Qhov zoo thiab qhov tsis zoo ntawm Ib Nrab Choj Transformer Hloov Hom Fais Fab Khoom
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 transistors hloov pauv, nws yog qhov sib npaug rau ob lub zog hloov hluav taws xob ib txhij tso tawm hluav taws xob, uas 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 nthwv dej rectification, qhov voltage ripple coefficient Sv thiab tam sim no ripple coefficient Si ntawm cov zis voltage yog tsawg heev, thiab tsuas yog ib tug me me lim inductor thiab capacitor yuav tsum tau. Cov zis voltage ripple thiab tam sim no ripple tuaj yeem ua tiav me me.
Qhov zoo tshaj plaws ntawm ib nrab choj hloov hluav taws xob hloov hluav taws xob yog qhov yuav tsum tau muaj hluav taws xob rau ob lub tshuab hloov hluav taws xob tuaj yeem raug txo los ntawm ib nrab piv rau qhov yuav tsum tau muaj hluav taws xob rau ob qho khoom siv hloov pauv hauv lub laub-rub transformer switching fais fab mov. Vim tias qhov ua haujlwm voltage ntawm ob lub tshuab hloov pauv hauv 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, nws qhov siab tshaj plaws tiv thaiv hluav taws xob yog sib npaug ntawm qhov ua haujlwm voltage thiab lub zog hluav taws xob rov qab, uas yog kwv yees li ob zaug. lub zog hluav taws xob voltage. Qhov tshwm sim no yog raws nraim ib nrab ntawm qhov kev tiv thaiv hluav taws xob ntawm ob lub tshuab hloov pauv hauv lub laub-rub transformer hloov fais fab mov. Yog li ntawd, ib nrab choj transformer hloov cov khoom siv hluav taws xob feem ntau yog siv nyob rau hauv cov xwm txheej uas cov input voltage kuj siab. Feem ntau cov khoom siv hluav taws xob hloov hluav taws xob siv hluav taws xob siv los ntawm AC 220V nyob rau hauv daim phiaj siv hluav taws xob siv ib nrab choj hloov pauv hloov cov khoom siv hluav taws xob.
Thawj kauj ruam ntawm transformer nyob rau hauv ib nrab choj switching fais fab mov tsuas yog yuav tsum tau ib tug winding, uas kuj yog nws qhov zoo dua. Qhov no ua rau qee qhov yooj yim rau lub winding ntawm lub kauj hauv cov hluav taws xob qis hluav taws xob hloov hluav taws xob hloov pauv. Tab sis tsis muaj qhov zoo dua nyob rau hauv winding lub coils ntawm high-power switching fais fab transformers, vim hais tias cov coils ntawm high-power switching fais fab transformers yuav tsum tau raug mob nrog ntau yam strands ntawm hlau.
Lub ntsiab qhov tsis zoo ntawm ib nrab choj transformer hloov hluav taws xob yog qhov kev siv hluav taws xob tsawg tsawg. Yog li ntawd, ib nrab choj transformer hloov fais fab mov tsis haum rau cov ntawv thov uas tsis tshua muaj kev khiav hauj lwm voltage. Tsis tas li ntawd, ob qho khoom siv hloov pauv hauv ib nrab choj hloov pauv hloov hluav taws xob tsis txuas nrog hauv av, uas ua rau nws nyuaj rau kev txuas nrog lub teeb liab tsav tsheb.
Qhov loj tshaj qhov tsis zoo ntawm ib nrab choj hloov hluav taws xob yog tias thaum ob lub chaw tswj kev hloov pauv K1 thiab K2 nyob rau hauv kev hloov pauv hloov pauv, ob qho tib si hloov pauv yuav ib txhij muaj lub sijhawm luv luv ntawm thaj chaw ib puag ncig, uas yog, ob qho tib si tswj kev hloov pauv yuav nyob hauv. nyob rau 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 transitional txheej txheem los ntawm lub off-lub xeev mus rau lub tag nrho cov coj lub xeev; Thaum lub tshuab hluav taws xob hloov pauv hloov ntawm lub xeev coj mus rau lub xeev txiav tawm, nws yog qhov sib npaug rau kev tso tawm lub capacitor, thiab nws tseem yuav tsum tau muaj cov txheej txheem hloov pauv los ntawm lub xeev ua haujlwm mus rau lub xeev txiav tawm tag nrho.
Thaum ob lub tshuab hloov pauv nyob rau hauv cov txheej txheem kev hloov pauv ntawm kev coj ua thiab kev txiav tawm feem, uas yog, thaum ob qho tib si hloov khoom siv nyob rau hauv lub xeev semi conductive, nws yog sib npaug rau ob lub tshuab hluav taws xob tswj tau qhib tib lub sijhawm, uas yuav ua rau luv luv Circuit Court. mus rau lub hwj chim mov voltage; Nyob rau ntawm lub sijhawm no, qhov tam sim no loj yuav tshwm sim nyob rau 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 pauv thaum ob qho tib si tswj kev hloov pauv K1 thiab K2 nyob rau hauv tib lub xeev, ob lub tshuab hloov pauv yuav ua rau lub zog loj 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 hloov lub sijhawm rau thiab tawm ntawm ob lub tshuab hluav taws xob tswj los ntawm lub sijhawm me me hauv ib nrab choj hloov hluav taws xob hloov hluav taws xob.
Ib qho capacitor ib nrab choj transformer hloov fais fab mov txuag ib lub capacitor piv rau ob lub capacitor ib nrab choj transformer hloov fais fab mov, uas yog nws qhov zoo dua. Tsis tas li ntawd, thaum tib lub capacitor ib nrab choj transformer hloov lub hwj chim mov thawj zaug pib ua hauj lwm, cov zis voltage yuav luag ob zaug siab npaum li ntawm ob lub capacitor ib nrab choj transformer switching fais fab mov. Cov yam ntxwv no yog qhov tsim nyog tshaj plaws raws li lub teeb hluav taws xob fluorescent, xws li lub zog txuag hluav taws xob lossis cov teeb fluorescent, nrog rau cov teeb pom kev zoo rau cov ntxaij vab tshaus LCD.
Fluorescent teeb feem ntau xav tau qhov hluav taws xob siab thaum pib teeb pom kev zoo, xws li los ntawm ntau pua volts mus rau ntau txhiab volts, thaum lub zog ua haujlwm tom qab teeb pom kev tsuas xav tau kaum tawm volts rau ntau tshaj li ib puas volts. Yog li ntawd, yuav luag txhua lub teeb txuag hluav taws xob siv tib lub capacitor ib nrab choj transformer hloov cov khoom siv hluav taws xob.
