摘要
在此提出一种非隔离光伏控制器最大功率点跟踪(MPPT)控制策略,采用脉冲频率调制(PFM)与脉宽调制(PWM)混合调节模式来实现光伏组件输入功率快速靠近最大功率点(MPP),且在MPP附近实现输入电压的精细化调节,从而提高光伏组件的发电效率。方法简单易于实现数字化,实验结果验证了该控制策略的有效性。
A control strategy of maximum power point tracking(MPPT)for non-isolated photovoltaic controller,which adopts pulse frequency modulation(PFM)and pulse width modulation(PWM)mixed modulation control mode to realize the input power of the photovoltaic module close to the maximum power point(MPP)quickly,and realize the fine regulation of input voltage near the MPP,so as to improve the generation efficiency of photovoltaic modules.The method is simple and easy to implement digitally.The experimental results verify the effectiveness of control strategy.
