N2 - The DC distributed power systems (DPS) have attained much attention because of its characteristics of high efficiency, high power density and flexible configuration. However, interactions between converters may cause stability issues. Currently, research mainly focuses on the DPS with a DC voltage bus, including the stability analysis and the approaches to improve the system stability. This paper is to establish stability criteria for DPS with a DC current bus. Firstly, basic current type DC/DC converters and their small signal models are introduced. Then, the current bus DPS is derived, discussed, and the stability criteria is obtained by using two-port small signal model. The proposed criteria is verified by comparing theoretical calculations and simulations of a DC current bus DPS. Finally, an experimental prototype is built to validate the theoretical analysis and simulations.
