Passivity-based Stabilization of DC-DC converters with Constant Power Loads

Abstract

In this paper, we propose a new mathematical framework that allows combining power converter models with impedance based models, this is performed by using high order terms. We also introduce a passivity analysis for power electronics converters with stability problems due to the connection of constant power loads. Finally, we introduce a solution of instability problems by designing lossless stabilizing filters using the concept of passivity. The paper includes both analytical and experimental results that corroborate the main theoretical achievements of the proposition.
