The Applied Research of the Super Capacitor in the Maximum Power Tracking of Photovoltaic Systems

Article Preview

Abstract:

Through analyzing the working principle of the technology of maximum power point tracking in the photovoltaic system, the maximum power tracking circuit is designed. In the hybrid energy storage devices of the super capacitor and battery, the super capacitor is a secondary storage device. Through photovoltaic controller is connected with the photovoltaic cells, photovoltaic cells can achieve the status of the maximum power point tracking. Through the bi-directional DC-DC converting circuit connecting with the battery, the battery can effectively decrease the times of the charging and discharging and works stably. It improves the working efficiency and life of the system.
