Dab tsi yog Qhov Kev Hloov Hluav Taws Xob? Hloov cov khoom siv hluav taws xob yog tsim los rau kev ua haujlwm siab thiab me me. Lawv suav nrog hloov regulator los hloov hluav taws xob kom zoo. Hloov cov khoom siv hluav taws xob DC tswj cov zis hluav taws xob los ntawm cov txheej txheem hu ua pulse width modulation (PWM).
Lub ntsiab lus ntawm kev hloov hluav taws xob yog dab tsi?
Ib hom hloov hluav taws xob yog lub zog hloov hluav taws xob uas siv cov khoom siv hloov pauvxws li MOSFETs uas tsis tu ncua tig thiab tawm ntawm qhov siab; thiab lub zog cia khoom xws li cov capacitors thiab inductors los muab lub zog thaum lub sijhawm tsis ua haujlwm ntawm lub tshuab hloov pauv.
Lub hauv paus ntsiab lus ntawm cov khoom siv hluav taws xob hloov pauv yog dab tsi?
Txoj Cai Ua Haujlwm ntawm SMPS Kev Siv Hluav Taws Xob
Nws tuaj yeem nce lossis txo qhov tso zis hluav taws xob kom tswj tau cov zis tas li tsis hais txog kev hloov pauv hauv kev thauj khoom. Qhov kev muaj peev xwm dual no ua rau nws muaj txiaj ntsig zoo dua li kev tswj hwm cov kab hluav taws xob, uas tuaj yeem tswj hwm cov zis tawm (uas yog, lawv tsuas tuaj yeem txo qhov voltage, tsis nce nws).
Cov khoom siv hluav taws xob hloov pauv tau zoo npaum li cas?
Kev tswj qhov hluav taws xob hauv kev hloov hluav taws xob yog tsim yam tsis muaj cua sov ntau dhau. SMPS kev ua tau zoo tuaj yeem siab li 85% -90%. Kev siv yooj yim. Ntxiv windings tuaj yeem muab ntxiv rau qhov hloov hluav taws xob los muab ntau tshaj ib qhov tso zis voltage.
Ib qho hloov hluav taws xobzoo dua?
Lub zog hloov pauv txhais tau tias ua haujlwm ntau duavim yog qhov hloov pauv ntau zaus, ua rau nws siv me me, tsis tshua muaj nqi hluav taws xob ntau zaus thiab sib dua, tsawg dua- kim lim cov Cheebtsam. Hloov cov khoom siv hluav taws xob muaj cov khoom siv tag nrho, yog li feem ntau kim dua.

Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Hauv cov khoom siv hluav taws xob tsim hluav taws xob?
Nyob hauv cov khoom siv hluav taws xob tsim hluav taws xob, xws li hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib qho hlau xws li Nichrome Nichrome Nichrome (tseem hu ua NiCr, nickel-chromium lossis chromium-nickel) yog ib tsev neeg ntawm cov alloys ntawm npib tsib xee, chromium, thiab feem ntau hlau (thiab tejzaum nws muaj lwm yam) feem ntau siv raws li cov hlau tsis kam, cov khoom cua sov hauv cov khoom xws li toasters thiab qhov chaw tso cua sov, hauv qee qhov
Dab tsi yuav tsum muaj qhov hloov hluav taws xob hloov hluav taws xob nyob twj ywm?
Feem ntau cov alternators uas them kom zoo yuav tsum tsim qhov voltage ntawm kwv yees 13.8 txog 14.2 volts ntawm qhov tsis ua haujlwm nrog lub teeb thiab cov khoom siv tawm. Nco ntsoov xa mus rau cov chaw tsim khoom tsheb cov lus qhia tshwj xeeb.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
