In order to reduce the current of each IGBT and reduce the harmonic current into the grid, a multiple AC-DC-AC full-scale converter which is suitable for high power direct drive wind power generation systems is adopted. The reasons of DC-link voltage fluctuation of the grid connected converter are analyzed. An improved DC-link voltage control method for multiple grid connected converter in direct drive wind power generation systems is proposed in this paper to limit the fluctuation range of the DC-link voltage. The instantaneous generator power and grid voltage feedbacks are used to improve the dynamic response of the DC-link voltage. Simulation and experimental results verify the analysis and the conclusion.
