The Study in Photovoltaic Control System Based on FPGA

This paper provides a small power photovoltaic control system based on FPGA. And a new way is applied to trace the maximum power point based on the improved accelerating simplex method. The system perfects the management and protection for the charge and discharge of storage battery also for the load and solar power supply. It´s very important part that the techniques of maximum power point tracking and islanding protecting, but also the technique for inverter to connected with grid are discussed at emphasis. Test show that the system can be made use of in several photovoltaic products and obtain the satisfied result.
