Ib nrab choj transformer hloov fais fab mov cov txiaj ntsig thiab qhov tsis zoo
Ib nrab choj transformer switching fais fab mov yog zoo ib yam li lub laub-rub transformer switching fais fab mov. Vim yog kev hloov pauv ntawm ob lub raj hloov pauv, nws yog sib npaug rau ob lub zog hloov hluav taws xob tso tawm lub zog ib txhij, thiab nws lub zog tso tawm yog kwv yees li ob npaug ntawm cov zis hluav taws xob ntawm ib qho kev hloov hluav taws xob. Yog li ntawd, ib nrab choj transformer hloov fais fab mov muaj lub zog tso zis ntau thiab ua haujlwm siab. Tom qab choj rectification los yog tag nrho yoj rectification, qhov voltage ripple coefficient Sv thiab tam sim no ripple coefficient Si ntawm cov zis voltage yog ob qho tib si tsawg heev. Nrog tsuas yog ib qho me me lim inductance thiab capacitor, cov zis voltage ripple thiab tam sim no ripple tuaj yeem me me heev.
Qhov zoo tshaj plaws ntawm ib nrab choj transformer hloov hluav taws xob yog qhov uas yuav tsum tau muaj hluav taws xob tiv thaiv rau ob lub tshuab hloov pauv tuaj yeem raug txo los ntawm ib nrab piv rau lub laub-rub transformer hloov fais fab mov. Vim tias qhov ua haujlwm voltage ntawm ob lub tshuab hloov pauv ntawm ib nrab choj hloov hluav taws xob hloov hluav taws xob tsuas yog ib nrab ntawm cov khoom siv hluav taws xob hluav taws xob Ui, thiab nws qhov siab tshaj plaws tiv thaiv hluav taws xob yog sib npaug ntawm qhov ua haujlwm voltage thiab rov qab electromotive quab yuam, uas yog hais txog. ob zaug ntawm lub hwj chim mov voltage. Qhov tshwm sim no yog raws nraim ib nrab ntawm qhov kev tiv thaiv hluav taws xob ntawm ob lub cuab yeej hloov pauv ntawm lub laub-rub transformer hloov hluav taws xob. Yog li ntawd, ib nrab choj transformer switching fais fab mov yog tsuas yog siv nyob rau hauv cov xwm txheej nrog high input voltage. Feem ntau, cov khoom siv hluav taws xob siab hloov hluav taws xob nrog daim phiaj hluav taws xob ntawm AC 220V feem ntau yog siv los ntawm ib nrab choj transformer hloov cov khoom siv hluav taws xob.
Lub transformer thawj kauj ntawm ib nrab choj hloov hluav taws xob tsuas yog xav tau ib qho winding, uas yog nws qhov zoo dua. Qhov no coj qee qhov yooj yim rau lub winding ntawm lub kauj ntawm lub zog qis hluav taws xob hloov hluav taws xob hloov hluav taws xob. Txawm li cas los xij, tsis muaj qhov ua tau zoo ntawm winding lub coils ntawm high-power switching fais fab transformers, raws li cov coils ntawm high-power switching fais fab transformers yuav tsum tau ntau strands ntawm hlau yuav raug mob.
Lub ntsiab drawback ntawm ib nrab choj transformer switching fais fab mov yog nws tsawg zog siv tus nqi. Yog li ntawd, ib nrab choj transformer hloov fais fab mov tsis haum rau cov ntawv thov uas tsis tshua muaj hluav taws xob ua haujlwm. Tsis tas li ntawd, kev sib txuas ntawm ob qho khoom siv hloov pauv hauv ib nrab choj hloov pauv hloov hluav taws xob tsis muaj qhov sib xws, uas yog qhov teeb meem ntau dua rau kev txuas rau lub teeb liab tsav tsheb.
Qhov teeb meem loj tshaj plaws ntawm ib nrab choj hloov hluav taws xob yog tias thaum ob lub tshuab hluav taws xob tswj K1 thiab K2 nyob rau hauv kev hloov pauv hloov, ob qho tib si hloov khoom siv yuav ua rau tib lub sijhawm luv luv ntawm thaj chaw ib puag ncig, uas yog, ob qho tib si tswj kev hloov pauv nyob rau hauv lub xeev. tib lub sijhawm. Qhov no yog vim hais tias thaum lub switching ntaus ntawv pib ua, nws yog sib npaug rau them lub capacitor, thiab nws yuav tsum tau ib tug kev hloov ntawm lub xeev txiav mus rau lub tag nrho coj lub xeev; Thaum lub tshuab hloov pauv hloov ntawm lub xeev mus rau lub xeev tawm, nws yog qhov sib npaug rau kev tso tawm lub capacitor, thiab nws tseem yuav tsum tau muaj kev hloov pauv ntawm lub xeev mus rau lub xeev tag nrho.
Thaum ob qho khoom siv hloov pauv raws li txoj kev hloov pauv ntawm kev coj ua thiab kev txiav tawm, uas yog, thaum ob qho tib si hloov khoom siv nyob rau hauv lub xeev semi conduction thiab semi conduction xeev, nws yog sib npaug rau ob lub tshuab hluav taws xob tswj tau qhib ib txhij, uas yuav ua rau luv luv. Circuit Court rau lub hwj chim mov voltage; Nyob rau ntawm lub sijhawm no, qhov loj ntawm tam sim no yuav tshwm sim hauv cov kab hluav taws xob ntawm ob lub tshuab hluav taws xob tswj, thiab qhov tam sim no tsis dhau los ntawm cov khoom siv hluav taws xob. Yog li ntawd, thaum lub sij hawm hloov ntawm ob qho tib si tswj keyboards K1 thiab K2, ob lub switching pab kiag li lawm yuav tsim ib tug tseem ceeb zog poob. Txhawm rau txo qhov poob los ntawm cov txheej txheem kev hloov pauv ntawm kev tswj cov keyboards, nws yog feem ntau txhob txwm ua rau stagger lub sijhawm rau thiab tawm ntawm ob lub tshuab hluav taws xob tswj rau lub sijhawm luv luv hauv ib nrab choj hloov hluav taws xob hluav taws xob.
Qhov kom zoo dua ntawm ib tug capacitor ib nrab choj transformer switching fais fab mov yog tias nws txuag tau ib tug capacitor piv rau ob lub capacitor ib nrab choj transformer switching fais fab mov. Tsis tas li ntawd, thaum tib lub capacitor ib nrab choj transformer hloov hluav taws xob ua ntej pib ua haujlwm, cov zis hluav taws xob yuav luag ob npaug ntawm ob lub capacitor ib nrab choj hloov hluav taws xob hloov hluav taws xob. Cov yam ntxwv no yog qhov tsim nyog tshaj plaws rau kev siv lub teeb hluav taws xob fluorescent, xws li lub teeb txuag hluav taws xob lossis cov teeb fluorescent, nrog rau cov teeb pom kev zoo rau cov ntxaij vab tshaus LCD.
Lub teeb fluorescent feem ntau xav tau qhov hluav taws xob siab thaum lawv pib teeb, txij li ob peb puas mus rau ob peb txhiab volts. Txawm li cas los xij, tom qab teeb pom kev zoo, qhov ua haujlwm voltage tsuas yog yuav tsum yog ob peb kaum mus rau ntau tshaj ib puas volts. Yog li ntawd, yuav luag txhua lub teeb txuag hluav taws xob siv tib lub capacitor ib nrab choj transformer hloov hluav taws xob.
