Energy Conversion and Economics, Volume 5, Issue 3, Page 167-178, June 2024.Abstract The DC multi‐port converter's applications are increasing owing to its favourable features, including variable control mode, high power density, and bi‐directional power supply. On the other hand, the impedance interaction between each port of the electrolytic capacitor‐less DC multi‐port converter may generate an instability.
