Research And Development Of Grid-connected Bidirectional Inverter Based On TMS320F2808

With the rapid development of national economy,its population grows larger, various energies consumption,wasting energy sources to make some people more discovery that they only depend on renewable energy is far from satisfactory..Therefore,seek and use utilization of regenerated energy will be a key focus of ongoing studies.Science have achieved great success in a new way for studying,making use of new energy in the world and how to yield the greatest returns on energies.Such as utilization of wind energy,utilization of solar energy,utilization of biogas energy,Some the use of new electronic device and so on,more and more these study will come into use in our daily life and production. Our country has a large population, although per capita energy consumption could still be very low. weighing heavily on growth in energy demand, energy supply and economic development is very outstanding under a condition of globalization, While the develop trend of new energy and renewable energy, it is very importance to improving the efficiency of energyBased on this background,this thesis study the circuit device with high power factor,it can increase effectively active power,reduce reactive power and avoid electricity grid side and load side waste.A circuit device of an Grid-connected Bidirectional Inverter device is presented,it give the operating principle and the main measures on how to control this circuit.The thesis give the matlab models of the main circuit,make use of SVPWM to produce pwm wave to control the IGBT turns off and turn on,at the same time,also make use of power feedforward decoupling,So we verify the correctness of the circuit when it work at rectifier pattern and inverter pattern.It also give the simulation results of the circuit,so we verify the correctness of and feasibility of the circuit.This paper introduces the development history of ti dsp, CCS3.3development environment,adjust circuit,core circuit,driver circuit by making use of M57962L.To meet the needs of the real-time Bidirectional Inverter in the electrical distribution system,This thesis studies real time operating system μC/OS-Ⅱ with open source code,simple operation embedded operating system as the software system of Bidirectional Inverter Device and and it was successful transplant to TI company dsp2808and achieves this platforms successful transplant and realized.At last, the paper also described the software overall thoughts and control procedures.
