Photovoltaic power generation systems have good development prospects,but their voltage output is easily affected by environmental factors,making it difficult to ensure sustained and stable output.Therefore,this article designs a photovoltaic charging controller connected to the load,and dynamically adjusts the load impedance according to the stable maximum output power under various working conditions to optimize the utilization of solar energy.To optimize and solve this problem,a photovoltaic charging controller design based on ARM control chip was completed by charging and discharging characteristics of the photovoltaic controller.
