Lub substrate ntawm cov khoom siv hluav taws xob hluav taws xob tau hloov los ntawm Si (silicon) mus rau SiC (silicon carbide), muab lub zog tshiab hluav taws xob cov khoom siv hluav taws xob zoo ntawm cov hluav taws xob tsis zoo, kev siv hluav taws xob tsawg, thiab kub tsis kam. Qhov no kuj tau ua rau kev tsim cov khoom me me, siab dua - muaj peev xwm tsav tsheb; cov hlau nplaum ruaj khov motors tseem tab tom txhim kho. Nrog rau qhov nrov tshaj plaws ntawm IT thev naus laus zis, kev hloov pauv zaus tsav (VFD) muaj feem xyuam nrog cov thev naus laus zis tau txhim kho sai, thiab kev txhim kho yav tom ntej yuav tsom mus rau cov hauv qab no:
Network txawj ntse
Intelligent VFDs yuav tsum muaj qhov ntsuas tsawg tsawg thaum siv, muaj tus kheej - muaj peev xwm kuaj mob, thiab muaj kev ruaj ntseg, kev ntseeg siab, thiab kev ua tau zoo.
Tam sim no, VFDs tshiab ntawm kev ua lag luam tau tsim - hauv kev sib txuas thiab muab ntau yam kev sib txuas lus sib txuas, txhawb nqa ntau yam kev sib txuas lus. Lawv tuaj yeem tswj tau thiab ua haujlwm ntawm lub khoos phis tawj keyboard, thiab tuaj yeem sib txuas nrog ntau lub tshav dav hlau, ua kom muaj kev sib koom tes ntawm ntau VFDs, lossis txawm tias muaj kev tswj hwm VFD thiab kev tswj hwm rau tag nrho lub Hoobkas.
Tshwj xeeb thiab kev koom ua ke
Qhov tshwj xeeb ntawm VFD kev tsim khoom tso cai rau kev txhim kho kev ua tau zoo hauv cov haujlwm tshwj xeeb, xws li VFDs rau cov kiv cua thiab cov twj tso kua mis, siab VFDs rau elevators, siab VFDs rau hoisting machinery, thiab siab VFDs rau kev tswj nruj. Tsis tas li ntawd, muaj kev sib koom ua ke ntawm VFDs nrog lub cev muaj zog, ua rau VFD yog ib feem ntawm lub cev muaj zog, ua rau me me thiab tswj tau yooj yim dua.
Kev ua haujlwm siab
Nrog rau kev txhim kho kev tswj hwm txoj kev xav xws li vector tswj thiab tswj lub zog, thiab kev siv lub siab - ceev cov teeb liab digital processors, kev ua haujlwm ntawm VFDs yuav txuas ntxiv txhim kho. Txoj kev loj hlob ntawm kev siv tshuab sensorless vector tswj tau tso tawm cov tshuab zaus hloov pauv los ntawm kev txwv ntawm cov khoom siv kho vajtse- raws li kev ntsuas lub cev muaj zog, ua rau cov kab ke me me.
Nce Digitalization
Tau txais txiaj ntsig los ntawm kev nce qib hauv kev siv tshuab computer, kev tswj hwm qhov sib txawv yuav ua tiav kev sib koom ua ke ntawm AC ceev tswj cov tshuab thiab cov ntaub ntawv xov xwm, thaum tseem txhim kho kev ua haujlwm tag nrho. Tsis tas li ntawd, nrog kev nce qib ntawm AC lub cev muaj zog tswj txoj kev xav, cov tswv yim tswj kev sib raug zoo thiab cov algorithms tau dhau los ua qhov nyuaj, xav tau ntau qhov kev suav thiab chaw cia khoom. Tam sim no, tag nrho cov digital siab -kev ua tau zoo AC ceev tswj tshuab dav siv DSP chips.
Kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev ua qias tuaj -Kev Ua Haujlwm Dawb
Electromagnetic compatibility, harmonic suppression, thiab lub suab nrov ntawm lub cev muaj zog technologies rau VFDs yog tam sim no qhov tseem ceeb ntawm kev tsom xam. Kev cuam tshuam ib puag ncig ntawm VFDs tau dhau los ua qhov tseem ceeb. Ntau lub teb chaws twb tau tsim cov kev cai thiab cov qauv los txwv kev sib haum xeeb. Nrhiav cov kev daws teeb meem zoo los daws cov suab nrov thiab electromagnetic polluters ntawm zaus converters tau dhau los ua qhov tseem ceeb rau ntau tus kws tshawb fawb.
Hloov mus rau Cov Khoom Siv Hluav Taws Xob Tshiab
Cov roj hluav taws xob siv hluav taws xob los ntawm lub hnub ci thiab cua zog tam sim no tau tshwm sim los ua ib qho kev cog lus thev naus laus zis vim lawv cov nqi qis, uas qhia tau tias muaj peev xwm tshaj li cov khoom siv hluav taws xob. Cov yam ntxwv tseem ceeb ntawm cov cuab yeej tsim hluav taws xob no yog lawv lub peev xwm me me thiab faib qhov xwm txheej. Yav tom ntej zaus converters yuav tsum tau hloov mus rau cov tshiab zog qhov chaw, yuav tsum tau ob qho tib si high efficiency thiab tsawg zog noj. Nrog rau qhov kev xav tsis thoob ntawm txoj kev loj hlob hauv hluav taws xob hluav taws xob, microelectronics, thiab cov thev naus laus zis tswj niaj hnub, kev hloov pauv ceev ceev tswj thev naus laus zis kuj tau ua tiav sai. Qhov kev vam meej no tau tshwm sim nyob rau hauv qhov muaj peev xwm ntawm AC ceev tswj cov cuab yeej, kev ua haujlwm siab thiab ntau -functionality ntawm zaus converters, thiab lawv cov miniaturization.
