abstract

• This note focuses on the analytical design of a proportional-integral controller based on the passivity approach for a high-gain transformerless DC-DC converter. The modeling stage relies upon energy considerations, and the dynamical behavior is derived employing the Hamiltonian formalism. Moreover, the overall control strategy is designed in the vein of PI-PBC to achieve precise output voltage regulation. Furthermore, an immersion and invariance estimation scheme is proposed to induce adaptive properties to the closed-loop system due to an unknown (but constant) resistance load. Several simulation scenarios were also tested using MATLAB/SIMULINK to validate this proposal exhibiting proper current tracking, precise voltage regulation, and robust behavior. Finally, a discussion of results and some outlooks end the contribution. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
