Simulation And Design Of Three Phase Inverter Based On SVPWM

Energy is the most important source of people’s life and economic development. After the second industrial revolution, the main use of coal, natural gas, petroleum and other human energy, however, the energy is limited, along with the rapid development of economy and the sharp increase of population quantity increasing, energy exploitation, energy exploitation whilesatisfy the human normal life demand, but it brings the problem of environmental pollutiongreat. In order to solve this problem, the human development of new energy, such as nuclear energy, wind energy, solar energy, new energy development will not cause any pollution to the environment. Especially these years the development of photovoltaic industry, greatly promoting the use of solar energy, photovoltaic inverter technology is becoming more and more mature, and to enter the market.Inverter is widely used, along with the increase of automobile amount, the inverter into the automotive field, which brings great convenience for human. In the photovoltaic field, the inverter is an important part of the photovoltaic industry. This paper first introduces the present research status at home and abroad, the significance of the inverter inverter; inverteris also widely used in wind power generation. Secondly, the paper introduces the technology of PWM for a long time the application in inverter; control technology and vector control technology and space of the three-phase inverter(SVPWM) are derived and analyzed in detail. On this basis, the use of MATLAB/SIMULINK for the various modules of the system was built and the simulation, the simulation design and operation of a three-phase open loop and closed loop of the inverter system, and the three-phase power inverter of the results were analyzed,include harmonic component(THD) analysis. Complete the hardware designbased on DSP chip TMS320F2808 for three phase inverter controller based on simulation,including the minimum system, IGBT bridge driving circuit, protection circuit design. The software adopts interrupt mode and up-down counter more.
