Yig fluorescent teeb ua tau hauj lwm tsuas nrog rau hauv ballasts. Cov pab kiag li lawm yog tsim rau flattening tam sim no. Ntaub ntawv hais txog cov hluav taws xob ballast (Scheme, kho thiab kev twb kev txuas), muaj ib tug ntau. Ua ntej, txawm li cas los, nws yog ib qho tseem ceeb kawm lub twj paj nruag ntaus ntawv.

Tus txheem qauv muaj xws li ib tug transformer, Shockley diode thiab ib tug transistor. Heev feem ntau, lub fuse ntsia rau lub system ntawm kev tiv thaiv. Tshwj xeeb raws raug muab rau lub kev twb kev txuas ntawm lub teeb. Tsis tas li ntawd, tus ntaus ntawv outputs yog uas hluav taws xob yog nkag.

hauv paus ntsiab lus ntawm cov lag luam

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub tshuab hluav taws xob ballast yog ua nyob rau hauv lub tam sim no pom. Tag nrho cov txheej txheem pib tom qab lub hwj huam mov mus rau lub channel. Ntxiv mus, lub lag luam nkag mus rau daig caj pas. Rau ntawm no theem, cov limiting zaus ntawm tus dais yog significantly txo. Thaum zoo li no tsis zoo kuj Circuit Court, on qhov tsis tooj, muaj zog. Tom ntej no, tam sim no kis tau los ntawm thiab yog teeb meem rau dynistor transistor. Raws li ib tug tshwm sim, tam sim no hloov dua siab tshiab yog ua. Nws thiaj li, lub voltage kis tau los ntawm ib tug transformer yam ntau yam rau fluorescent teeb.

Qauv diode hom

Qauv diode hom yog tam sim no xam tau tias yog cov nyiaj txiag. Nyob rau hauv cov ntaub ntawv no tsuas transformers yog siv down hom. Ib txhia manufacturers nruab ib qhib hom transistors. Vim li no cov txheej txheem txo lub zaus nyob rau hauv lub Circuit Court yog tsis ntse heev. ob capacitors yog siv los tswj cov zis voltage. Yog hais tias peb xav txog qhov tam sim no cov qauv ntawm cov ballasts, muaj dynistors kev khiav hauj lwm hom. Yav tas los, lawv tau hloov nrog cov pa converters.

ob-lug ua qauv

Qhov no hom ntawm hluav taws xob ballast Circuit Court rau ib tug fluorescent teeb raws los ntawm lwm yam qauv nyob rau hauv uas nws yuav siv li ib tug. Yog li, tus neeg siv yuav muaj peev xwm mus kho cov qhov tso zis voltage chaw. Transformers yog siv nyob rau hauv ib tug ntau yam ntawm pab kiag li lawm. Yog hais tias peb xav txog cov qauv, muaj yog ntsia, kom txhob muaj muaj sib npaug. Txawm li cas los, ib leeg-theem configuration yog tsis inferior mus rau lawv nyob rau hauv lub tsis.

Tag nrho cov capacitors nyob rau hauv lub Circuit Court muab nyob rau hauv lub ob qauv. Tsis tas li ntawd, muab ob npaug rau-twb circuits ntawm hluav taws xob ballasts txuag teeb muaj xws li throttle, uas yog teem rau cov qhov tso zis raws. Transistors qauv yog tsim tsuas capacitive. Nyob rau hauv kev ua lag luam lawv yog sawv cev los ntawm ob DC thiab AC hom. Lub fuses nyob rau hauv lub pab kiag li lawm yog tsis tshua muaj siv. Txawm li cas los, yog hais tias tus Circuit Court yog teem rau lub thyristor rectification, ces tsis txhob ua tsis tau nws.

