Lub tswv yim tseem ceeb ntawm kev hloov hluav taws xob
Nrog rau txoj kev loj hlob sai ntawm lub zog hluav taws xob thev naus laus zis, kev sib raug zoo ntawm cov khoom siv hluav taws xob hluav taws xob thiab tib neeg txoj haujlwm thiab lub neej tau dhau los ua ze, thiab cov khoom siv hluav taws xob yog sib cais los ntawm cov khoom siv hluav taws xob uas ntseeg tau. Nyob rau xyoo 1980, lub khoos phis tawj hluav taws xob tau paub txog qhov hloov pauv hluav taws xob, thiab ua tus thawj coj ua kom tiav lub khoos phis tawj. Nyob rau xyoo 1990, hloov cov khoom siv hluav taws xob nkag mus rau ntau yam khoom siv hluav taws xob thiab hluav taws xob ib qho tom qab. Kev tswj cov keyboards, kev sib txuas lus, cov khoom siv hluav taws xob ntsuas hluav taws xob, cov khoom siv hluav taws xob tswj cov khoom siv hluav taws xob, thiab lwm yam tau siv dav siv cov khoom siv hluav taws xob hloov hluav taws xob, uas tau txhawb txoj kev loj hlob sai ntawm kev siv hluav taws xob hloov hluav taws xob. . Hloov fais fab mov yog ib hom khoom siv hluav taws xob uas siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob los tswj lub sij hawm piv ntawm kev hloov transistor rau thiab tawm kom tswj tau qhov tso zis hluav taws xob ruaj khov. Kev hloov hluav taws xob feem ntau yog tsim los ntawm pulse width modulation (PWM) tswj IC thiab MOSFET. Piv nrog rau cov khoom siv hluav taws xob linear, tus nqi ntawm cov khoom siv hluav taws xob hloov hluav taws xob nce ntxiv nrog qhov nce ntawm cov zis hluav taws xob, tab sis qhov kev loj hlob ntawm ob qhov sib txawv. Ntawm ib qho chaw tso zis hluav taws xob, tus nqi ntawm cov khoom siv hluav taws xob tawm yog siab dua li ntawm kev hloov hluav taws xob, uas yog tus nqi thim rov qab. Nrog rau kev txhim kho thiab kev tsim kho tshiab ntawm lub zog hluav taws xob thev naus laus zis, kev hloov hluav taws xob thev naus laus zis tau hloov kho tas li, thiab qhov kev hloov pauv ntawm tus nqi no tau nce mus rau qhov qis tso zis hluav taws xob, uas muab qhov chaw dav dav rau kev hloov hluav taws xob. Lub siab zaus ntawm kev hloov fais fab mov yog cov kev taw qhia ntawm nws txoj kev loj hlob. High zaus ua rau switching fais fab mov miniaturized, thiab ua rau switching fais fab mov nkag mus rau ib tug dav daim ntawv thov teb, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov ntawm high-tech teb, uas txhawb lub miniaturization thiab portability ntawm high-tech khoom hloov. Tsis tas li ntawd, kev txhim kho thiab kev siv cov khoom siv hluav taws xob hloov pauv yog qhov tseem ceeb hauv kev txuag hluav taws xob, txuag cov peev txheej thiab tiv thaiv ib puag ncig.
Lub tshuab hluav taws xob hloov hluav taws xob yog siv lub tshuab hluav taws xob los tswj lub raj xa hluav taws xob kom ua haujlwm siab ceev rau thiab tawm. Cov tam sim no ncaj qha hloov mus rau hauv high-frequency alternating tam sim no thiab nkag mus rau lub transformer rau voltage transformation, yog li tsim ib los yog ntau tshaj ntawm voltages yuav tsum tau! Yog vim li cas rau kev hloov mus rau Huawei lub high-frequency AC yog tias cov efficiency ntawm high-frequency AC nyob rau hauv lub transformer transformation Circuit Court yog ntau dua li ntawm 50HZ. Yog li qhov hloov pauv hloov pauv tuaj yeem ua rau me me, thiab nws tsis kub heev thaum ua haujlwm! Tus nqi qis heev. Yog tias koj tsis hloov 50HZ mus rau qhov siab, ces kev hloov hluav taws xob tsis muaj nuj nqis! ! Hloov cov transformers tsis yog qhov txawv txav. Tsuas yog ib qho yooj yim transformer! Qhov no yog switching power supply. Hloov cov khoom siv hluav taws xob tuaj yeem faib ua ob hom: cais thiab tsis cais. Hom kev rho tawm yuav tsum muaj qhov hloov pauv hloov pauv, tab sis qhov tsis cais tawm yuav tsis tas muaj nws.
Thaum lub hwj chim zoo ib yam, qhov siab dua qhov hloov zaus, qhov me me ntawm qhov hloov pauv hloov pauv, tab sis qhov siab dua qhov yuav tsum tau ua rau lub raj hloov pauv; qhov thib ob ntawm kev hloov pauv hloov pauv tuaj yeem muaj ntau yam windings lossis ib qho winding muaj ntau yam kais dej kom tau txais cov zis tso zis; Feem ntau, qee qhov kev tiv thaiv Circuit Court yuav tsum tau ntxiv, xws li tsis muaj-load, luv-circuit thiab lwm yam kev tiv thaiv, txwv tsis pub lub switching fais fab mov yuav raug hlawv.
