The Condition Number Perspective in Modeling and Designing an Electronic IDBIC Converter

This paper proposes a novel method of evaluating the Independent Double-Boost Interleaved Converter’s performance, which can offer an overview of its behavior and can enhance the design stage of the converter. The concept of “condition number” is utilized and applied to the converter’s model. Correlations between the condition number variation and the converter parameters lead to a qualitative assessment of the converter’s behavior and offer the possibility to anticipate aspects like the stability and response of the converter. An in-depth analysis is conducted, starting from the state matrix and continuing with a series of presumptions regarding the converter and its operating mode, obtaining a series of expressions that define the condition number for the converter.
