txhawm rau txhim kho kev nyab xeeb ntawm cov tshuab hluav taws xob thiab cov teeb pom kev zoo, ntau zaus nws raug pom zoo kom siv cov roj teeb uas muaj qhov hluav taws xob qis dua li siv hauv cov qauv network (220 V). Feem ntau, xws li teeb pom kev zoo yog npaj rau hauv qab daus, chav dej, cellars thiab lwm qhov chaw ntub dej. Rau cov laj thawj no, niaj hnub no lub teeb hluav taws xob halogen tau siv, qhov kev khiav hauj lwm qhov hluav taws xob yog 12 V. Rau lub teeb hluav taws xob ntawm hom no, cov khoom siv xws li hluav taws xob transformer yog siv. Cov cuab yeej no tuaj yeem hloov pauv qhov hluav taws xob tseem ceeb ntawm 220 V rau hauv 12 V (zoo rau kev ua haujlwm ntawm lub teeb halogen).
Yog tias koj saib ntawm lub tshuab hluav taws xob, koj tuaj yeem nkag siab tias nws cov khoom siv sab nraud yog qhov yooj yim heev. Nws yog ib lub thawv me me los yog hlau, los ntawm qhov xaus ntawm plaub lub xov hlau:ob lub khoom nkag (labeled 220V) thiab ob qhov tawm (labeled 12V).
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov cuab yeej xws li hluav taws xob transformer yog qhov yooj yim heev. Kev tswj kev ci ntsa iab yog ua los ntawm kev siv thyristor controllers (lawv hu ua dimmers). Cov regulators no nyob rau ntawm high voltage (input) sab. Ntau yam khoom siv xws li hluav taws xob transformers tuaj yeem txuas nrog ib qho dimmer tib lub sijhawm. Lawm, muaj cov qauv kev hloov pauv ntawm cov khoom siv zoo li no yam tsis muaj kev tswj hwm. Ib qho tseem ceeb yuav tsum nco ntsoov: lub tshuab hluav taws xob hluav taws xob yuav tsum tsis txhob pib yam tsis muaj kev thauj khoom. Koj yuav tsum xyuam xim rau lub hwj chim. Cov tuam txhab lag luam niaj hnub tsim hluav taws xob hloov hluav taws xob nrog lub zog ntawm 60 txog 250 W.
Lub cuab yeej nws tus kheej yog lub laub rub tus kheej oscillator ntawm ib nrab choj Circuit Court. Ob txhais caj npab ntawm tus choj no yog transistors. Lwm ob txhais tes yog capacitor. Yog vim li ntawd, tus choj no hu ua ib nrab choj. Ib tug voltage yog siv rau ib kab pheeb ces kaum, uas yog rectified los ntawm ib tug diode choj. Lub load txuas nrog rau lwm kab pheeb ces kaum. Txhawm rau tswj kev ua haujlwm ntawm transistor kab pheeb ces kaum, cov windings ntawm cov lus tawm tswv yim transformer txuas nrog hauv lawv lub voj voog. Qhov voltage rectified los ntawm tus choj yuav tsub lub capacitor, thiab thaum lub voltage ntawm lub capacitor mus txog qhov txwv, lub dinistor yuav qhib thiab ib tug mem tes yuav raug generated uas pib lub converter tam sim no.
Ib yam khoom xws li hluav taws xob hloov hluav taws xob muaj ntau yam tsis tuaj yeem lees paubtsim nyog. Ua ntej, peb yuav tsum hais txog qhov me me tag nrho qhov ntev thiab qhov hnyav. Qhov no muab lub sijhawm zoo rau nruab lub tshuab hluav taws xob hluav taws xob zoo nyob txhua qhov chaw (txawm tias nyob rau hauv qhov chaw nyuaj-mus txog). Qee lub teeb pom kev zoo niaj hnub no uas tau tsim tshwj xeeb los ua haujlwm nrog cov teeb halogen twb muaj ob peb lub tshuab hluav taws xob ua ntej ua ntej. Cov tswv yim zoo li no tau pom lawv daim ntawv thov hauv lub neej niaj hnub, piv txwv li, hauv kev tsim kho ntawm chandelier. Cov tshuab hluav taws xob tam sim no tau nruab rau hauv cov rooj tog zaum, piv txwv li, hauv cov txee, los tsim teeb pom kev rau hangers thiab txee.
Tab sis cov no nyob deb ntawm txhua qhov chaw ntawm kev siv cov cuab yeej xws li hluav taws xob transformer. Piv txwv li, muaj qee qhov kev txhim kho uas feem ntau tsis tas yuav qhib rooj plaub, txawm li cas los xij, lawv tso cai rau koj los tsim lub zog hloov hluav taws xob los ntawm hluav taws xob hloov hluav taws xob (UPS).
