Design and implementation of power converters for wind energy conversion system

This paper presents the design and implementation of power converters for wind conversion systems. The power converter can not only transfer the power from a wind generator, but also improve the stability and safety of the system. The proposed system consists of a permanent magnet synchronous generator (PMSG), a DC/DC boost converter, a bi-directional DC/DC converter and a full-bridge DC/AC inverter. The wind generator is the main power source of the system, and the battery is used for energy storage and power compensation to recover the natural irregularity of the wind power. In order to keep producing to the maximum power output from the wind power generator, a digital signal processor (TMS320LF2407A) is used to realize the system controller. Finally, a 200W wind energy conversion system is built and experimental results are provided to verify the theoretical analysis and feasibility of a wind power generator system.
