基于STM32的高效光伏能量转换系统设计
Design of high-efficient photovoltaic energy conversion system based on STM32
摘要
Abstract
A photovoltaic system used for microsensor equipment power supplying on the island was designed,which takes STM32 as the main controller. The dual⁃axis tracking platform was designed to realize the sun tracking. The new placement scheme of light sensor is studied,in which the angle sensor SCA100T⁃D02 is added to measure the azimuth angle and elevating angle of the solar panel. The angle sensor is compared with GPS module by the controller to perform the location auxiliary cali⁃bration and form the close⁃loop control. The main controller based on MPPT algorithm uses PWM control method for lithium bat⁃tery charging. The experimental results show that the system can track the sun accurately,improve the efficiency of photovoltaic conversion greatly,and has broad application value and prospect.关键词
