Switching Hwj chim Mov - ib tug txhim khu kev qha nrog rau hluav taws xob

Yuav luag txhua hluav taws xob khoom yuav tsum siv cov khoom siv fais fab. Lub fact tias cov mov voltage yog heev feem ntau tsis yog tib yam li dab tsi yog yuav tsum tau rau cov pab kiag li lawm, qhov ntau lawv yuav tsum tau xyuas kom meej lub txuas ntxiv thiab uninterrupted fais fab mov. Muaj tsawg tsawg heev los yog high voltage jumps sai sai tso zis rau lub network los ntawm tej khoom siv ua hauj lwm. Cov tshuaj rau qhov teeb meem no twb pom nyob rau hauv ib tug ntev lub sij hawm - yog siv lub hwj chim mov uas regulates voltage thiab tiv thaiv tus ntaus ntawv.

Niaj hnub no cov kev siv ntawm ib tug linear thiab ib tug switching fais fab mov. Ua ntej kuv tau txais kis vim hais tias ntawm lawv cov simplicity, ceev cov lus teb rau tej load hloov thiab stability. Tab sis muaj drawbacks: tsawg efficiency, bulkiness ntawm lub transformer, qhov rhiab heev rau lub tswv yim voltage thiab kub dissipation. Vim li no, linear khoom siv fais fab maj mam hloov los ntawm mem tes, uas muaj ib tug comparatively kev kawm zoo.

Nyob rau hauv peb lub sij hawm, muaj cov miniaturization ntawm lub apparatus, li ntawd, transformer fais fab mov Circuit Court yuav twb yuav outdated. Switching fais fab mov muaj ib tug lossis loj tus naj npawb ntawm zoo, cov uas sawv tawm lub winding khoom nyiaj, thiab qhov no yuav txo tau nyob rau hauv tus nqi ntawm cov ntaus ntawv nws tus kheej, zoo huv si qhov ntev, cia siab rau, ntau kev khiav hauj lwm ntau yam. Cov qualities yuav tsis tau overlooked los ntawm xov tooj cua amateurs thiab cov tub txawg. Txawm li cas los, muaj ib tug drawback: txawm tias ib tug yooj yim hloov hom fais fab mov muaj ib tug elaborate tswvyim kom dhos thiab teem, tab sis qhov no fact tsis nres lub tiag tiag masters.

Ib ce txawm tias ntau kim tshaj cov pa blocks, tab sis lawv tsis tsuas tau thiab ib tug transmitter mov voltage, tab sis nws yog stabilized los ntawm tiv thaiv nws tus kheej thiab ntau yam theem ntawm cov teeb meem. Nws yog tam sim no dav siv switching fais fab mov rau ib tug suab zaus amplifier, microcontroller-raws li pab kiag li lawm, thiab automation txhais tau tias rau lwm yam ntau yam apparatus. Chiv, lawv tau siv nyob rau hauv TV poob lawm thiab ntau yam video khoom.

Switching fais fab mov twb tsim nws tus kheej li ib tug yig, txhim khu kev qha thiab yooj yim rau siv ntaus ntawv. Tam sim no manufacturers yog koom nyob rau hauv ib tug kev hloov kho ntawm cov uas twb ua qauv nyob rau hauv cov nqe lus ntawm miniaturization ntawm lub caij puag, thiab txhim kho cov kev ntseeg ntawm tus dais.

Muaj ntau ntau ce schemes, tab sis lawv ua hauj lwm yuav luag nyob rau hauv tib lub ntsiab cai. Tib txhaj koob tshuaj tivthaiv generator txau twb rectified mains voltage, ib tug mem tes transformer nrog ob load yog ib tug rectifier, thiab los yeej muaj yog pub los ntawm cov neeg. Nyob ntawm seb tus qauv, lub generator tej zaum yuav sab nraud los yog ib tug self-starting. transistor generator ua hauj lwm nyob rau hauv lub switching hom. Thaum nws yog kaw, tag nrho cov zog mus rau hauv lub load, thiab thaum qhib - nyob rau hauv mem tes transformer muab lub zog.

Switching fais fab mov stabilizes thiab converts hluav taws xob lub zog los ntawm AC network rau lub zog yuav tsum tau mus faiv fab tso lub ntau yam khoom. Kev khiav hauj lwm voltage AC, uas yog tsis haum rau ntau pab kiag li lawm thiab txo lawv cov kev siv ntawm lub sij hawm. Lub hwj chim muab chav tsev tiv thaiv cov khoom, dua xwb tau voltage tsis mus tshaj cov kev txwv.
