摘要
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.
