| Abstract |
Basic concepts with respect to stable operation of semi-autonomous low-voltage DC-grids are discussed.Design considerations on the output impedances of power electronic converters are analysed in order to avoid resonance issues within a DC-grid. With calculated or measured converter output impedances,potential resonance problems due to background harmonics between aggregated power modules and theDC-grid can be forecasted. Simulation results are included for verification of the proposed ideas. |
