Abstract

This paper proposes a rigorous modeling and control strategy based on the port-Hamiltonian (\( \mathbf{p H} \)) framework applied to a bidirectional DC-DC extended SEPIC converter intended for Vehicle-to-Everything (V2X) applications. Unlike commonly used idealized averaged models, the proposed formulation explicitly incorporates dissipative effects arising from parasitic resistances of inductors, equivalent series resistances of capacitors, and switching component losses. The system is described using canonical energy variables, ensuring intrinsic consistency of power exchanges and dissipation. A Lyapunov based stability analysis is carried out, and an Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) law is developed to guaranty output voltage regulation under bidirectional power flow operation. The desired equilibrium point is analytically computed from the dissipative steady-state equations, avoiding the use of iterative numerical methods. MATLAB/Simulink simulation results confirm the theoretical validity of the proposed approach and demonstrate robust regulation under load variations.
