Abstract

The present paper addresses the challenge of sinusoidal current injection into single-phase microgrid loads by controlling a pulse-width modulated current-source converter (PWM-CSC). The proposed control strategy is based on the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) framework, which exploits the system’s passivity properties to design a controller that ensures global stability while shaping the closed-loop energy function. The converter is modeled using a port-Hamiltonian formulation, enabling the systematic development of the IDA-PBC scheme. This approach effectively transforms the trajectory tracking problem into a regulation problem, ensuring asymptotic stability and guaranteeing a wellposed energy function in the closed-loop system. Numerical simulations validate the proposed strategy, demonstrating that the sinusoidal current supplied by the PWM-CSC maintains a tracking error below \( 2 \% \) and harmonic distortion levels below \( 3.5 \% \) for both voltage and current waveforms. All simulations were performed in MATLAB/Simulink using the SimPowerSystems toolbox, version 2024b.
