State Separate Modular Modeling Methodology of Multioutput DC-DC Converters

Conventional modeling and simulation of $n$ -output dc-dc converters requires $(n+1) \times (n+1)$ matrix computations. This approach increases the modeling approach's complexity and increases the design and simulation time required for the modeling process. A state separate modeling methodology is proposed where each state of the dc-dc converter is considered separately and combined with the help of a multiplexer. The proposed modeling approach is modular and thus improves the scalability to multiple outputs. The proposed methodology aids the designer in designing and modeling multioutput dc-dc converters faster, enabling fast prototyping. The proposed model outperforms the existing mathematical models in terms of computation time. The output voltage variation to duty cycles has a root mean square error in between 0.08 and 0.22 V.
