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.
