In order to alleviate the fossil energy crisis and optimize the photovoltaic grid connected technology,the experimental single-phase photovoltaic grid connected inverter is designed and implemented. The STM32F103C8T6 is used as the microcontroller and the H6 bridge topology is used as the main circuit of inverter. According to the experimental structure of single-phase grid connected PV inverter, respectively on the internal module, circuit control system, detection system for the research, design and production of inverter;under laboratory conditions repeatedly tested and analyzed the effect of a series of factors on the efficiency of the grid. The simulation results of MATLAB and experimental data show that the inverter can improve the dynamic response speed of the system and reduce the harmonic content of the grid connected current.
