Dab tsi yog inverter?
Lub Inverter hloov kho DC Fais (roj teeb, cia roj teeb) rau hauv AC fais fab (feem ntau 2Hz sine yoj). Nws muaj cov inverter choj, tswj kev tswj hwm thiab lim dej.
Cias muab, ib qho inverter yog cov khoom siv hluav taws xob uas hloov voltage (12 lossis 248 volts lossis 48 volts) ncaj qha rau hauv 220 volts hloov chaw tam sim no. Vim tias peb feem ntau siv 220-volt hloov tshiab tam sim no, thiab inverter ua nyob rau hauv qhov rov qab los, li no lub npe.
Dab tsi yog asine yoj inverter
Inverters tuaj yeem raug cais raws li lawv cov kev tawm tsam cov zis, a. muab faib ua cov xwm txheej khoob khoob khoob, b. hloov kho dej inverters thiab c. sine dej inverters.
Yog li ntawd, lub ntsiab lus ntawm sine yoj inverter yog ib qho inverter uas nws cov zis WaveForm yog Sine yoj.
Nws qhov zoo dua yog tias cov zis WaveTormform yog qhov zoo, cov zis yog tsawg heev, thiab nws cov txiaj ntsig WaveTorm yog qhov yooj yim sib xws nrog AC WEBSFORFIC ntawm cov kab sib chaws Mains. Qhov tseeb, qhov zoo ntawm AC fais fab muab los ntawm cov zoo heevsine yoj invertersiab dua li ntawm kab sib chaws. Sine yoj inverter muaj kev cuam tshuam me me hauv xov tooj cua, cov khoom siv sib txuas lus, muaj peev xwm ua tau daim ntawv thov kev hloov kho, thiab tag nrho cov tshuab muaj kev ua haujlwm siab; Nws qhov tsis zoo yog tias txoj kab thiab txheeb ze kho qhov yoj caw cov inverter yog cov khoom siv, muaj cov thev naus laus zis thiab yog kim.
Nws ua haujlwm li cas?
Ua ntej qhia txog kev ua haujlwm ntawm lubsine yoj inverter, Ua ntej qhia txog txoj cai ua hauj lwm ntawm inverter.
Lub inverter yog DC rau AC transformer, uas yog tus txheej txheem ntawm voltage inversion nrog converter. Lub Converter hloov cov pob hluav taws xob ntawm lub hwj chim sib tshooj rau hauv lub tsev kawm ntawv ruaj khov los ntawm 12v dc voltage tso zis rau hauv lub siab-voltage ac; Ob qho tib si feem tseem siv cov ntau zaus siv cov txheej txheem dav dav dav (PWM) cov txheej txheem. Nws qhov tseem ceeb yog PWM kev sib xyaw ua ke xws li, tus adapter siv UC3842, thiab Inverter siv TL5001 Chip. Cov hauj lwm voltage muaj ntau ntawm TL5001 yog 3.6 ~ 40v, thiab nws yog qhov chaw tsim hluav taws xob, ib qho hluav taws xob tiv thaiv kev tiv thaiv kev tswj hwm, kev tiv thaiv hluav taws xob tsawg tsawg.
Cov tswv yim interface: Muaj 3 lub cim hauv cov lus qhia tawm, 12v DC Cov Lus Qhia VIN, ua hauj lwm pab voltage enb thiab vaj huam sib luag tam sim no kev tswj teeb liab tsaus. Vin yog muab los ntawm cov adapter, enb voltage yog muab los ntawm mcu ntawm motherboard, nws tus nqi yog 0 lossis 3v, lub inverter yog nyob rau hauv ib txwm ua haujlwm; Thaum dim voltage muab los ntawm lub rooj loj loj, nws cov kev hloov pauv ntau ntawm 0 thiab 5V. Txawv Dim qhov tseem ceeb tau pub rov qab rau lub sijhawm tiv thaiv lub davhlau ya nyob twg ntawm PWM maub los, thiab cov khoom siv tam sim no, thiab cov khoom tam sim no los ntawm lub inverter yuav yog qhov sib txawv. Tus me dua tus nqi qis dua, cov me me tso tawm tshiab ntawm inverter. Loj.
Cov Khoom Siv Hluav Taws Xob Pib: Thaum enb yog qib siab, nws tau tawm ntawm cov hluav taws xob ntau rau teeb lub vaj huam sib luag backlight raj.
PWM maub los: nws muaj cov haujlwm hauv qab no: Cov Kev Tiv Thaiv Sab Hauv, Oscillator Kev Tiv Thaiv, Kev Tiv Thaiv Hauv Underventage, thiab tso tawm cov khoom siv luv luv.
DC hloov dua siab tshiab: Qhov ntsuas kev hloov kho Circuit Court yog muaj ntawm Mos Transping Tube thiab lub zog cia inductor. Cov tshuaj nkag tau yog nthuav dav los ntawm lub laub-rub ampleger thiab tom qab ntawd drives ua rau lub inductor, kom lwm qhov kawg ntawm inductor tuaj yeem tau txais AC voltage.
LC oscillation thiab tso zis Circuit Court: Nco ntsoov 1600V voltage yuav tsum muaj lub teeb los pib, thiab txo cov hluav taws xob mus rau 800v tom qab lub teeb tau pib.
Cov zis hluav taws xob tawm tswv yim: thaum lub nra ua haujlwm, tus qauv voltage yog pub rov qab cov hluav taws xob tawm ntawm kuv inverter.
(Ua kab sine yoj Circmorram)
Qhov sib txawv ntawm cov sine yoj inverter thiab cov khoom siv hluav taws xob zoo tib yam yog qhov kev cuam tshuam dinetort thiab kev cuam tshuam nrog cov suab sib txuas lus tsis muaj zog, yog li cov suab sib txuas lus tsis muaj tsawg, kev tiv thaiv kev tiv thaiv tsis muaj , thiab qhov ua tau zoo tag nrho yog siab.
Vim li cas vim li cassine yoj invertertuaj yeem tso tawm ua tiav Sine Wrour yog vim tias nws siv SpwM Technology uas yog ntau dua li ntawm PWM thev naus laus zis.
Lub hauv paus ntsiab lus ntawm SPWM yog ua raws li txoj ntsiab cai uas Pulses ua raws sijhawm, yog lub sijhawm pulses tau sib npaug, thiab cov pulses no tuaj yeem yog kwv yees.
SPICH sib piv cov duab peb sab nrog tsau cov nqi (xws li hloov chaw tuab (pulse) ntawm cov mem tes (pulse Cov ntaub ntawv cuav yoj yoj ntawm lub cuab yeej. Lub amplitude thiab zaus ntawm cov ntaub ntawv sine yoj tau hloov kho kom tsim cov tshuaj txhuam hniav sib npaug nrog cov sine yoj nrog cov hluav taws xob sib txawv thiab ntau zaus.