Nyob rau hauv cov ntaub ntawv no, lub transistors siv, feem ntau yog qhib hom. Muaj ntau cov kws tshwj xeeb lawv muaj nuj nqis rau lub siab tam sim no conductivity. Txawm li cas los, rau lub qub lag luam ntawm lub ntaus ntawv nws yog ib qho tseem ceeb heev qhov zoo dynistor.

kev khiav hauj lwm analogs feem ntau yog siv mus rau kauj ruam-down transformers. Ua ntej ntawm tag nrho cov, lawv yog prized rau lawv compactness thiab hluav taws xob ballasts qhov no yog ib tug tseem ceeb kom zoo dua. Nyob rau hauv tas li ntawd, lawv txawv nyob rau hauv txo rhiab heev, thiab me me swb nyob rau hauv lub network rau lawv scary.

Kev siv cov vector transistors

Vector transistors nyob rau hauv hluav taws xob ballasts yog siv heev tsis tshua muaj. Txawm li cas los, tam sim no ua qauv yeej tseem muaj. Yog hais tias peb tham txog cov yam ntxwv ntawm lub Cheebtsam, nws yog ib qho tseem ceeb kom nco ntsoov tias qhov tsis zoo kuj muaj cov kev kom lawv nyob rau theem ntawm 40 ohms. Txawm li cas los, congestion lawv tiv zoo nkauj phem. Nyob rau hauv cov ntaub ntawv no plays ib qho tseem ceeb luag hauj lwm parameter tso zis voltage.

Yog hais tias peb tham txog cov transistors, ces rau cov transformers yog tsim orthogonal hom. lawv yog cov nyob rau kev ua lag luam yog kim heev, tab sis lub hwj chim noj yog tsis tshua muaj tsis tshua muaj nyob rau hauv tus qauv. Nyob rau hauv cov ntaub ntawv no, cov qauv nrog vector transformers ho poob compactness competitors nrog txo configurations.

Scheme ib nrog tus maub los

Hauv ballast rau fluorescent teeb nrog ib maub los yog yooj yim heev. Nyob rau hauv cov ntaub ntawv no, cov kauj ruam-down transformers yog siv hom. Tam sim ntawd muaj ob capacitors nyob rau hauv lub system. Yuav kom txo tau qhov tsis pub tshaj zaus ntawm tus qauv muaj dynistor. Lub transistor siv nyob rau hauv lub tshuab hluav taws xob ballast kev khiav hauj lwm hom. Tsis zoo kuj nws yog tau withstand tsawg kawg yog 40 ohms. Lub tso zis transistors nyob rau hauv tus qauv ntawm no hom yuav luag yeej tsis siv. Txawm li cas los, lub fuses yog ntsia, thiab yog hais tias lub network failures lawv pab zoo heev.

Kev siv ntawm tsawg zaus chiv

Lub txhais rau cov tshuab hluav taws xob ballast rau fluorescent teeb ntsia tau rau hauv lub rooj plaub thaum lub tsis zoo kuj muaj cov Circuit Court yog ntau tshaj 60 Ohm. Lub load los ntawm cov transformer nws yub zoo heev. Lub fuses yog ntsia nyob rau tib lub sij hawm yog tsis tshua muaj heev. Transformers rau cov qauv ntawm cov hom yog tsuas yog siv vector. Nyob rau hauv cov ntaub ntawv no, kom txhob muaj muaj sib npaug tsis muaj peev xwm tiv nrog ib tug ntse dhia txwv moos.

Ncaj qha dynistors qauv ntsia nyob ze ntawm lub txhawm chim. Los ntawm compactness, hluav taws xob ballasts yog heev txawv. Nyob rau hauv cov ntaub ntawv no, ntau npaum li cas nyob rau hauv lub siv Cheebtsam ntawm lub ntaus ntawv. Yog hais tias peb tham txog cov qauv nrog regulators, lawv yuav tsum tau ib tug ntau ntawm qhov chaw. Lawv yog cov tseem muaj peev xwm ua hauj lwm nyob rau hauv hluav taws xob ballasts tsuas yog ob tug capacitors.

Qauv tsis muaj tus regulators yog heev compact, tab sis lub transistors tsuas yog orthogonal hom yuav tsum tau siv. Lawv tsiag ntawv los ntawm zoo conductivity. Txawm li cas los, nws yuav tsum tau borne nyob rau hauv lub siab tias cov ntaub ntawv hluav taws xob ballasts mus rau ib tug buyer ua lag luam yuav raug nqi dearly.
