Qhov sib txawv ntawm hloov hom fais fab mov thiab transformer
Ua ntej ntawm tag nrho cov, lub switching fais fab mov yog DC - DC, lub transformer yog AC - AC; Qhov thib ob, lub zog hloov hluav taws xob ua haujlwm ntawm ntau zaus (feem ntau nyob rau hauv kaum ob ntawm kilohertz), thaum lub tshuab hloov hluav taws xob muaj ntau zaus, kuj tseem muaj qhov tsawg zaus, hloov hluav taws xob siv hauv lub pulse transformer yog lub tshuab hluav taws xob siab. , cov tub ntxhais hlau yog ib qho ferrite xws li cov tub ntxhais, qhov ntim me me, kev ua haujlwm siab (qhov siab dua qhov zaus ntawm qhov kev ua haujlwm siab yuav siab dua), hais tias transformer peb thawj zaug xav txog qhov yog qhov muaj zaus transformer, nws cov kev khiav hauj lwm. zaus ntawm 50 hertz, belongs rau low-frequency transformer, cov tub ntxhais yuav tsum tau stacked nrog mos magnetic khoom silicon steel ntawv (kom tiv thaiv eddy tam sim no tsim joule tshav kub); dua: ob pawg ua haujlwm tsis zoo ib yam, hloov hom hluav taws xob muaj lub tshuab hloov pauv, tab sis kuj muaj ib feem ntawm cov khoom siv hluav taws xob ntawm sab sauv thiab qis kawg, tsis hais qhov zaus ntawm qhov hloov pauv yog qhov hloov hluav taws xob, tsis muaj rectifier muaj nuj nqi;
Yog hais tias peb tham txog cov teeb meem, cia peb tham txog lub hwj chim mov Circuit Court ntawm lub TV teeb! Lub hwj chim mov ib feem ntawm cov xim TV yog ib tug raug switching fais fab mov; yav dhau los, lub hwj chim mov Circuit Court ib feem ntawm lub dub-thiab-dawb TV teeb yog lub industrial zaus transformer ntxiv rau lub rectifier, lim thiab voltage regulator Circuit Court muaj pes tsawg leeg. Xim TV fais fab mov yog 220V AC lub zog ncaj qha mus rau 300V DC, thiab tom qab ntawd txiav los ntawm kev hloov pauv hloov mus rau hauv cov mem tes siab, thiab tom qab ntawd los ntawm cov pulse core transformer step-down, thiab tom qab ntawd kho cov lim tso tawm qis-voltage DC (nws yog tag nrho cov txheej txheem ntawm kev tswj qhov teeb meem ntawm kev daws teeb meem); cov sum ntawm cov txheej txheem no yog hais tias pheej yig switching fais fab mov. Cov dub thiab dawb TV teeb nyob rau hauv industrial zaus transformer qub tij laug ib tug neeg sawv cev ntawm lub transformer koj hais, nws tsis muaj rectifier lim circuit. Yog li ob qho tib si tsis muaj qhov ua haujlwm zoo ib yam.
