The Design of Charging Controller in Wind-Photovoltaic Hybrid Power Generation System

Abstract—With the energy crisis and environmental degradation increasing, people are increasingly concerned about the development of environmental protection and new energy technologies. According to the output characteristics of solar photovoltaic batteries, this paper is designed to take a DC chopper as the main circuit of a photovoltaic battery, and on this basis, this paper studies control methods suitable for PV charging; according to the characteristic that the small wind power generation has a high requirement with the wind power generation, researchers use the lifting pressure circuit as the main circuit of a wind energy charger. Finally, this paper makes the software design for PV charging controllers and wind charging controllers.
