摘　　要：本文介绍了采用双BUCK电路的太阳能光伏发电控制器设计。两路BUCK电路并联,通过交错输出给蓄电池充电,降低了输出纹波、提高了系统可靠性,降低了温升。采用改进的恒定电压法和变步长扰动算法相结合的MPPT控制策略,调节PWM占空比输出使光伏阵列实时获得最大功率输出,实验表明该控制器提高了太阳能转换效率。This paper introduces the design of solar photovoltaic power generation controller with dual BUCK circuit？ Dual BUCK circuits are connected in parallel, charging the battery through interleaving output, which reduces output ripple, improves system reliability and reduces temperature rise？ The MPPT control strategy which combines the improved constant voltage method and variable step length disturbance algorithm is used to adjust the PWM duty ratio output to get the maximum power output of the photovoltaic array in real time？ The experiment shows that the controller improves the efficiency of solar energy conversion？

关 键 词：双BUCK 恒定电压算法 变步长扰动算法
