Photovoltaic Temperature Difference Combined Power Generation System Using Double Input DC-DC Converter

As people's awareness of environmental protection is becoming stronger and stronger,and traditional energy on the earth is also gradually lacking,people are gradually paying more attention to the development and utilization of new energy.Among them,solar energy is the most popular because of its wide application range and relatively stable advantages.People like it,but the solar panel is cracked due to the high temperature of the panel surface during use.Therefore,in this paper,photovoltaic power generation and thermoelectric power generation are combined,and part of the thermal energy of the solar panel is used for thermoelectric power generation to better achieve the energy cascade use.This article decides to combine them to generate electricity to compensate for their own shortcomings based on the problems that people have in the use of solar panels and the respective advantages and disadvantages of solar panels and thermoelectric cells.This photovoltaic temperature difference combined power generation system is designed,and then the electrical energy they emit is transformed through a dual-input DC-DC converter specifically designed for this generation system in this article,and finally the converted electrical energy is used to charge the cell.It can provide electrical energy for small power equipment such as the sensing system or monitoring system of agricultural greenhouses.This system combines the two with the cell energy storage system after analyzing the characteristics of the photovoltaic cell and the temperature difference cell,and selects and calculates the topology of the dual-input DC-DC converter used by the system through various system parameters.Various hardware parameters are used to design the system software.The output terminal uses a constant current and constant voltage method to charge the cell,and monitors the system through real-time feedback of voltage and current values to ensure that the system operates normally.The system not only combines two new energy sources for power generation,but also reduces pollution to the environment,and also reduces the cost of electricity.The construction of the system is also more convenient and suitable for use in a variety of environments,which also greatly reduces the cost of transmission equipment construction.In addition,in theoretical research,this system has also broadened the research direction of photovoltaic power generation,and laid the foundation for the research on the comprehensive utilization of a variety of new energy sources.In the engineering practice,the use of photovoltaic power generation and thermoelectric power generation is more in line with the future development direction of the energy industry,and has a positive significance in the development of modern agriculture to smart agriculture.
