| Abstract |
The transmission and distribution of electrical energy with direct current (dc) is a promising alternativeto established alternating-current (ac) systems. Higher efficiencies, fewer lossy pulse-width modulatedconverters and smaller transformers reduce operation and investment costs. Moreover, dc collector gridswithin wind parks leads to benefits for harvesting electrical energy. In this paper, a modular dual-activebridge (DAB) dc-dc converter system for integrating renewable energy sources, especially wind turbines(WT), into medium-voltage dc (MVDC) grids is presented and analyzed. Also, the design and efficiencyof the machine-side power converter of the WT for dc grids are discussed. |
