Qhov zoo ntawm kev hloov cov khoom siv hluav taws xob tswj tau:
Hloov fais fab mov circuits tuaj yeem faib ua ob hom: series thiab parallel. Nws yog ncaj qha rectified kom tau txais high-voltage DC, thiab cov zis voltage yog kho los ntawm kev tswj lub sij hawm piv ntawm lub on-off ntawm lub switching hlab los ntawm ib tug high-frequency oscillator.
Advantage 1: Cov ntsiab lus yooj yim: kev siv hluav taws xob tsawg, kev ua haujlwm siab, me me thiab hnav
Nws qhov txiaj ntsig loj tshaj plaws yog qhov ua tau zoo yuav tsum siab dua. Yog vim li cas yog tias nyob rau hauv lub xeev hloov, lub transistor nws tus kheej siv tsawg functionality, nws tus kheej muaj peev xwm ncav cuag 70% los yog 80% ntawm cov efficiency, nyob rau tib lub sij hawm tsis xav tau ib kauj ruam-down transformer, nws cov zis transformer ua hauj lwm ntawm high zaus, thiab Lub ntim yog tsawg dua 50 Hz industrial zaus transformer. Yog li qhov hloov hluav taws xob tswj hluav taws xob muaj qhov zoo ntawm qhov me me thiab lub teeb yuag. Nws tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov loj voltage ntau.
Advantage 2: dav voltage ntau
Cov zis hluav taws xob los ntawm kev hloov hluav taws xob tswj hluav taws xob yog tswj hwm los ntawm lub luag haujlwm lub voj voog ntawm lub teeb liab excitation, thiab kev hloov pauv ntawm cov teeb liab input voltage tuaj yeem raug them los ntawm kev hloov kho zaus los yog nthuav dav, yog li ntawd nyob rau hauv cov ntaub ntawv ntawm kev hloov loj nyob rau hauv daim phiaj muaj zaus. voltage, nws tseem tuaj yeem ua kom ruaj khov qhov tso zis voltage. Raws li kev hais lus, qhov voltage stabilization ntau ntawm kev hloov fais fab mov yog qhov dav heev, thiab cov nyhuv voltage stabilization yog qhov zoo.
Qhov zoo 3: daim ntawv hloov pauv hloov pauv
Piv txwv li, muaj kev txaus siab rau tus kheej thiab lwm yam excitation hom, muaj kev nthuav dav thiab ntau zaus kev tswj hwm hom, ib leeg-kawg thiab ob-kawg, thiab lwm yam, cov neeg tsim khoom siv hluav taws xob tuaj yeem ua si qhov zoo ntawm ntau hom circuits, tsim thiab kev loj hlob kom tau raws li cov kev siv sib txawv ntawm switching tswj fais fab mov.
Disadvantages ntawm switching tswj fais fab mov
Disadvantage 1: Hloov cuam tshuam
Kev cuam tshuam loj ntawm kev hloov pauv yog qhov tsis zoo tshaj plaws ntawm kev hloov hluav taws xob tswj hluav taws xob. Kev hloov hluav taws xob tswj hluav taws xob, hloov hluav taws xob hloov pauv transistor V ua haujlwm nyob rau hauv lub xeev hloov, nws tsim AC voltage thiab tam sim no los ntawm lwm cov khoom hauv Circuit Court los tsim kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam resonance, cov kev cuam tshuam no yog tias koj tsis siv qee yam kev tiv thaiv, tshem tawm thiab shielding, yuav cuam tshuam rau kev ua haujlwm ntawm lub tshuab.
Disadvantage 2: Complex circuit structure, siab tsis ua hauj lwm tus nqi, txij nkawm teeb meem. Kev tu thiab tus nqi siab ntawm kev tsim kho
Hauv daim ntawv no, peb txheeb xyuas cov khoom siv hluav taws xob tswj hwm, uas tuaj yeem muab faib ua cov khoom siv hluav taws xob zoo tib yam thiab hloov hom tswj fais fab mov. Nyob rau tib lub sijhawm piav qhia txog qhov zoo thiab qhov tsis zoo ntawm kev hloov pauv-hom tswj fais fab mov, kev nkag siab txog cov teeb meem no kom ntxaws hauv tus txheej txheem ntawm kev tsim thiab tsim cov khoom siv hluav taws xob hloov pauv yuav yog ib qho kev pab.
