Advantages of HVDC over HVAC Power Transmission HVAC transmission requires a minimum of 3 conductors for 3-phase power transmission while in case of HVDC that can utilize the earth as the return path can use only 1 conductor for mono-polar transmission or 2 conductors for a bipolar transmission. It substantially decreases the overall cost of the transmission. Even so, the 3 conductors used for 3-phase supply can be used for HVDC ...

Basics of HVDC: AC compared DC - CUSP· PDF fileHVDC is particularly suited to undersea transmission, where the losses from AC cables are large. –First commercial HVDC link (Gotland 1 Sweden, in 1954) was an undersea one. Back-to-back converters are used to connect two AC systems with different frequencies –as in Japan –or two regions where AC is not synchronized –as in the US.
