| 摘 要： | 为了提高光伏系统的效率,需对光伏阵列进行最大功率点的跟踪控制.根据太阳能光伏阵列的输出特性,在传统微扰观察法的基础上采用了一种新的变步长的改进算法进行最大功率点跟踪,克服了定步长跟踪的弊端.利用AVR单片机设计了一台具有最大功率点跟踪功能的光伏发电电源系统,并对其进行了仿真.结果表明,该改进算法能够有效提高系统对光伏阵列的最大功率点跟踪的效率,说明该系统具有一定的实用性.

| Abstract: | In order to improve the efficiency of the photovoltaic system, the photovoltaic array must make a tracking control for maximum power. According to the output characteristics of the photovoltaie array, based on the traditional perturbation observation method, a new variable step size algorithm is applied to overcome the defects of fixed step tracking. Through using the AVR microcontroller, the photo- voltaic power supply system with maximum power point tracking function is designed and simulated. The results show that the improved algorithm can effectively improve the system MPPT （Maximum Power Point Tracking System） efficiency of photovohaie array. So, the system has a certain practicality. |
