In Multi-converter power electronic systems, load converters exhibit constant power load (CPL) behavior for the feeder converters and tend to destabilize the system. In this paper, Buck DC-DC converters are taken as an example, and the implementation of active-damping techniques has been shown to analyze the stability of multi-converter power electronic systems. Moreover, active damping is generally implemented by a feedback loop, which produces the effect of a virtual resistor and damps the oscillations, the proposed active-damping method can overcome the negative impedance instability problem caused by the CPLs. The effectiveness of the proposed approach has been verified by Matlab/Simulink simulations.
