Stability analysis, discrete time modeling and active stabilization of DC-DC converter, taking into account the load dynamics

Abstract

For stability analysis, it is often chosen to model power loads by constant power loads (CPL). However, this model may be too strict, as it is the worst case scenario. In this paper, it is intended to change the model of a power load to increase the calculated stability zone of a DC system composed of a source converter, an LC filter and the power load. A stabilization term is included in the command of the source in order to increase the power range. The simulation and experimental results that are given to validate the proposed model and to demonstrate the effectiveness of the proposed stabilizer and its tuning.
