| Abstract: |
| As the direct battery-charging by photovoltaic array has low efficiency，a control scheme of maximum charging based on real-time system parameter tracking is proposed. A microprocessor-based intelligent CC（Charging Controller） with switching parallel Buck／Boost topology is developed，which carries out the maximum gathering of solar energy. Practical operation shows that，it describes dynamically the system parameter information and enhances the electric charge collection efficiency. The system dynamic tracking time is about 4 ms and the electric charge collection efficiency increases more than 20 %. The CC with microcontroller reduces the cost of photovoltaic system by avoiding over power configuration of photovoltaic array. |
