Peb SVG Txee yog hloov tau yooj yim AC kis tau tus mob cov cuab yeej raws li kev tswj hwm hluav taws xob hluav taws xob tag nrho (IGBT). Nws siv cov cuab yeej hluav taws xob hloov hluav taws xob (VSC) thiab ua tiav cov khoom siv hluav taws xob muaj zog los ntawm PWM tswj.
Piv nrog rau SVCs ib txwm muaj, SVG muaj cov lus teb sai dua, siab dua, thiab kev tsim qauv ntau dua, ua rau nws yog ib qho tseem ceeb hauv cov phiaj xwm ntse thiab niaj hnub kev lag luam hluav taws xob zoo.
Txoj Cai Ua Haujlwm
● SVG ua rau cov thawj coj/lagging reactive tam sim no los ntawm kev tswj IGBT hloov ntawm PWM.
● Siv tam sim no reactive zog txoj kev xav rau tiag tiag - sij hawm them nyiaj.
