Performance improvement usig three-level neutral point clamped statcom performances using robust controllers

This paper deals with multilevel Neutral Point Clamped (NPC) inverter applied as STATCOM. The proposed control with Space Vector Modulation (SVPWM) switching and decoupled current control with (IP) controllers have been tested to prove the advantages of the proposed control. In order to ensure fast and stable voltage regulation, reduced switching Losses and minimizing harmonic voltage under all operating conditions, we focused in this study on design and implantation of sliding mode controller for Statcom. The simulation has shown the improved performance of the proposed controller with effectiveness and efficiency results compared with the conventional IP controller.
