Abstract：In order to reduce the total harmonic distortion of grid inverter, the study establishes its mathematical model in the three-phase static coordinate system and studys the SVPWM modulation technology used in the three-phase inverter, according to the working principle of three-phase inverter.Also it gives the inductance parameter selection principle under this kind of control technology, analyzes the different connection of the transformer secondary side and DC magnetic biasing influence on total harmonic distortion, and the improved method is proposed.A three-phase inverter used SVPWM modulation strategy under the Matlab/Simulink environment is simulated, a three-phase inverter experimental prototype based on DSP control is built, and the grid experiment is carried out.The experimental and simulation results show the feasibility of the research methods and control strategies.
