Qhov Tseem Ceeb Qhov txawv - Voltage Converter vs Transformer
Hauv kev xyaum, qhov hluav taws xob tau muab los ntawm ntau qhov sib txawv, feem ntau los ntawm lub zog loj. Cov khoom siv hluav taws xob, xws li AC lossis DC, muaj qhov tshwj xeeb lossis tus qauv tus nqi ntawm qhov hluav taws xob (piv txwv li, 230V hauv AC mains thiab 12V DC hauv lub tsheb roj teeb). Txawm li cas los xij, cov khoom siv hluav taws xob thiab hluav taws xob tsis tshua ua haujlwm hauv cov voltages tshwj xeeb; Lawv raug tsim los ua haujlwm ntawm qhov hluav taws xob los ntawm txoj kev hloov hluav taws xob hauv lub zog hluav taws xob. Voltage converters thiab transformers yog ob hom kev uas ua qhov kev hloov hluav taws xob no. Qhov sib txawv ntawm qhov sib txawv ntawm qhov hloov hluav taws xob thiab qhov hloov pauv yog qhov hloov pauv tsuas yog muaj peev xwm hloov AC voltages thaum lub zog hloov hluav taws xob tau tsim los hloov ntawm ob hom voltages.
YDab tsi yog Transformer?
A transformer hloov lub sijhawm sib txawv ntawm qhov voltage, feem ntau yog sinusoidal AC voltage. Nws ua haujlwm ntawm cov ntsiab lus ntawm electromagnetic induction.
Daim duab 01: Transformer
Raws li tau piav qhia hauv daim duab saum toj no, ob lub conductive (feem ntau yog tooj liab) coils, thawj thiab theem nrab, raug mob nyob ib ncig ntawm ib qho ferromagnetic core. Raws li Faraday txoj cai ntawm induction, qhov sib txawv ntawm qhov hluav taws xob ntawm lub hauv paus coil ua rau lub sijhawm sib txawv tam sim no uas khiav ncig lub hauv paus. Qhov no ua rau lub sijhawm sib txawv ntawm qhov sib nqus thiab qhov sib nqus flux raug xa mus rau hauv cov tub ntxhais mus rau theem ob. Lub sij hawm sib txawv flux tsim ib lub sij hawm-varying tam sim no nyob rau hauv lub thib ob kauj thiab yog li ntawd, lub sij hawm-varying voltage ntawm lub thib ob kauj.
Hauv qhov xwm txheej zoo tshaj plaws uas tsis muaj hluav taws xob poob tshwm sim, lub zog nkag mus rau sab xub ntiag yog sib npaug rau lub zog tso tawm ntawm qhov thib ob. Yog li, IpVp =IsVs
Tseem, Ip/Isss/N p
Qhov no ua rau qhov kev hloov pauv hloov hluav taws xob sib npaug rau qhov piv ntawm tus lej hloov.
VsVp=Ns/Np
Piv txwv li, 230V / 12V transformer muaj qhov sib piv ntawm 230/12 thawj rau theem nrab.
Hauv kev xa hluav taws xob, qhov hluav taws xob tsim hluav taws xob ntawm cov chaw tsim hluav taws xob yuav tsum tau nce mus ua kom qhov kev sib kis tam sim no qis, yog li ua rau lub zog poob qis. Ntawm substations thiab cov chaw faib khoom, qhov hluav taws xob tau nqis mus rau theem faib. Ntawm qhov kawg daim ntawv thov zoo li lub teeb LED, lub mains AC voltage yuav tsum tau hloov mus rau li 12-5V DC. Step-up transformers thiab step-down transformers yog siv los tsa thiab txo cov thawj sab voltage mus rau theem nrab, feem.
Dab tsi yog qhov Voltage Converter?
Voltage conversion tuaj yeem ua tau ntau yam xws li AC rau DC, DC rau AC, AC rau AC thiab DC rau DC. Txawm li cas los xij, DC rau AC converters feem ntau hu ua inverters. Txawm li cas los xij, tag nrho cov converters thiab inverters no tsis yog ib qho khoom siv xws li transformers, tab sis yog hluav taws xob circuits. Cov no yog siv los ua cov khoom siv hluav taws xob sib txawv.
AC to DC Converters
Cov no yog hom kev hloov hluav taws xob ntau tshaj plaws. Cov no yog siv rau hauv cov khoom siv fais fab ntawm ntau yam khoom siv los hloov AC mains voltage rau DC voltage rau hluav taws xob circuitry.
