摘　　要：设计了能实现跟踪太阳能最大功率点（MPPT），并对蓄电池充放电进行管理的数字化智能光伏控制器。MPPT的硬件由反激式开关电源实现，使得光伏发电系统的效率最高。开关电源电路同时提供蓄电池充电管理。控制器的控制核心是PIC16单片机，MCU的应用使得硬件电路简单、可靠，便于控制器的调试和升级。此外还设计了蓄电池反接保护、过载保护电路。实验结果表明，该控制器工作稳定可靠，满足系统要求的技术参数。A digital and intelligent PV controller that can realize following the track of maximum power point（MPPT） and management of battery＇s charging and discharging. Hardware of MPPT is mainly composed of switching power supply. The MPPT function makes system is most efficient. Furthermore, MPPT circuit also implements the management of the battery. The core of this controller is an PIC MUC, which simplifies hardware architecture, makes system more stable and easier to be debugged and updated. What＇s more, some protection circuits are also adopted such as reverse connection of battery protection and overload protection circuits. Experimental result indicates this controller works stably and properly.
