摘　　要：针对导纳增量法在低光照情况下不易进行最大功率跟踪的缺点,结合线性比例电流法提出了一种线性比例电流法结合导纳增量法的控制策略。利用Matlab/Simulink仿真软件,构建了光伏电池板和线性比例电流法结合导纳增量法的最大功率跟踪控制的仿真模型。仿真结果验证了线性比例电流法结合导纳增量法的合理性和有效性。linearly proportional to the currencombined with incremental conductance control strategy fothe faulof incremental conductance in low lighsituationiproposed.
