  "textContent": "A converter for electrical connection to a three-phase electrical grid and a single-phase electrical grid is provided. The converter includes three DAB modules, each for converting a respective alternating current of a three-phase electrical grid. When connected to a single-phase electrical grid, the third DAB module is bi-directional such that it is operable to filter the power output of the first and second DAB modules. The converter further includes a filter capacitor in electrical communication with the third DAB module through a relay, wherein the relay is responsive to a controller to couple the third DAB module to the filter capacitor when the single-phase electrical grid is detected and to couple the third DAB module to a grid rectifier when the three-phase electrical grid is detected.",
