Design and Analysis of a Multilevel Converter for Micro Distributed Generation System

In this paper, design and analysis of a multilevel converter for micro distributed generation (DG) system is presented. The design of the multilevel converter is simulated using Matlab Simulink. The power converter is designed to accept low input voltage from micro renewable energy sources such as a single solar panel or a low power wind turbine. The power converter produces an output voltage of 230V and frequency of 50Hz. Its basic principle of operation including performance analysis are presented. The system is suitable for use in micro DG system either on-grid or off-grid applications.
