摘　　要：以自适应占空比干扰观测MPPT算法为研究对象,探明自适应占空比干扰观测MPPT算法对太阳能独立光伏系统转换效率的影响程度,优化出最佳算法模型。在日照强度、环境温度等系统参数扰动的情况下,该算法能够保持系统稳定以及良好的动态特性,最大限度地提高太阳能电池转换效率,为实现光伏系统效率最优化提供理论指导和技术支撑。This paper studied the influence degree of the adaptive disturbance observation MPPT algorithm on the conversion efficiency for PV system and optimized the best model of the algorithm. Under the parameter perturbation such as sunshine intensity and environmental temperature, the algorithm can keep the system stable and good dynamic charac- teristics and improve solar cell conversion efficiency. It provides theoretical guidance and technical support for the reali- zation of the PV system efficiency optimization.
