Isigaba esithathu inverter kukuguqulwa kwesigaba sombane we-ac, oko kukuthi i-AC380V, umbane wesigaba sesithathu senziwe ngamaqutyana amathathu afanayo, i-amplitude, umahluko wesigaba se-120 ° omnye komnye ngokutshintshiselana ngokulinganayo kwamandla ombane. i-inverter yesigaba sesithathu iguqula i-dc kwi-ac converter yamandla, umgaqo osisiseko we-SPWM, i-architecture ye-hardware yemodyuli yamandla emine yesigaba esisodwa, isiphaluka sohlobo lwebhulorho yesigaba sesithathu, ibhulorho phakathi kwemveliso kunye nokudibanisa komthwalo we-filter element ephantsi, Isekethe yolawulo inemithombo yomqondiso emibini, igagasi elingunxantathu lilungisiwe i-amplitude modulation wave generator, i-sine wave generator, iSine wave ukwenza ukusetyenziswa kwemodulation yamaza unxantathu.
