Abstract
In this paper, stability analysis of a typical DC/DC Boost converter feeding a Constant Power Load (CPL) with and without a Battery Energy Storage (BES) is discussed and explained. CPLs, usually, cause instability issues for DC/DC converters due to their negative impedance characteristic. The state-space averaged model analysis of the converter is performed and stability regions of the converter while feeding CPL and constant voltage load (CVL) are investigated. A dual-loop control method is utilized to stabilize the power electronic converter while providing constant power and regulating the output voltage to satisfy both CPL and CVL. Simulation in Matlab/Simulink environment is performed to verify the proposed control method.
