Lub keeb kwm yav dhau ntawm kev yug me nyuam ntawm zaus hloov tshuab yog qhov kev thov dav rau kev tswj tsis tau nrawm ntawm AC motors. Cov txheej txheem DC ceev tswj kev siv tshuab yog txwv los ntawm nws qhov loj me thiab siab tsis ua haujlwm.
Tom qab 60s ntawm lub xyoo pua 20th, thyristors thiab lawv cov khoom kho dua tshiab tau siv dav hauv cov khoom siv hluav taws xob hluav taws xob. Txawm li cas los xij, nws txoj kev tswj hwm kev ua tau zoo yog deb ntawm qhov ua tau raws li qhov xav tau. Nyob rau hauv 1968, high-tech enterprises sawv cev los ntawm Danfoss pib loj zus tau tej cov zaus converters, qhib ib tug tshiab era ntawm zaus converter industrialization.
Txij li thaum xyoo 70s ntawm lub xyoo pua 20th, kev tshawb fawb ntawm pulse width modulation variable voltage conversion (PWM-VVVF) ceev txoj cai tau ua ib tug breakthrough, thiab kev txhim kho ntawm microprocessor technology tom qab 80s ntawm lub xyoo pua 20th tau ua kom yooj yim rau kev siv ntau yam optimization. algorithms.
Nyob rau hauv nruab nrab thiab lig 80s ntawm lub xyoo pua 20th, VVVF inverter technology nyob rau hauv tsim lub teb chaws xws li lub tebchaws United States, Nyiv, Lub teb chaws Yelemees, thiab Britain tau muab tso rau hauv kev xyaum, thiab cov khoom tau muab tso rau hauv kev ua lag luam thiab dav siv. Cov inverters ntxov tshaj plaws yuav tau tsim los ntawm cov neeg Nyij Pooj uas tau yuav daim ntawv pov thawj British. Txawm li cas los xij, Tebchaws Asmeskas thiab Lub Tebchaws Yelemees tso siab rau qhov zoo ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov khoom siv high-end sai sai txeeb lub khw.
Piv nrog rau txoj kev loj hlob ntawm txawv teb chaws inverters, daim ntawv thov ntawm inverters nyob rau hauv Tuam Tshoj pib lig, thiab nws tsis tau nthuav dav mus txog rau thaum xaus ntawm 90s ntawm lub xyoo pua 20th. Txoj kev loj hlob ntawm domestic zaus hloov dua siab tshiab thev naus laus zis tuaj yeem ua tiav raws li: tag nrho cov thev naus laus zis ntawm kev hloov pauv zaus yog rov qab, thiab muaj qhov sib txawv loj piv nrog cov kev ua tiav qib siab ua los ntawm cov teb chaws txawv teb chaws hauv kev tshawb fawb kev hloov pauv ceev; Tam sim no, cov khoom siv hluav taws xob tseem ceeb uas yuav tsum tau ua hauv kev tsim cov tshuab hluav taws xob tsis tuaj yeem tsim los ntawm cov tuam txhab tsim khoom hauv tsev, ua rau peb cov thev naus laus zis tseem ceeb raug xa mus rau txawv teb chaws thiab yuav tsum cia siab rau kev xa khoom; Cov khoom tseem ceeb yog concentrated hauv cov khoom siv hluav taws xob tsawg thiab cov khw muag khoom qis. Vim tias cov khoom lag luam tsis tshua muaj kev ntseeg siab thiab cov txheej txheem, cov khoom siv hluav taws xob hauv tsev tam sim no feem ntau yog tsom mus rau qhov tsis tshua muaj hluav taws xob thiab kev ua haujlwm ntawm kev ua lag luam, thiab kev ua lag luam siab thiab lub zog hluav taws xob feem ntau yog nyob ntawm cov tuam txhab txawv teb chaws loj.
Tom qab nkag mus rau hauv lub xyoo pua 21st, domestic inverters tau maj mam nce thiab maj mam txeeb lub lag luam high-end. Shanghai thiab Shenzhen tau dhau los ua tus thawj coj ntawm kev txhim kho cov khoom siv hluav taws xob hauv tsev.
