HVDC (High Voltage Direct Current) Transmission System: A Review Paper [PDF]
Gyancity Journal of Engineering and Technology, 2018 Back in the early days of electricity supply, AC (alternating current) was adopted for power transmission because it could be stepped up or down as needed by transformers and because it could be interrupted more easily than DC (direct current). High-voltage AC grids evolved as an efficient way to connect existing islands of distribution grids and large
