| Abstract |
In DC grids, DC circuit breakers (CB) are used to interrupt currents in case of a fault and to dissipate the remaining energy in the line. Independent of the actually DC CB concept, different energy dissipation concepts can be used, which also influence the performance of the DC CB. In this paper, the energy dissipation with different circuit arrangements, where the energy is dissipated in a single loop, in two loops or in two coupled loops, are discussed and compared. Additionally, the effect of different voltage waveforms across the DC CB and the distribution of the current limiting inductance on the input and the output side of the DC CB are investigated. |
