Mune yazvino DC transmission system, chete chinongedzo chekutumira ndiDC, iyo chizvarwa system uye yevatengi sisitimu ichiri AC. Pakupera kwekutumira mutsara wekutumira, iyo AC simba kubva kuAC sisitimu inotumirwa kune inogadzirisa kuburikidza neinoshandura shanduko muchiteshi chekushandura. Iyo inoshandura iyo yakakwira-voltage AC simba kuita yakakwira-voltage DC simba uye inotumira kune iyo DC transmission line..
