Ukusuka ku-AC kuye ku-DC, kusukela kufrikhwensi yamandla kuye kumafrikhwensi amaphakathi, bese kuya kubuchwepheshe obunelungelo lobunikazi (isixazululo sesistimu yebhasi ye-DC) obusetshenziswa ekukhiqizeni ngezinga elikhulu izimboni zesafire.Imikhiqizo isetshenziswa ezinqubweni ezihlukahlukene zokukhula kwesafire ezifana nendlela yokwenza amagwebu, indlela yokushintshanisa ukushisa kanye nendlela yemodi eqondisiwe.I-Injet iletha inani kanye nokuncintisana kumakhasimende ngokuqamba okusha okuqhubekayo, futhi izoqhubeka nokufaka isandla ekuthuthukisweni kwemboni.
