High Voltage Direct Current (HVDC) transmission transmits bulk electrical power over long distances using direct current instead of alternating current.
It offers lower losses and better control for long-distance and underwater power transfer.
At the sending end, a rectifier converts AC to DC; the power is transmitted as DC; and at the receiving end an inverter converts it back to AC. Modern systems use line-commutated or voltage-source converters.
HVDC has no reactive power losses, allows interconnection of asynchronous grids, and is ideal for submarine cables and very long overhead lines.
