An Efficient Upf Rectifier For A Standalone Wind Energy Conversion System

Abstract

This paper use a suitable power converter topology and design a suitable controller for a Wind Energy Conversion system with Permanent Magnet Synchronous Generator (PMSG) for stand alone and grid integrated operations. The present work presents the system in which a PMSG feeds an isolated load through a closed loop boost converter. The output voltage and frequency of the PMSG is variable in nature due to non uniform wind velocities and is not synchronized with the grid frequency. In order to condition and feed it to grid we need power electronic interface. The variable ac output is rectified by a diode rectifier and maintained constant by a boost converter. The boost converter is provided with a closed loop feedback control, which is designed using PI controller.
