Abstract
In order to realize the maximum conversion efficiency of photovoltaic cells, the solar energy output current should follow the instructions current benchmark periodically and automatically, namely, the limited ring cycle of maximum power point tracking control (limited cycle ring MPPT control) technology was used to achieve the maximum output power. The technical principle, design methods and practical test results of circuit were introduced in this paper. The practice shows that the charger with simple circuit has high control accuracy, high charging efficiency and excellent practicability. The main feature of the charger is to harvest the energy of photovoltaic cells completely in different light conditions. In addition, the circuit can act as a large-capacity DC system of individual energy supply source.关键词
