Abstract Voltage oscillation may be caused by impedance mismatch after cascading the high-capacity power electronic converters in the low-voltage power transformation and distribution subsystem of the ship. In order to explore the factors that affect static stability of the cascaded system with high-capacity DC-DC converter, this paper mainly focused on modeling and analyzing of output impedance. Firstly, the small signal model of the high-capacity DC-DC converter was established, and correspondingly, the output impedance models was derived. Secondly, the system stability according to the impedance ratio criterion was analyzed. It is clear that the peak value of the output impedance of the high-capacity DC-DC converter is the dominant factor causing the impedance mismatch. Thirdly, by exploring the influence of the control strategy, control parameters and filter parameters on the converter’s output impedance amplitude under different operation modes, the parameter optimization direction was found for improving the static stability of the system. Finally, the theoretical analysis was verified by PSCAD/EMTDC simulation and test.

Key words： DC-DC converter output impedance cascaded system static stability
