Abstract Cascaded structure is a typical structure in a DC distributed power system. However, the interaction between its individually designed power modules/subsystems may cause the instability problem of the whole system. This paper first analyzes its instability reason, then, proposes the adaptive active capacitor converter for improving the stability of cascaded dc power supply system. The converter’s physical meaning, operation principle and detail design are discussed. Finally, the solutions are verified by experiment on a 120W instability Buck type cascaded system.

Key words： Cascaded system stability adaptive active capacitor converter
