Simulation of SVPWM Three-Level Rectifiers

The three phase voltage in ABC coordinate system can synthesize a rotational space voltage vector.The space voltage vector is adopted to control the rectifier AC voltage.After two-phase coordinate transformation,the phase angle of power voltage vector can be determined and the control of rectifier power factor can be implemented.The SVPWM simulation model a nd three-level SVPWM rectifier model are constructed under MATLAB SIMULINK environment.The control system is proposed and the three-level SVPWM rectifier system is simulated.Parts of the simulation waves are successfully given,but the waves still have some limitations because of imperfect of the control system.
