Njengesixhobo esingundoqo kwindawo yokutshaja isithuthi sombane, iimfumba zokutshaja ze-DC zisekelwe kumgaqo wokuguqula ngokufanelekileyo amandla atshintshayo akhoyo (AC) ukusuka kwigridi ukuya kumandla e-DC, anikezelwa ngokuthe ngqo kwiibhetri zesithuthi sombane, ukuqonda ukutshaja ngokukhawuleza. Le teknoloji ayenzi lula kuphela inkqubo yokutshaja, kodwa ikwaphucula ngokubonakalayo ukusebenza kakuhle kokutshaja, okuyindlela ebalulekileyo yokuqhubela phambili ukuthandwa kwezithuthi zombane. I-advanteji yeemfumba zokutshaja ze-DC ilele kubuchule bazo bokutshaja obusebenzayo, obunokunciphisa kakhulu ixesha lokutshaja kunye nokuhlangabezana nemfuno yomsebenzisi yokuzaliswa ngokukhawuleza. Kwangaxeshanye, iqondo layo eliphezulu lobukrelekrele lenza kube lula kubasebenzisi ukuba basebenze kwaye babeke iliso, nto leyo ephucula ukulungelwa kunye nokhuseleko lokutshaja. Ukongeza, ukusetyenziswa okubanzi kweemfumba ze-DC zokutshaja kwakhona kunceda ukukhuthaza ukuphuculwa kweziseko zombane zesithuthi kunye nokuthandwa kokuhamba okuluhlaza.
