Kev tsim kho hluav taws xob cua sov Tube Electroplating Fais Fab Electronics Technology
Txoj kev loj hlob ntawm kev siv hluav taws xob niaj hnub siv tshuab hluav taws xob yog hloov los ntawm cov khoom siv hluav taws xob ib txwm siv, uas tsom mus rau cov cuab yeej siv hluav taws xob tsawg rau cov khoom siv hluav taws xob niaj hnub, uas tsom mus rau kev siv tshuab hluav taws xob ntau. Lub tshuab hluav taws xob hluav taws xob tau pib los ntawm cov khoom siv silicon rectifier nyob rau xyoo 1950s thiab thaum ntxov 1960s. Nws txoj kev loj hlob tau dhau los ntawm lub sijhawm rectifier, inverter era, thiab zaus converter era, thiab tau txhawb nqa kev siv hluav taws xob hluav taws xob thev naus laus zis hauv ntau qhov chaw tshiab. Cov khoom siv hluav taws xob semiconductor sib xyaw tsim nyob rau xyoo 1980s thiab thaum ntxov 1990s, sawv cev los ntawm lub zog MOSFETs thiab IGBTs, uas ua ke nrog high-frequency, high-voltage, thiab high tam sim no, qhia tias ib txwm siv hluav taws xob hluav taws xob siv hluav taws xob tau nkag mus rau lub zog hluav taws xob niaj hnub.
1.1 Rectifier era
Lub zog hluav taws xob muaj hluav taws xob siab yog muab los ntawm lub zog zaus (50Hz) alternators, tab sis kwv yees li 20 feem pua ntawm cov hluav taws xob tau siv rau hauv daim ntawv tam sim no. Cov khoom siv feem ntau yog electrolysis (cov hlau tsis muaj hlau thiab cov khoom siv tshuaj lom neeg yuav tsum tau siv hluav taws xob ncaj qha), traction (hluav taws xob locomotives, hluav taws xob uas tau tsav diesel locomotives, subway locomotives, nroog trolleys, thiab lwm yam), thiab kev xa ncaj qha tam sim no (steel dov, ntawv ua. , thiab lwm yam). Siab zog silicon rectifiers tuaj yeem hloov lub zog zaus hloov tam sim no mus rau qhov tam sim no ncaj qha. Yog li ntawd, nyob rau xyoo 1960 thiab 1970s, kev txhim kho thiab kev siv lub zog siab zog silicon rectifiers thiab thyristors tau tsim zoo heev. Thaum lub sijhawm ntawd, muaj nthwv dej ntawm cov chaw tsim khoom loj silicon rectifier hauv Suav teb, thiab cov chaw tsim khoom ntawm cov khoom siv hluav taws xob ntawm silicon rectifiers ntawm txhua qhov ntau thiab tsawg hauv lub tebchaws yog cov khoom ntawm lub sijhawm ntawd.
1.2 Inverter era
Nyob rau xyoo 1970s, muaj kev kub ntxhov thoob ntiaj teb, thiab qhov sib txawv ntawm kev ceev ceev ntawm AC lub cev muaj zog tau tsim kho sai heev vim tias nws cov txiaj ntsig zoo heev txuag hluav taws xob. Cov thev naus laus zis tseem ceeb ntawm kev tswj hwm qhov sib txawv ntawm qhov ceev yog hloov pauv tam sim no rau hauv 0 ~ 100Hz alternating tam sim no. Los ntawm xyoo 1970 mus txog rau xyoo 1980, nrog rau qhov nrov ntawm kev hloov pauv ceev ceev tswj cov cuab yeej, thyristor, lub zog loj loj transistor (GTR) thiab rooj vag rooj vag tig-tawm thyristor (GT0) siv rau high-power inverter los ua lub luag haujlwm ntawm cov khoom siv hluav taws xob hluav taws xob. lub sijhawm ntawd. Cov ntawv thov zoo sib xws muaj xws li high-voltage DC tso zis, static reactive zog dynamic them, thiab lwm yam. Lub sijhawm no, lub zog hluav taws xob hluav taws xob thev naus laus zis tuaj yeem ua tiav qhov kev hloov kho thiab hloov pauv, tab sis kev khiav hauj lwm zaus kuj tsawg, txwv rau qhov nruab nrab mus rau qhov tsawg zaus.
