The stability of power converters with a filter front-end is a well-known problem that can be more challenging considering a long input cable. Such long cable potentially worsens the performance of the system and introduces instability when connected to a constant power load (CPL). This paper proposes a hybrid stabilization technique that combines physical and virtual damping methods. Moreover, the solution will minimize the capacitance requirements in scenarios where long input cables are involved. Additionally, the parallel damping converter will be studied as an alternative approach for stability improvement. Damping solutions are simulated and experimentally validated on a dual active bridge (DAB) converter connected to a long input cable.
