摘　　要：该文针对风力发电系统提出了一种新的MPPT策略——基于Boost变换器来实现直驱式永磁同步风力发电系统(PMSG)的最大功率跟踪。文中详细分析了风力机功率曲线与Boost变换器占空比之间的关系,提出了占空比控制的MPPT控制方法。理论分析及其仿真结果表明该方法的正确性与有效性。In order to utilize wind energy maximumly,the control technologies of maximum power point tracking（MPPT）has already been a research hotspot.A novel MPPT strategy in wind generator system was presented in this paper.The design of a Boost converter circuit used to achieve the maximum power control of wind turbine driven permanent magnet synchronous generator（PMSG）.The relationship between power curve of wind turbine and duty-cycle values of Boost converter were analyzed in this paper,then the duty-cycle MPPT control method was presented.At last,theory analysis and simulation verified the correctness and validity of the strategy.
