I-inverter yezigaba ezintathu ukuguqulwa kwesigaba se-ac voltage, okuyi-AC380V, ugesi wezigaba ezintathu wakhiwe amafrikhwensi amathathu afanayo, i-amplitude, umehluko wesigaba esingu-120 ° komunye nomunye ngokushintshana ngokulinganayo kwamandla kagesi.Ingabe incazelo i-inverter yezigaba ezintathu iguqula i-dc ibe yi-ac power converter, isimiso esiyisisekelo se-SPWM, ukwakhiwa kwehadiwe yemodyuli yamandla amane wesigaba esisodwa, isifunda sohlobo lwebhuloho lezigaba ezintathu, ibhuloho phakathi kokuphumayo nokuhlanganiswa komthwalo wesici sokuhlunga esiphansi, Isifunda sokulawula sinomthombo wesignali emibili, igagasi elingunxantathu liguquliwe i-amplitude modulation wave generator, i-sine wave generator, i-Sine wave ukuze isebenzise ukuguquguquka kwegagasi elingunxantathu.
