Abstract

This paper presents a simple STATCOM scheme using a cascaded two-level inverter-based multilevel inverter. The proposed topologies have two VSI based two-level inverters are connected in cascade through open-end windings of a three-phase transformer and filter elements. Converter fed dc-link voltages are regulates at different levels to obtain four-level operation. The proposed STATCOM multilevel inverter has operates under MATLAB/SIMULINK environment and the results are verified in balanced and unbalanced conditions. Further, stability behavior of the topology is investigated. The system behaviors are analyzing under various operating conditions using fuzzy logic control
