Qhov zoo thiab qhov tsis zoo ntawm ib nrab choj transformer hloov fais fab mov
Ib nrab-choj transformer switching fais fab mov yog tib yam li lub laub-rub transformer switching fais fab mov. Txij li thaum ob lub raj hloov pauv ua haujlwm sib hloov, nws yog qhov sib npaug ntawm cov khoom siv hluav taws xob ntawm ob lub zog hloov hluav taws xob tib lub sijhawm, thiab nws cov hluav taws xob tso tawm yog kwv yees li ob npaug ntawm ib qho kev hloov hluav taws xob. Yog li ntawd, ib nrab-bridge transformer switching fais fab mov muaj ib tug loj tso zis hwj chim thiab siab ua hauj lwm efficiency. Tom qab choj rectification los yog tag nrho-yoj rectification, voltage ripple coefficient Sv thiab tam sim no ripple coefficient Si ntawm cov zis voltage tsawg heev, thiab tsuas yog ib tug me me lim yuav tsum tau. Inductors thiab capacitors, cov zis voltage ripple thiab tam sim no ripple tuaj yeem me me heev.
Qhov zoo tshaj plaws ntawm ib nrab-choj transformer switching fais fab mov yog tias qhov kev tiv thaiv hluav taws xob rau ob lub tshuab hloov pauv tuaj yeem raug txo los ntawm ib nrab piv nrog lub laub-rub transformer hloov hluav taws xob rau ob qho khoom siv hloov. Vim tias qhov ua haujlwm voltage ntawm ob lub tshuab hloov hluav taws xob ntawm ib nrab-bridge transformer hloov hluav taws xob tsuas yog ib nrab ntawm cov khoom siv hluav taws xob Ui, 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 lub laub-rub hom Transformer switching fais fab mov yog ib nrab ntawm kev tiv thaiv hluav taws xob ntawm ob lub tshuab hloov pauv. Yog li ntawd, ib nrab-bridge transformer switching fais fab mov yog tsuas yog siv nyob rau hauv lub sij hawm uas lub input voltage yog kuj siab. Feem ntau, feem ntau cov hluav taws xob hloov hluav taws xob hloov hluav taws xob nrog cov kab hluav taws xob ntawm 220 volts ntawm AC fais fab mov siv ib nrab choj hloov hluav taws xob hloov hluav taws xob.
Lub transformer thawj kauj ntawm ib nrab-choj hloov fais fab mov tsuas yog xav tau ib qho winding, uas yog nws qhov zoo dua, uas ua rau qee qhov yooj yim rau coil winding ntawm me me hluav taws xob hloov hluav taws xob transformer. Txawm li cas los xij, tsis muaj qhov zoo dua rau coil winding ntawm high-power switching power supply transformers, vim hais tias cov coils ntawm high-power switching fais fab mov transformers yuav tsum raug mob nrog ntau txoj hlua hlau.
Lub ntsiab tsis zoo ntawm ib nrab-bridge transformer switching fais fab mov yog tias lub hwj chim siv tus nqi kuj tsawg. Yog li ntawd, ib nrab-bridge transformer switching fais fab mov tsis haum rau lub sij hawm uas tsis tshua muaj ua hauj lwm voltage. Tsis tas li ntawd, ob qho khoom siv hloov pauv hauv ib nrab-bridge transformer hloov hluav taws xob tsis txuas nrog hauv av, yog li nws muaj teeb meem 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 tshuab hluav taws xob tswj K1 thiab K2 nyob rau hauv kev hloov pauv hloov, ob lub tshuab hloov pauv yuav tshwm sim nyob rau hauv ib cheeb tsam luv luv, uas yog, ob. tswj keyboards nyob rau hauv tib lub xeev nyob rau tib lub sij hawm. txuas lub xeev. Qhov no yog vim hais tias thaum lub switching ntaus ntawv pib ua, nws yog sib npaug rau them lub capacitor, thiab nws xav tau ib tug kev hloov ntawm lub xeev mus rau lub tag nrho ntawm lub xeev; thiab thaum lub tshuab hluav taws xob hloov pauv los ntawm lub xeev mus rau lub xeev tawm, nws yog qhov sib npaug rau kev them nyiaj rau lub capacitor Discharge, nws kuj xav tau txoj kev hloov pauv ntawm lub xeev conduction mus rau lub xeev txiav tawm tiav.
Thaum ob lub tshuab hloov pauv nyob rau hauv qhov kev hloov pauv thiab kev hloov pauv raws li txoj cai, uas yog, thaum ob lub tshuab hloov pauv nyob rau hauv lub xeev ib nrab, thaum ob lub tshuab hloov pauv nyob rau hauv lub xeev ib nrab, nws yog sib npaug. ob lub tshuab hluav taws xob tswj tau qhib tib lub sijhawm. luv luv; Nyob rau lub sijhawm no, cov tam sim no loj 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 txoj kev hloov ntawm ob lub tswj keyboards K1 thiab K2 nyob rau tib lub sij hawm, ob lub switching li yuav ua rau ib tug loj lub zog poob. Txhawm rau txo qhov poob los ntawm cov txheej txheem kev hloov pauv ntawm kev tswj kev hloov, feem ntau nyob rau hauv ib nrab-bridge hloov hluav taws xob hloov hluav taws xob, lub sijhawm tig thiab tig tawm ntawm ob lub tshuab hluav taws xob tswj tau txhob txwm staggered rau lub sijhawm luv luv. .
Ib qho-capacitor ib nrab-choj transformer hloov fais fab mov txuag ib lub capacitor dua li ob-capacitor ib nrab-txoj kev hloov hluav taws xob hloov hluav taws xob, uas yog nws qhov zoo dua. Tsis tas li ntawd, thaum ib leeg-capacitor ib nrab-txoj kev hloov pauv hloov hluav taws xob pib ua haujlwm, qhov tso zis hluav taws xob yuav luag ob zaug siab dua li ntawm ob-kab hluav taws xob ib nrab-choj transformer hloov hluav taws xob. Cov yam ntxwv no yog qhov tsim nyog tshaj plaws raws li lub teeb hluav taws xob fluorescent, piv txwv li, lub teeb txuag hluav taws xob lossis fluorescent teeb thiab backlights rau LCD zaub, thiab lwm yam.
Lub teeb fluorescent feem ntau xav tau qhov hluav taws xob siab thaum lawv pib teeb, txog li ob peb puas volts mus rau ob peb txhiab volts, thiab tom qab lawv tau teeb, qhov ua haujlwm voltage xav tau kaum tawm volts rau ntau tshaj 100 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.
Ib leeg-capacitor ib nrab-txoj kev hloov hluav taws xob hloov hluav taws xob kuj tseem muaj qhov tsis zoo, uas yog, qhov yuav tsum tau muaj qhov ntsuas hluav taws xob ntawm kev hloov khoom siv yog siab dua li ntawm ob-kab hluav taws xob ib nrab-choj transformer hloov hluav taws xob.
