基于Boost变换器的最大功率点跟踪判据及实现算法
Maximum power point track criterion and implementation algorithm based on boost converter
摘要
Abstract
The principle of Maximum Power Poine Tracking(MPPT) control system is analyzed based on boost converter with only the port voltage of sample solar cell.The criterion to reach the maximum power point is deduced.It is pointed out that MPPT system reaches maximum power point when the ratio of the variation of on-time to off-time of the switch is equal to the relative change rate of the solar cell port voltage.According to the output characteristic curve of the solar cell and the obtained criterion,the principle to adjust the change direction and step variation of the duty cycle is concluded.On this basis,a novel control strategy and algorithm realizing MPPT is proposed.The feasibility of the proposed control strategy and criterion is verified by the experimental results.关键词
