Mos pibyog ib qho tshiab lub cev muaj zog tswj cov cuab yeej uas sib txuas lub cev muaj zog pib, muag muag, lub teeb thauj khoom txuag hluav taws xob thiab ntau yam kev tiv thaiv.Nws lub ntsiab yog tsim los ntawm peb-theem rov qab paralleled thyristors thiab cov hluav taws xob tswj Circuit Court txuas nrog hauv series ntawm lub hwj chim mov thiab lub cev muaj zog tswj.Siv cov kev sib txawv los tswj lub kaum sab xis conduction ntawm peb-theem paralleled thyristors kom cov input voltage ntawm cov tswj lub cev muaj zog hloov raws li cov kev xav tau sib txawv, thiab cov haujlwm sib txawv tuaj yeem ua tiav.

Nrog rau kev nce ntxiv ntawm cov motors loj (5000kW ~ 60000kW) hauvcov tuam txhab loj thiab cov khoom siv, pib txoj kev loj-scale motors muajtau attracted ntau thiab ntau.Vim tias qhov kev ua haujlwm qis ntawm cov khoom pib ua kua tsis tuaj yeem ua tau raws li qhov kev xav tau ntawm lub tshuab muaj peev xwm loj, daim ntawv thov ntawm thyristor hom (khoom hauv lub xeev) cov khoom muag muag tau pib nce.Thiab ces switching transformer-hom mos pib li thiab magnetic saturation reactors (magnetically tswj) pib li thiab zaus hloov dua siab tshiab pab kiag li lawm yog ntau thiab ntau siv rau mos pib motors.Tam sim no, cov khoom pib ua kua feem ntau yog siv hauv cov motors me me (hauv qab 5000kW).Thiab thyristor seriessoft starterfeem ntau yog siv rau hauv lub cev muaj zog siab (ntau tshaj 5000KW).
