This paper presents a new passivity-based control strategy using interconnection and damping assignment for a three-phase quasi-impedance source inverter connected to the grid through an inductive filter. The designed controller regulates the DC bus voltage to the required value while simultaneously regulating the active and reactive power injected into the electrical grid. As a nonlinear stabilizing control technique, it achieves good dynamic performance and ensures system stability in response to changes in the reference voltage and in the power injected into the grid. Simulation results are presented to validate the performance of the proposed control strategy.

摘要

This paper presents a new passivity-based control strategy using interconnection and damping assignment for a three-phase quasi-impedance source inverter connected to the grid through an inductive filter. The designed controller regulates the DC bus voltage to the required value while simultaneously regulating the active and reactive power injected into the electrical grid. As a nonlinear stabilizing control technique, it achieves good dynamic performance and ensures system stability in response to changes in the reference voltage and in the power injected into the grid. Simulation results are presented to validate the performance of the proposed control strategy.
