A Generalized Port-Hamiltonian Approach to Modeling Losses in DC-DC Converters

https://doi.org/10.58571/CNCA.AMCA.2025.060

Resumen: This paper presents a systematic methodology to model conduction losses of passive and active elements of power converters within the Port Controlled Hamiltonian (PCH) framework. The motivation behind this approach is not only to achieve a more realistic system representation, preserving the Hamiltonian structure, but also to enable the development and analysis of control schemes that optimize transient performance. The Port-Hamiltonian models for the two basic DC-DC converter topologies, Buck and Boost, are unified into a generalized structure. Finally, the proposed model is validated numerically through MATLAB®-Simulink® simulation comparing the ideal model, the proposed PCH model, with a reference in a Simscape implementation.
