摘　　要：文中通过对比风光互补系统各种常用最大功率点跟踪(MPPT)控制策略,提出了改进的MPPT控制策略。光伏电池阵列输出功率通过电压反馈扰动MPPT控制策略进行控制,风力发电机输出的功率采用变步长扰动MPPT控制策略;在蓄电池支路上串联一个MOSFET管,起到截止充电功能,并提出了改进的三段式充电方法。By comparing all sorts of commonly used maximum power point tracking（MPPT）control strategy for PV array and wind turbine hybrid system,this paper proposes some improved MPPT control strategies.The output power of PV is controlled with MPPT control strategy using voltage feedback disturbance,and the output power of the wind generator is regulated with MPPT control strategy utilizing the variable step size perturbation.A MOSFET is added in series with the battery branch to switch the on-off state of the charge loop.Then an improved three-step charge method is introduced.
