System-Level Black-Box Dc-to-Dc Converter Models

Abstract

This paper presents the application of black-box terminal characterization models (BBTC) for the simulation and analysis of distributed power electronics systems composed by commercial power electronics converters and filter modules. The models are shown to effectively predict the transient and steady state response of interconnected distributed power systems. They are also used to predict the small-signal stability between source and load converters. All simulation results are validated with experimental data.
