Abstract
An improved MPPT (Maximum Power Point Tracking) algorithm charge controller exploiting an interleaved synchronous buck converter has been designed and realized to extract the maximum power from a photovoltaic panel. The converter sends the available photovoltaic energy to a battery pack thanks to an input control loop that reads the input voltage and limits the output current of the converter, thus fixing the photovoltaic panel voltage to its maximum power value. The MPPT is achieved through a microcontroller based PAO (Perturb And Observe) algorithm. The converter is capable of driving two separate battery packs thanks to two onboard solid-state switches, thus allowing a longer life cycle and a better energy management.
利用交错同步降压变换器，设计并实现了一种改进的最大功率点跟踪(MPPT)算法电荷控制器，以提取光伏板的最大功率。转换器通过输入控制回路读取输入电压并限制转换器的输出电流，将可用的光伏能量发送到电池组，从而将光伏板电压固定在其最大功率值。MPPT通过基于微控制器的PAO (Perturb And Observe)算法实现。由于两个板载固态开关，转换器能够驱动两个独立的电池组，从而允许更长的生命周期和更好的能源管理。
