Abstract—This paper presents a performance characteristics and harmonic analysis of self –excited induction generator (SEIG) fed current source inverter for isolated wind energy conversion system. The induction generator, solid state power electronic converter devices and inductor filter components are modeled by using MAT LAB / SIMULINK. In the growing applications and environmental conditions, various types of technologies are introduced to delivering the quality of power to the grid. The main objective of the paper is to track and extract maximum power to the grid connected wind energy conversion system. The current source inverters are used to achieve boost operation with the help of series inductor. The variable voltage, variable frequency supply at the generator terminals is rectified and inverted using power electronic converters. The modulation index of the proposed inverter is adjusted, and to obtained the maximum output power. The experimental results of the SEIG output are compared with the simulation results.
