Qhov zoo thiab qhov tsis zoo ntawm kev hloov hluav taws xob thiab cov khoom siv hluav taws xob linear
Qhov zoo thiab qhov tsis zoo ntawm kev hloov fais fab mov
Cov txiaj ntsig tseem ceeb: me me, lub teeb yuag (qhov ntim thiab qhov hnyav tsuas yog 20-30 feem pua ntawm cov khoom siv hluav taws xob), kev ua haujlwm siab (feem ntau 60-70 feem pua, thaum lub zog linear tsuas yog {{2} } feem pua), muaj zog tiv thaiv kev cuam tshuam muaj peev xwm, tso zis voltage Dav dav, modular.
Qhov tsis zoo tseem ceeb: vim yog qhov hluav taws xob ntau zaus tsim nyob rau hauv inverter Circuit Court, muaj qee yam cuam tshuam rau cov khoom siv nyob ib puag ncig. Yuav tsum muaj kev tiv thaiv zoo thiab grounding. Hloov tam sim no yog kho kom tau txais cov tam sim no ncaj qha. Txawm li cas los xij, vim muaj kev hloov pauv hauv AC voltage thiab load tam sim no, DC voltage tau txais tom qab kho feem ntau ua rau muaj qhov hloov pauv ntawm 20% mus rau 40 feem pua. Txhawm rau kom tau txais qhov ruaj khov DC voltage, yuav tsum siv qhov hluav taws xob stabilizing Circuit Court kom ua tiav qhov hluav taws xob stabilization.
Pros thiab Cons ntawm Linear Power Supplies
Qhov zoo: Qhov zoo ntawm linear fais fab mov yog cov qauv yooj yim, cov zis me me ripple, thiab tsis tshua muaj kev cuam tshuam. Qhov txiaj ntsig loj tshaj plaws uas cov qauv yooj yim coj peb yog qhov yooj yim ntawm kev saib xyuas. Qhov nyuaj ntawm kev tswj xyuas cov khoom siv hluav taws xob linear feem ntau qis dua li ntawm kev hloov hluav taws xob, thiab kev saib xyuas kev ua tiav ntawm cov khoom siv hluav taws xob linear kuj ntau dua li ntawm kev hloov hluav taws xob. Ripple yog AC tivthaiv superimposed ntawm DC stabilizer. Qhov me me ntawm cov zis ripple txhais tau hais tias qhov siab dua qhov purity ntawm cov zis DC lub zog, uas kuj yog ib qho tseem ceeb ntawm lub cim ntawm qhov zoo ntawm DC fais fab mov. Qhov ncaj qha tam sim no nrog cov ripple siab dhau lawm yuav cuam tshuam rau kev ua haujlwm ntawm lub transceiver. Tam sim no, ripple ntawm qib high-qib linear fais fab mov tuaj yeem ncav cuag qib ntawm 0.5mV, thiab cov khoom siv dav dav tuaj yeem ncav cuag 5mV. Cov khoom siv hluav taws xob linear tsis muaj cov khoom siv uas ua haujlwm ntawm cov khoom siv ntau zaus, yog li yuav luag tsis muaj kev cuam tshuam ntau zaus / lub suab nrov yog tias cov khoom siv lim tau ua tiav zoo.
Disadvantages: Yuav tsum muaj ib tug loj thiab hnyav transformer, thiab qhov luaj li cas thiab qhov hnyav ntawm lub lim capacitor yuav tsum tau loj heev, thiab lub voltage tawm tswv yim Circuit Court ua hauj lwm nyob rau hauv ib tug linear lub xeev, thiab muaj ib tug tej yam voltage poob ntawm lub adjustable raj, uas ua rau ib tug ntau yam ntawm kev hloov. loj kev khiav hauj lwm tam sim no thaum outputting loj ua hauj lwm tam sim no. Lub hwj chim noj ntawm lub raj hloov yog loj heev, qhov kev hloov dua siab tshiab yog qhov tsawg, thiab lub dab dej kub loj yuav tsum tau nruab. Hom fais fab mov no tsis haum rau cov kev xav tau ntawm cov khoos phis tawj thiab lwm yam khoom siv, thiab yuav maj mam hloov los ntawm kev hloov hluav taws xob.
