Resumen:

This paper analyzes the stability of a PI controller for the input voltage regulation of a three-phase two-level inverter within a PV application. The stability analysis is carried out through the Hermite-Biehler criterion, which is used in the parameterization of a robust region in which the system is stable. The stability region gives all the proportional and integral gains of the PI controller that stabilize the linearized closed-loop system. Simulation results show that the system is stable under power changes in the PV array. © 2021 IEEE.
