High-Voltage dc Conversion: Boosting Transmission Capacity in the Grid

The electric grid is undergoing a technological transformation due to advances in a number of fields, including power electronics, photovoltaic cells, wind turbines, telecommunications, and many others. An increase in environmental awareness and the need to meet emission targets implemented throughout the world further drive grid evolution. These social and technological changes are leading to a transition in the composition of the power supply, with a reduction in the number of large conventional thermal and nuclear plants and a proliferation of solar and wind generation.
