Amagetsi ballast dera nyali fulorosenti. Mfundo zikugwira ntchito kwa nyali fulorosenti

Ndalama nyali fulorosenti ndi kugwira ntchito kokha ndi ballasts amagetsi. zipangizozi anapangidwa kuti flattening pano. Information za ballast zamagetsi (chiwembu, kukonza ndi kugwirizana), pali zambiri. Koma poyamba, ndikofunika kuphunzira chipangizo choimbira.

Muyezo chitsanzo chikuphatikizapo thiransifoma, Shockley diode ndi transistor. Nthawi zambiri, ndi lama fuyusi anaika pa dongosolo la chitetezo. njira apadera anapatsa kugwirizana nyali. Komanso zotuluka chipangizo ndi amene magetsi umaperekedwa.

Mfundo ntchito

Mfundo ntchito ballast a pakompyuta inamangidwa pa kusintha panopa. The ndondomeko lonse limaphwanya pambuyo magetsi kwa njira. Komanso, ntchito umalowa kutsamwa. Pa nthawi imeneyi, a Kuchepetsa pafupipafupi chipangizo ali kwambiri yafupika. Pamene izi kukana dera zoipa M'malo mwake, kuchuluka. Kenako, panopa umadutsa ndi zinachitika pa dynistor transistor. Chifukwa, kutembenuka panopa imagwiridwa. M'kupita kwa nthawi, voteji umadutsa ndi thiransifoma anakhumba osiyanasiyana kwa nyali fulorosenti.

Chitsanzo diode mtundu

Mitundu zitsanzo diode panopa ankaona bajeti. Pankhaniyi tiransifoma yekha ntchito pansi mtundu. Anthu ena opanga kukhazikitsa lotseguka mtundu transistors. Chifukwa ndondomekoyi kuchepa pafupipafupi mu dera si lakuthwa kwambiri. capacitors awiri ntchito ziziyenda linanena bungwe voteji. Ngati tikambirana zitsanzo panopa ballasts, pali dynistors opaleshoni mtundu. Poyamba, iwo anali m'malo ndi converters ochiritsira.

zitsanzo awiri lofotokozera

Mtundu wa ballast dera pakompyuta kwa nyali fulorosenti isiyana ndi zitsanzo zina kuti akugwiritsa ntchito Mtsogoleri. Choncho, wosuta amatha kusintha kolowera linanena bungwe voteji. Transformers ntchito zosiyanasiyana zipangizo. Ngati tikambirana chitsanzo wamba, pali anaika, kuchepetsa zofanana. Komabe, osakwatiwa-gawo kasinthidwe si wolephera iwo mu magawo.

capacitors onse dera operekedwa mu zitsanzo ziwiri. Komanso, awiri inatha madera a ballasts pakompyuta kupulumutsa nyali monga fulumizitsa, amene anapereka njira linanena bungwe. Transistors zitsanzo ali oyenera capacitive yekha. Mu msika iwo amakhala ndi onse DC ndi AC mtundu. The mafyuzi mu zipangizo kawirikawiri ntchito. Komabe, ngati dera chikuyambika kwa thyristor rectification, ndiye musati kuchita popanda izo.

ballast circuitry "ballasts" 18W

Izi pakompyuta ballast dera nyali fulorosenti chikuphatikizapo tsatane-pansi thiransifoma, ndi mitundu iwiri iwiri ya capacitors. Transistor chitsanzo chimodzi chokha anapereka. Wachisoni kukana ndi kuzilepheretsa munthu pazipita 33 ohms. amaona zachilendo kwa zipangizo za mtundu uwu. Komanso pakompyuta ballast dera 18W kumaphatikizapo inductor limene lili pamwambapa thiransifoma lapansi. Shockley diode kwa akatembenuka panopa Akutsatira yodziyimira payokha mtundu. Kutsitsa wotchi kumachitika mwa tetrode a. mchitidwe ili pafupi fulumizitsa lapansi.

Ballast "EPRA" 2h18 W

Anati pakompyuta ballast 2h18 (chiwembu pansipa) Amakhala wa transistors linanena bungwe, ndipo mwatsatane-pansi thiransifoma. Ngati ife kulankhula za transistor, ndi Pankhaniyi anapereka mtundu lotseguka. Okwana pali capacitors awiri mu dera la. chiwembu wina mu ballasts pakompyuta "EPRA" 18 W ali fulumizitsa limene lili pansi thiransifoma lapansi.

Capacitors ndi muyezo anapereka pafupi njira. The ndondomeko kutembenuka ikuchitika mwa kutsitsa koloko pafupipafupi chipangizo. kukhazikika Voteji amaperekedwa Pankhaniyi chifukwa cha dinistorov khalidwe. ngalande zonse chitsanzo, pali awiri.

ballast circuitry "ballasts" 4x18 W

Izi pakompyuta ballast 4x18 (chiwembu pansipa) kumaphatikizapo capacitors inverting mtundu. mphamvu zawo ziri chimodzimodzi 5 PF. Pankhaniyi, mthunzi kukana chizindikiro mu ballast a pakompyuta adza kwa ohms 40. M'pofunikanso kutchula kuti fulumizitsa mu kasinthidwe zokambidwa ndi pansi dinistorov. Transistor chitsanzo ichi ali limodzi. A thiransifoma kwa kuthetsa panopa ntchito pansi mtundu. Zimamuchulukira ndi waluso kupirira zopezera lalikulu. Komabe, lama fuyusi akadali anaika mu dera la.

ballast kuyenda panyanja

Pakompyuta ballast kuyenda panyanja (chiwembu pansipa) chikuphatikizapo unijunction transistor. Komanso, mosiyana ndi chitsanzo ndi pamaso pa ulamuliro wapadera. Atatero, wosuta akhoza kusintha kolowera wa voteji linanena bungwe. Ngati ife kulankhula za thiransifoma, izo amaperekedwa mu unyolo pansi mtundu. Malowa ali pamtunda pafupi fulumizitsa ndi pa mbale. The resistor kwa pempheroli chikufanana capacitive mtundu.

