DESIGN OF CONTROL SYSTEM FOR PHOTOVOLTAIC INVERTER BASED ON DSP

Energy crisis and environmental pollution has become increasingly serious in China, the new energy development and use and up to the world agenda. Solar as a new clean energy, with its clean, easy access to the advantages of being the world's attention. Solar photovoltaic power generation is going into the mainstream use of solar PV, which has become the direction. Inverter with the control design determines the effect of the operation of the whole system, which is a key part of PV. In this paper, a complete PV power system has been designed, focusing on the single-phase PV grid system, and adopts TI's new TMS320F2812 (DSP) as the main control center. designed hardware of single-phase PV inverter system, entire process software design is given. the photovoltaic inverter control system tests shows that the design of photovoltaic grid-control system has high control precision, higher efficiency inverter, and less distortion of the system.
