Dynamic analysis of an on-board DC distribution system with active stabilizer

Abstract : Stability of onboard dc power systems is influenced by nonlinear behavior of converter-controlled loads with constant power characteristics. This nonlinear dynamics, in line with reduced size input filters used in transportation systems, has a degradation effect on the dynamic performance and stability of the system. This paper addresses stability study of a dc power system with an active stabilization system. Different load power dynamics are implemented to demonstrate the impacts of slow and fast load dynamics on the stability of the system. Performance of the stabilizer, in steady state and transient, is also investigated through a series of experimental tests.