Pankhaniyi, pali capacitors awiri. The loyamba lili pafupi thiransifoma lapansi. Kuchepetsa mphamvu ndi wofanana 5 PF. A capacitor wachiwiri unyolo ili pansi transistor lapansi. mphamvu ndi wofanana kwambiri monga 7 PF, ndi kukana zoipa pazipita izo chingathe kupirira pa ohms 40. Lama fuyusi deta ya ballasts pakompyuta si ntchito.

pakompyuta ballast dera transistors EN13003A

pakompyuta ballast dera nyali fulorosenti ndi transistors EN13003A ndi lero zachilendo. Zitsanzo zilipo, zambiri popanda amazilamulira ndi a kalasi ya zipangizo bajeti. Komabe, zipangizo amatha mpaka nthawi yaitali, ndipo mafyuzi. Ngati ife kulankhula za tiransifoma, iwo ali oyenera okha pansi mtundu.

Anatipatsa transistor mu dera la pafupi fulumizitsa lapansi. dongosolo chitetezo zitsanzo izi makamaka ntchito muyezo. zipangizo Contact dinistorov ndiotetezedwa. Komanso mu pakompyuta ballast dera 13003 chikuphatikizapo capacitor omwe kaŵirikaŵiri anaika ndi mphamvu za 5 PF.

Ntchito tiransifoma sitepe-pansi

amagetsi ballast dera nyali fulorosenti ndi thiransifoma sitepe-pansi mafilimu komanso owongolera voteji. Mu nkhani iyi, transistors ntchito, zambiri lotseguka mtundu. akatswiri ambiri ndi ofunika kwambiri kwa mkulu madutsidwe panopa. Komabe, ntchito yachibadwa chipangizo ndikofunika Mkhalidwe dynistor.

analogs zikugwira ntchito kawirikawiri amagwiritsidwa ntchito mwatsatane pansi tiransifoma. Choyamba, iwo nsombazi chifukwa cha compactness awo ndi ballasts pakompyuta ili ndi mwayi kwambiri. Komanso, iwo amasiyana wotsikirapo tilinazo, ndi zolephera yaing'ono maukonde kwa iwo wowopsa.

Ntchito transistors vekitala

Vekitala transistors mu ballasts pakompyuta ntchito kwambiri kawirikawiri. Komabe, zitsanzo panopa alipobe. Ngati ife kulankhula za maonekedwe a zigawo zikuluzikulu, ndikofunika kudziwa kuti kukana zoipa njira kuwasunga pa mlingo wa ohms 40. Komabe, kuchulukana kupirira wokongola zoipa. Pankhaniyi amasewera yofunika chizindikiro linanena bungwe voteji.

Ngati ife kulankhula za transistors, ndiye kuti tiransifoma awa ali oyenera kwambiri orthogonal mtundu. ali pa msika ndi mtengo ndithu, koma mowa mphamvu ndi otsika kwambiri mu zitsanzo za. Pankhaniyi, chitsanzo ndi tiransifoma vekitala kwambiri kutaya mpikisano compactness ndi masanjidwe kuchepetsa.

Chiwembu yofunika ndi Mtsogoleri wa

Pakompyuta ballast chifukwa nyali fulorosenti ndi yofunika Mtsogoleri ndi wosavuta. Mu nkhani iyi, tiransifoma sitepe-pansi ntchito mtundu. Pomwepo ndi capacitors awiri mu dongosolo. Kuchepetsa malire pafupipafupi chitsanzo ali dynistor. The transistor ntchito pakompyuta ballast mtundu opaleshoni. Wachisoni kukana ndi kuzilepheretsa osachepera 40 ohms. The transistors linanena bungwe mu zitsanzo za mtundu uwu pafupifupi konse ntchito. Komabe, mafyuzi amene anaika, ndi ngati zolephera maukonde amathandiza kwambiri.

Ntchito akapsa otsika-pafupipafupi

The choyambitsa kwa ballast pakompyuta kwa nyali fulorosenti anaika mu nkhani imene kukana zoipa dera ali wamkulu kuposa 60 Ohm. Katundu ku thiransifoma iye akuwombera bwino. mafyuzi The amene anaika pa nthawi yomweyo chosowa kwambiri. Transformers kwa zitsanzo za mtundu uwu akugwiritsidwa kokha vekitala. Pankhaniyi, kuchepetsa zofanana amalephera kupirira lakuthwa kulumpha malire koloko.

Mwachindunji dynistors zitsanzo anaika pafupi Kukonda Chuma ndi. Ndi compactness, ballasts pakompyuta zosiyana. Pankhaniyi, zambiri zimadalira ntchito chipangizo. Ngati ife kulankhula za zitsanzo ndi owongolera, iwo amafuna kwambiri m'mlengalenga. Iwo angathe kugwira ntchito mu ballasts pakompyuta capacitors awiri okha.

Chitsanzo popanda owongolera ndi yaying'ono kwambiri, koma transistors okha orthogonal mtundu angagwiritsidwe ntchito. Iwo yodziwika ndi madutsidwe wabwino. Komabe, tiyenera adzanyamula kukumbukira kuti deta ballasts kompyuta msika wogula ndi ndalama kwambiri.
