Raws li kev siv thev naus laus zis, kev thov rau cov khoom siv hluav taws xob txuas ntxiv mus ntxiv. Ua kom tau raws li cov kev xav tau no, kev hloov pauv ntau zaus DC cov khoom siv hluav taws xob tau dhau los ua cov thev naus laus zis tseem ceeb. Los ntawm cov khoom siv sib txuas lus mus rau cov cuab yeej kho mob, los ntawm kev tswj hwm kev lag luam mus rau tus kheej hluav taws xob,high zaus hloov DC fais fab movtau permeated txhua yam ntawm peb lub neej. Yog li, dab tsi tiag tiag yog qhov hloov pauv DC lub zog loj, thiab nws ua haujlwm li cas?
Ua ntej, cia peb nkag siab nws cov hauv paus ntsiab lus. Lub siab zaus hloov DC fais fab mov yog lub zog hluav taws xob uas tuaj yeem hloov cov tswv yim hloov tam sim no (AC) lub zog rau hauv qhov hluav taws xob ncaj qha tam sim no (DC) qhov hluav taws xob. Piv nrog rau cov kev cai linear regulators,high-frequency switching DC fais fab movmuab kev ua haujlwm siab dua thiab me me, ua rau lawv siv dav hauv ntau yam khoom siv hluav taws xob.
Kev ua haujlwm ntawmhigh-frequency switching DC fais fab movFeem ntau yog ua los ntawm ob lub ntsiab lus tseem ceeb: kev hloov regulator thiab tswj Circuit Court. Lub switching regulator tswj cov zis voltage ntawm lub hwj chim mov siv high-frequency switching li (xws li MOSFETs), thaum lub tswj Circuit Court saib xyuas cov zis voltage thiab kho lub switching regulator kom muaj ib tug ruaj khov tso zis voltage.
Hauv cov txheej txheem no, cov tswv yim AC lub zog yog thawj zaug kho rau DC lub zog los ntawm lub tshuab hluav taws xob, tom qab ntawd tswj hwm los ntawm kev hloov hluav taws xob, thiab ruaj khov los ntawm kev tswj xyuas Circuit Court. Cov txheej txheem hloov hluav taws xob ua tau zoo no ua rauhigh-frequency switching DC fais fab movkom tsis tsuas yog muab lub zog ruaj khov tso tawm tab sis kuj ua tiav lub zog ua haujlwm siab hloov pauv raws li qhov sib txawv load.
Cov kev siv ntawmhigh-frequency switching DC fais fab movmuaj ntau haiv neeg. Hauv kev lag luam ntawm cov khoom siv sib txuas lus, lawv tuaj yeem muab lub zog ruaj khov thiab txhim khu kev qha kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv sib txuas lus. Hauv cov cuab yeej siv computer, lawv tuaj yeem muab kev txhawb zog ruaj khov rau cov khoom xws li CPUs thiab cov ntawv teev lus. Hauv thaj chaw kho mob, lawv tuaj yeem muab cov khoom siv hluav taws xob zoo rau cov khoom siv kho mob kom ntseeg tau tias kev kho mob zoo.
Hauv cov ntsiab lus,high-frequency switching DC fais fab movyog cov khoom siv hluav taws xob zoo, ruaj khov, thiab txhim khu kev qha lub zog hloov dua siab tshiab uas tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Nrog rau kev txhim kho thev naus laus zis tsis tu ncua, nws ntseeg tau tias kev hloov pauv ntau zaus DC cov khoom siv hluav taws xob yuav ua lub luag haujlwm tseem ceeb dua yav tom ntej, ua kom yooj yim dua thiab muaj peev xwm rau peb lub neej.
