Cov kev taw qhia txhim kho ntawm lub zog hluav taws xob niaj hnub siv tshuab hluav taws xob yog hloov ntawm cov tsoos hluav taws xob siv hluav taws xob, uas feem ntau cuam tshuam nrog kev siv tshuab hluav taws xob tsawg, hloov mus rau cov khoom siv hluav taws xob niaj hnub no, uas feem ntau cuam tshuam nrog high-frequency technology. Cov cuab yeej hluav taws xob lub zog hluav taws xob pib nrog silicon rectifier li hauv xyoo 1950 thiab thaum 1960s. Nws txoj kev loj hlob tau ua tiav qhov kev hloov ntawm cov rectifier, lub sijhawm inverter, thiab qhov hloov pauv lub zog hluav taws xob lub sijhawm, thiab tau tshaj tawm cov ntawv thov ntawm lub zog hluav taws xob thev naus laus zis hauv ntau cov teb tshiab. Lub zog hluav taws xob semiconductor cov khoom sib txuas ua ke sawv cev los ntawm lub zog hluav taws xob MOSFETs thiab IGBTs tau tsim nyob rau xyoo 1980s thiab thaum ntxov xyoo 1990, uas muaj kev sib xyaw loj, qhov hluav taws xob loj thiab qhov siab tam sim no, qhia tau tias lub tshuab hluav taws xob siv hluav taws xob tau nkag mus rau lub zog hluav taws xob niaj hnub no.
1. Lub sijhawm ntawm rectifiers
Kev lag luam hluav taws xob muaj hluav taws xob ntau yog muab los ntawm lub zog hluav taws xob (50Hz) kev hloov pauv, tab sis kwv yees li 20% ntawm hluav taws xob tau noj nyob rau hauv daim ntawv ntawm DC, feem ntau cov hluav taws xob feem ntau yog electrolysis (non-ferrous hlau thiab tshuaj lom neeg cov ntaub ntawv xav tau DC electrolysis) ), traction (hluav taws xob Locomotives, tsav hluav taws xob diesel locomotives, subway locomotives, nroog tsheb npav tsheb npav, thiab lwm yam) thiab DC tsav (steel dov, papermaking, thiab lwm yam) hauv peb qhov chaw loj. High-power silicon rectifiers tuaj yeem muaj peev xwm hloov tau lub zog hluav taws xob ntau hloov tam sim no mus rau qhov ncaj qha tam sim no. Yog li no, nyob rau xyoo 1960 thiab 1970s, kev tsim kho thiab siv ntawm cov muaj zog siab silicon rectifiers thiab thyristors tau tsim kho heev. Lub sijhawm ntawd, muaj kev hloov siab ntawm kev lag luam loj silicon rectifier factories thoob plaws lub tebchaws. Nyob rau tam sim no, cov tshuab hluav taws xob loj thiab me me ua cov tsim cov tshuab ua kua roj silicon rectifiers hauv lub teb chaws yog cov khoom ntawm lub sijhawm ntawd.
2. Inverter era
Tau muaj kev kub ntxhov thoob ntiaj teb hauv xyoo 1970, thiab AC motors' zaus hloov dua siab tshiab hloov ceev nrawm nrawm vim lawv qhov pom zoo txuag hluav taws xob. Lub thev naus laus zis tseem ceeb ntawm kev hloov pauv ntawm kev hloov ceev ceev yog kom rov qab hloov ncaj qha rau kev hloov tam sim no ntawm 0 ~ 100Hz. Los ntawm xyoo 1970 mus rau 1980s, nrog kev tshaj tawm ntawm cov kuj tsis paub meej ceev tswj cov cuab yeej, thyristors, loj zog fais fab transistors (GTR) thiab lub rooj vag tig-thyristors (GT0) rau cov muaj zog siv hluav taws xob ua cov neeg tawm tsam ntawm cov khoom siv hluav taws xob hauv lub sijhawm ntawd. Cov ntawv thov zoo sib xws nrog cov hluav taws xob ntau ntawm DC cov txiaj ntsig, cov hluav taws xob zoo li qub hloov kho lub zog, thiab lwm yam Lub sijhawm no, lub tshuab hluav taws xob hluav taws xob tau ua tiav qhov kev ua kom tiav thiab rov ua dua, tab sis kev ua haujlwm tsawg tsawg, tsuas yog tsawg tsawg xwb.
3. Lub caij nyoog ntawm cov zis hluav taws xob sib txawv
Kev hloov pauv ntawm lub zog hluav taws xob hloov hloov sib hloov tam sim no hauv cov hluav taws xob los ntawm AC → DC → AC, thiab tawm cov ntshiab sine nthwv dej. Cov zis zaus thiab qhov ntsuas hluav taws xob tau kho nyob rau hauv qee qhov kev ntsuas. Nws yog qhov txawv ntawm qhov hloov dua siab tshiab hloov ceev ceev siv rau lub zog tswj lub zog, thiab nws kuj txawv ntawm qhov zoo tib yam AC stabilized fais fab mov. Qhov zoo tagnrho AC fais fab mov yog tus yam ntxwv lub cev, qhov ruaj khov voltage, xoom sab hauv tsis kam, thiab ntshiab sine yoj (tsis muaj qhov tsis sib xws) hauv qhov voltage voltage.
Nyob rau xyoo 1980, cov khoom siv hluav taws xob hloov pauv hluav taws xob feem ntau tau tsim los ntawm cov twj paj nruag me me hauv Japanese. Cov khoom siv fais fab ntawm hom ntsuas no feem ntau ua los ntawm kev ua kom nrov nrov. Tom qab xyoo 1980, lawv tau qhia mus rau Tuam Tshoj av mus txog Taiwan. Cov yam ntxwv ntawm lub hwj huam hluav taws xob nyob rau lub sijhawm no yog: tsis tshua muaj zog, ua haujlwm zoo, thiab kev ua kom tau zoo.
Xyoo 1980, Suav teb lub tebchaws tau pib ntawm txoj kev hloov kho thiab qhib. Nyob rau theem no, Tuam Tshoj' s cov khoom ntshuam thiab khoom siv maj mam nce ntxiv, tshwj xeeb tshaj yog cov khoom xa tawm ntawm cov khoom siv hluav taws xob xws li microwave ncu thiab lub tshuab cua txias. Yog li ntawd, cov khoom siv fais fab inverter siab tau tsim nyog rau kev kuaj. Rau cov kev xav tau ntawm ntu no ntawm kev ua lag luam, cov khoom lag luam qub tsis tuaj yeem ntsib, yog li cov tuam txhab hluav taws xob nrhiav cov tshuab tshiab los nthuav lub zog ntawm lub zog siv. Raws li cov txheej txheem kev qhia thiab khoom siv hluav taws xob thaum lub sijhawm, txoj kev txhim kho tsuas yog ob txoj hauv kev. Ntawm ib sab, cov hom siv lead ua tau khaws cia tsis hloov pauv, thiab ntau lub tshuab tau txuas nrog hauv kev sib txig rau qhov muaj peev xwm nthuav dav; lwm txoj kev yog siv fais fab siv lead ua qauv.
