Nrog rau kev loj hlob sai ntawm niaj hnub hluav taws xob hluav taws xob tshuab hluav taws xob thiab kev tswj hwm kev siv tshuab computer, thev naus laus zis kiv puag ncig ntawm hluav taws xob tsav tau nce.Ac ceev tswj es tsis txhob DC ceev tswj, computer digital tswj es tsis txhob analog tswj tau dhau los ua ib qho kev loj hlob.Ac lub cev muaj zog hloov pauv ceev kev tswj hwm yog lub ntsiab lus tseem ceeb kom txuag tau lub zog, txhim kho cov txheej txheem tsim khoom, txhim kho cov khoom zoo, thiab txhim kho qhov chaw ua haujlwm.Kev tswj hwm qhov sib txawv zausNrog nws cov kev ua haujlwm siab, lub zog muaj zog, nrog rau kev tswj hwm kev ceev nrawm thiab kev ua haujlwm braking thiab ntau lwm yam zoo yog suav tias yog txoj cai ceev tshaj plaws.
Yav dhau loshigh-voltage inverter, muaj li ntawm thyristor rectifier, thyristor inverter thiab lwm yam khoom siv, muaj ntau yam shortcomings, loj harmonics, thiab muaj feem xyuam rau lub hwj chim daim phiaj thiab lub cev muaj zog.Nyob rau hauv xyoo tas los no, qee cov khoom siv tshiab tau tsim los hloov qhov xwm txheej no, xws li IGBT, IGCT, SGCT thiab lwm yam.Lub siab voltage inverter tsim los ntawm lawv muaj kev ua tau zoo heev thiab tuaj yeem paub PWM inverter thiab txawm tias PWM rectification.Tsis tsuas yog cov harmonics me me xwb, tab sis kuj yog lub hwj chim zoo heev
Ac zaus hloov dua siab tshiab tswj kev siv tshuab yog kev sib xyaw ua ke ntawm cov hluav taws xob muaj zog thiab tsis muaj zog, kev siv tshuab thiab hluav taws xob sib xyaw ua ke, tsis yog tsuas yog cuam tshuam nrog kev hloov pauv ntawm lub zog loj (rectification, inverter), tab sis kuj cuam tshuam nrog kev sau cov ntaub ntawv, kev hloov pauv thiab kev sib kis. , yog li nws yuav tsum tau muab faib ua lub zog thiab tswj ob ntu.Tus qub yuav tsum daws cov teeb meem kev lag luam uas muaj feem xyuam rau cov hluav taws xob siab thiab cov hluav taws xob siab, thiab tom kawg yuav tsum daws cov teeb meem kev tswj hwm software thiab kho vajtse.Yog li ntawd, yav tom ntej high voltage zaus hloov dua siab tshiab kev tswj technology kuj yuav tsim nyob rau hauv ob yam no, nws lub ntsiab kev ua tau zoo yog:
(1) Covhigh voltage hloov pauv zausyuav tsim nyob rau hauv cov kev taw qhia ntawm siab zog, miniaturization thiab lub teeb yuag.
(2) Covsiabvoltage hloov pauv zaus tsavyuav tsim nyob rau hauv ob qho kev qhia: ncaj qha ntaus ntawv high voltage thiab ntau superposition (device series thiab unit series).
(3) Cov khoom siv hluav taws xob tshiab uas muaj hluav taws xob ntau dua thiab muaj zog dua tam sim no yuav raug siv rau hauvhigh voltage kuj sib txawv zaus tsav
(3) Nyob rau theem no, IGBT, IGCT, SGCT tseem yuav ua lub luag haujlwm tseem ceeb, SCR, GTO yuav tawm ntawm kev lag luam inverter.
(4) Daim ntawv thov ntawm vector tswj, flux tswj thiab ncaj qha torque tswj tshuab yam tsis muaj kev ceev sensor yuav ua kom paub tab.
(5) Ua tiav kev paub txog digitalization thiab automation: parameter self-set technology;Txheej txheem self-optimization technology;Fault self-diagnosis technology.
(6) Daim ntawv thov ntawm 32-ntsis MCU, DSP thiab ASIC pab kiag li lawm, kom ua tiav siab precision thiab multi-function inverter.
(7) Cov kev txhawb nqa ntsig txog kev lag luam tau txav mus rau qhov tshwj xeeb thiab kev loj hlob loj, thiab kev sib faib ntawm kev ua haujlwm yuav pom tseeb dua.
