taws xob yog nyob rau hauv kev hloov pauv ntawm pulse dav, uas yog hu ua pulse width modulation PWM.
Cov ntsiab lus ua haujlwm ntawm lub zog hloov hluav taws xob yog qhov yooj yim.
Thaum cov khoom siv hluav taws xob hauv nroog nkag mus rau lub zog hluav taws xob, cov khoom siv hluav taws xob ntau zaus thiab cov hluav taws xob cuam tshuam tau raug tshem tawm thawj zaug raws li cov choke coil thiab capacitor filtering ntaus ntawv, thiab tom qab ntawd lub high-voltage DC fais fab mov yog tau raws li lub rectifier thiab filtering ntaus ntawv.Tom qab ntawd ib feem ntawm qhov kev sib txuas lus siab yog lim tawm, kom cov txheeb ze uas tsis tshua muaj hluav taws xob DC fais fab mov ntawm cov khoom siv sib txuas yog qhov kawg tso tawm.
