Abstract:This paper mainly researches on the interleaved boost circuit of the high power direct drive wind power system. On the base of carrier wave phase-shifted technology,a new control method which treats each branch as a separate circuit is proposed. This method can not only keep the output voltage constant,but also realize the current sharing between each branch. The simulation and experiment results verify the availability of the proposed method. And it can be applied in wind power system.
Keywords:direct drive  interleaved Boost  DC voltage  inductance current  current sharing
