Improved Output Voltage in Micro Wind Power Generator Fed Z Source Inverter Based System

Abstract

The micro wind power generation system is used to generate the power at low cost. In this paper, generator fed SEPIC, Z source inverter based systems are presented. The unique feature of Z source inverter is shoot-through duty cycle control by which any desired output voltage even greater than input line voltage is possible. Both buck-boost capabilities in single stage conversion are possible. This is not possible in conventional inverters. Also conversion losses are reduced in Z-source inverter due to single stage conversion which increases the output voltage of the system. Keywords: micro-wind power generation system, Single-Ended Primary Inductor converter, Z source inverter.
