Design And Implementation Of Photovoltaic Power Generation System Based On TMS320F28035

In the current environment in which China strongly advocates environmental protection and energy is in short supply on a global scale,green renewable resources have become the first choice for people to produce and live.Photovoltaic power generation has become the best choice because of its clean,pollution-free and sustainable advantages.In the photovoltaic power generation system,improving the photoelectric conversion efficiency and enhancing the system stability is a key issue in the study.To solve the above problems,a photovoltaic grid-connected power generation system based on TMS320F28035 was designed.Based on the research of photovoltaic array principle,this paper conducts a comprehensive theoretical analysis of the photovoltaic grid-connected system.In terms of hardware circuit,the design of the pre-boost boost circuit,the rear-stage full-bridge inverter circuit,the same-frequency in-phase circuit,etc.Parameter selection,in terms of control algorithms,analysis and design of SPWM algorithm,maximum power point tracking algorithm,TMS320F28035 as control chip,CCS5.0 software,control program writing and debugging.Finally,under the support of the above-mentioned theory,the hardware circuit was made and debugged.Based on the relevant performance indicators,the oscilloscope was used to collect the relevant experimental data,the quantitative analysis of the data results,and the rationality of designing the photovoltaic grid-connected power generation system was elaborated.
