Photovoltaic Intelligent Integrated Power Supply
A photovoltaic thermoelectric hybrid (PV-TEH) system with intelligent power supply management is proposed in this paper. Combining the advantages of the thermoelectric generator (TEG) and the thermoelectric cooler (TEC), the. A photovoltaic thermoelectric hybrid (PV-TEH) system with intelligent power supply management is proposed in this paper. Combining the advantages of the thermoelectric generator (TEG) and the thermoelectric cooler (TEC), the TE intelligent switching circuit and the water speed regulation circuit are presented in this system. Due to the energy harvesting of the TE devices, the high conversion efficiency can be realized in the PV-TEG mode. The experimental results show that the output power of the PV cell in our work is increased by 14.4% on average compared with that in a PV system without TE. Since the proposed system overcomes the disadvantage of power consumption for TEC throughout the whole process, the electrical energy generated by the TEG is effectively harvested, achieving 57.9% im.
