Direct drive axial type wind energy conversion system with Z source inverter and modified space vector modulation

The demand of energy is increasing day by day and the fossil fuels are moving towards the end. There comes the portance of non-ending sources like wind energy. The proposed system is a wind energy conversion system consisting of Z source inverter(ZSI). Z source inverter is the one which can invert DC and buck boost operation is also possible. It carries more advantages than conventional buck boost converter. The existing system consists of a three stage power conversion having rectifier, boost converter and inverter. In the proposed system boost converter and inverter is replaced by Z source inverter so that the efficiency is increased. The proposed system is modelled as equation models. The space vector modulation is also used to improve the performance of inverter.