DC rau AC Converter lossis Inverter
Cov no feem ntau yog siv rau hauv kev tsim hluav taws xob rov qab los ntawm cov txhab nyiaj roj teeb thiab lub hnub ci photovoltaic. DC voltage ntawm PV panels los yog roj teeb yog inverted rau AC voltage los muab lub mains fais fab system ntawm lub tsev los yog ib lub tsev lag luam.
Daim duab 02: Yooj yim DC rau AC converter
AC to AC Converter
Hom kev hloov hluav taws xob no yog siv los ua cov khoom siv mus ncig; lawv kuj tau siv nyob rau hauv lub hwj chim mov units ntawm cov khoom siv ua rau ntau lub teb chaws. Txij li qee lub tebchaws xws li Asmeskas thiab Nyij Pooj siv 100-120V hauv lub teb chaws daim phiaj thiab qee qhov zoo li UK, Australia siv 220-240V, cov chaw tsim khoom siv hluav taws xob xws li TVs, tshuab ntxhua khaub ncaws, thiab lwm yam. siv hom hluav taws xob hloov hluav taws xob hloov hluav taws xob hloov hluav taws xob. mains mus rau qhov sib piv AC voltage ua ntej hloov mus rau DC hauv qhov system. Cov neeg taug kev mus los ntawm ib lub tebchaws mus rau lwm lub tebchaws yuav xav tau kev hloov pauv mus txawv tebchaws rau cov tebchaws sib txawv los ua lawv lub khoos phis tawj thiab lub xov tooj ntawm tes hloov mus rau lub nroog cov kab hluav taws xob hluav taws xob.
YDC to DC Converter
Hom kev hloov hluav taws xob no yog siv hauv lub tsheb fais fab adapters los khiav lub xov tooj ntawm tes thiab lwm lub tshuab hluav taws xob ntawm lub tsheb roj teeb. Txij li thaum lub roj teeb feem ntau tsim 12V DC, cov khoom siv yuav tau hloov qhov voltage ntawm 5V mus rau 24V DC nyob ntawm qhov yuav tsum tau ua.
Topology siv nyob rau hauv cov converters thiab inverters tej zaum yuav txawv ntawm ib tug mus rau lwm tus. Nyob ntawd, lawv tuaj yeem siv cov tshuab hloov pauv thiab hloov cov hluav taws xob siab mus rau qis dua. Piv txwv li, nyob rau hauv ib tug linear DC fais fab mov, ib tug transformer yog siv nyob rau hauv lub tswv yim los txo cov AC mains mus rau ib tug xav tau. Txawm li cas los xij, muaj cov kev siv hluav taws xob tsawg tsawg thiab. Hauv transformer-tsawg topology, DC voltage (txawm los ntawm cov tswv yim los yog hloov los ntawm AC) yog hloov mus rau thiab tawm los ua ib tug high-frequency pulsed -DC teeb liab. Lub sijhawm qhib-tawm piv txhais cov zis DC voltage theem. Qhov no tuaj yeem suav tau tias yog kev hloov pauv hloov pauv. Tsis tas li ntawd, buck converters, boost converts thiab buck-boost converters yog ua hauj lwm nyob rau hauv converting no pulsating DC voltage mus rau ib tug xav tau siab dua los yog tsawg voltage. Cov hom converters no tsuas yog cov hluav taws xob hluav taws xob ua los ntawm transistors, inductors, thiab capacitors.
Txawm li cas los xij, cov qauv tsim koom nrog hauv cov khoom siv hluav taws xob tsawg thiab cov khoom siv hluav taws xob hloov pauv uas siv cov khoom sib piv me me yog pheej yig dua los tsim. Ntxiv mus, lawv cov kev ua tau zoo dua thiab qhov loj thiab qhov hnyav tsawg dua.

Summary – Voltage Converter vs Transformer
Transformers thiab voltage converters yog ob hom fais fab converter li. Thaum lub tshuab hluav taws xob yog ib qho khoom siv nyob ib leeg, cov khoom siv hluav taws xob yog cov hluav taws xob hluav taws xob uas ua los ntawm cov khoom siv hluav taws xob, inductors, capacitors, thiab qee zaum txawm tias transformers thiab. Voltage converters tuaj yeem siv nrog DC lossis AC input los hloov lawv mus rau AC lossis DC. Tab sis transformers tsuas tuaj yeem muaj cov tswv yim ntawm AC voltages. Qhov no yog lub ntsiab sib txawv ntawm voltage converter thiab transformer.
