Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hloov hluav taws xob thiab hloov hluav taws xob hloov hluav taws xob
Lub hauv paus ntsiab lus ntawm kev lag luam zaus transformer yog qhov yooj yim, los ntawm thawj kauj ruam input zaus AC voltage mus rau hauv magnetic teb, los ntawm cov khoom siv hlau nplaum (feem ntau silicon steel ntawv) xa mus rau theem nrab coil induced voltage. Cov zis rau qhov zaus thiab qhov input zaus yog tib yam, qhov voltage raws li cov theem pib ntawm lub kauj hloov dua li qhov txo qhov voltage (yog tias tus naj npawb ntawm cov lem ntawm qhov thib ob yog ntau boost). Raws li cov zis transformer yog alternating tam sim no, thiab feem ntau ntawm cov hluav taws xob circuits siv rau ncaj qha tam sim no, lub transformer tso zis voltage kuj yuav tsum tau rectified, lim, tswj thiab lwm yam circuits, mus rau hauv ib tug kuj smooth thiab ruaj khov voltage rau lub load Circuit Court ib feem ntawm lub ua haujlwm.
Switching fais fab mov tseem yog lub hauv paus ntawm lub transformer tivthaiv, thiab kuj ua raws li cov kev cai ntawm qhov voltage ratio yog sib npaug zos rau cov lem ratio. Tsis zoo li kev lag luam transformers, hloov cov khoom siv hluav taws xob yuav tsum tau ua kom muaj kev ua haujlwm ntau zaus, uas yog, yuav tsum tau hloov qhov tsawg zaus AC voltage rau hauv high-frequency AC voltage, uas yuav tsum tau ntxiv kev tswj Circuit Court kom ua tiav. Vim hais tias lub voj voog yuav tsum muaj DC lub zog ua haujlwm, cov tswv yim AC voltage yuav tsum tau kho thiab hloov mus rau DC voltage ua ntej nws tuaj yeem tswj tau los ntawm Circuit Court tom qab nws. Hauv qab no yog ib qho piv txwv ntawm kev siv xov tooj ntawm tes charger Circuit Court luv luv kom nkag siab txog kev ua haujlwm ntawm kev hloov hluav taws xob.
Tawm tswv yim 220V AC voltage tom qab rectification thiab lim, yuav dhau los ua 310V DC voltage (uas yog, 220V AC voltage ncov), cov nram qab no yuav tsum tau tig DC mus rau high-frequency alternating tam sim no. Xav tig qhov hluav taws xob no mus rau qhov sib txawv ntawm qhov siab, txoj hauv kev yooj yim tshaj plaws yog siv qhov hloov pauv, kom qhov hloov pauv sai sai thiab kaw, kom lub zog DC mus rau hauv lub siab ceev pulse DC voltage, kom ua tiav qhov kev hloov pauv yog ib transistor. Transistors, suav nrog feem ntau siv cov transistors thiab cov raj xa hluav taws xob, thiab lwm yam, ob qho khoom siv no tuaj yeem siv los ua hluav taws xob hloov hluav taws xob, uas yog, los ntawm kev tswj hluav taws xob ntawm tus pin (lub hauv paus ntawm lub transistor nrog rau lub rooj vag ntawm lub teb cov nyhuv. raj), koj tuaj yeem ua rau lwm tus pins kom ua tiav qhov kev tswj hwm ntawm kev tawm.
Nrog rau qhov hloov pauv, tom ntej no yuav tsum tau tswj cov hloov hluav taws xob, lub luag haujlwm ntawm lub Circuit Court no yog tso tawm cov hluav taws xob hloov hluav taws xob kom tswj tau lub raj xa hluav taws xob rau thiab tawm, qhov Circuit Court no hu ua oscillator circuit. Qhov Circuit Court no hu ua oscillation circuit. Switching fais fab mov oscillation Circuit Court yog muab faib ua ntau hom, tsis hais ib tug twg, lub luag hauj lwm yog muab kev tswj cov teeb liab rau lub switching tube. Tom qab kev tswj Circuit Court tswj, lub input voltage los ntawm qhov tsawg zaus hloov tam sim no mus rau hauv high-frequency pulsed DC voltage, input mus rau lub transformer rau kauj ruam-down, transformer tso zis voltage kuj yuav rectified. Cov zis hluav taws xob los ntawm lub tshuab hloov pauv kuj tau kho thiab lim rau hauv DC cov zis, uas yog muab rau cov khoom thauj. Qhov sib txawv nrog rau kev lag luam zaus transformer yog qhov hloov hluav taws xob hloov pauv kuj muaj ib qho ntxiv ntawm qhov ntsuas hluav taws xob hluav taws xob, uas yuav tso tawm qhov hluav taws xob hluav taws xob los ntawm kev kuaj pom thiab tawm tswv yim rau lub transformer thawj tswj Circuit Court rau kev tswj voltage, uas ua rau lub zog hloov. mov Qhov no ua rau kev ruaj ntseg ntawm cov zis hluav taws xob ntawm cov khoom siv hluav taws xob hloov tau zoo dua qub, thiab tuaj yeem muaj ntau yam ntawm cov khoom siv hluav taws xob. Yog li cov txheej txheem ua haujlwm ntawm kev hloov hluav taws xob yog los ntawm AC - DC, DC - AC, thiab tom qab ntawd los ntawm AC - AC
DC - AC, thiab tom qab ntawd los ntawm AC - DC ob peb txheej txheem kom ua tiav.
