Nrog kev txhim kho cov thev naus laus zis thev naus laus zis, lub teeb hluav taws xob txuag hluav taws xob zoo nrog cov hluav taws xob hluav taws xob thiab lub teeb nruab hnub nrig raj ntsiag to nkag mus rau ntau txhiab tsev neeg. Nws tau pom tias hluav taws xob ballasts muaj ob qhov tsis zoo: (1) triode (xws li C2482, thiab lwm yam) yog ib qho yooj yim rau kev puas tsuaj, yog li lub neej ntawm lub teeb txuag hluav taws xob yog luv heev; (2) Qhov qis zog, qhov kev txuag hluav taws xob tsis zoo.
Cov hluav taws xob hluav taws xob hluav taws xob tam sim no tau qhia hauv daim duab txuas. Tom qab kho thiab lim, cov khoom siv hluav taws xob xa mus rau inverter Circuit Court kom ua rau inverter Circuit Court ua haujlwm thiab ua kom lub teeb pom kev nruab hnub nrig. Lub teeb hluav taws xob txuag hluav taws xob ntawm lub voj voog no muaj peev xwm ua rau daim phiaj nrog lub zog muaj zog txog 0.7. Raws li qhov tshwm sim ntawm lub tshuab lim dej, dc voltage input inverter Circuit, ripple coefficient siab dua, tab sis kuj ua rau muaj kuab paug rau lub zog hluav taws xob, cuam tshuam ntau dua rau cov khoom siv hauv tsev. Cov teeb meem saum toj no tuaj yeem daws tau zoo los ntawm kev ua cov kev txhim kho hauv qab no hauv Circuit Court.
1. Txo lub peev xwm lim lub zog, lub zog tuaj yeem nce mus rau ntau dua 0.85. Lub ripple coefficient tuaj yeem txo qis tau zoo los ntawm kev hloov cov lim lim mus rau lim lim. Txhawm rau ua qhov no, tshem C1 los ntawm daim duab txuas thiab hloov nws nrog ntu uas qhia los ntawm kab kab. Lub peev xwm ntawm C' 1 thiab C' 2 sib txawv nrog lub wattage ntawm lub teeb: 4.7μF/250V rau kev siv lub raj raj hauv qab 15W; 10μF/250V thaum siv teeb 15-30W, 22μF/250V thaum siv teeb 30W. D' 1 n4007.
2. Cov inductance coil L0 txuas nrog hauv kab lus ntawm qhov kawg ntawm AC 220V, thiab lub capacitor C0 tau koom ua ke, uas tuaj yeem tiv thaiv kev ua qias tuaj ntawm lub ballast mus rau lub zog hluav taws xob, thiab tuaj yeem txo qhov cuam tshuam tam sim no ntawm transistor BG1 thiab BG2 thaum lub zog hloov pauv, thiab txuas ntxiv txhim kho lub zog zoo.
3. Hloov thawj triode C2482 nrog C2258, thiab cov txiaj ntsig zoo.
4. Tom qab kev txhim kho saum toj no, qhov ci ntawm lub teeb yuav raug txo. Kev daws yog tshem tawm L2' tus tub ntxhais, npog nws nrog txheej ntawv thiab ntxig nws rov qab rau hauv, thiab saib qhov kev hloov pauv qhov ci. Rov ua ob peb zaug kom txog rau thaum qhov pom kev zoo. Thaum kawg, kaw cov hlau nplaum sib nqus nrog siv quav ciab.
