Design, Simulation and Implementation of a 300W 24V Power Converters for Magnetic Levitation Vertical Axis Wind Turbine System

摘要

This paper presents a 300W AC/DC/AC power converter for wind energy system. Magnetic Levitation Vertical Axis Wind Turbine is used to harness energy at low wind speed of less than 3 m/s which is suitable for residential area in Malaysia. Three phase voltage produces by wind turbine is rectified using three phase rectifier. A boost converter is employed to convert the rectified DC voltage to a higher level. The output stage consists of full bridge circuit that produces a sinusoidal AC voltage using SPWM switching technique for common AC loads. When operating in rated condition, this system reduces 300W of energy consumption from utility.
