Uku-lokaci inverter ne hira da ac irin ƙarfin lantarki lokaci, wato AC380V, uku-lokaci lantarki da aka yi sama da uku guda mita, amplitude, lokaci bambanci 120 ° da juna bi da bi daidai musayar lantarki potential.Is the definition of inverter uku-lokaci yana jujjuya dc zuwa mai sauya wutar lantarki, ainihin ka'idar SPWM, kayan gini na kayan gini na ƙirar wutar lantarki guda huɗu, nau'in gada mai nau'in gada uku, gada tsakanin fitarwa da haɗaɗɗen nau'ikan tacewa mara ƙarfi, Da'irar sarrafawa tana da tushen siginar guda biyu, igiyar triangular tana kafaffen janareta na daidaitawa na daidaitawa, janareta na sine wave, Sine wave don yin amfani da daidaitawar motsin triangle.
