| Abstract: | This paper describes the principle of SVPWM,using an algorithm easily to digital implement.The rectifier uses a double-loop control in the dq coordinate system.Formula of PI regulator's parameters,and the inductance,capacitance of the main circuit is given in this paper.Construct rectifier emulator model in the environment of Matlab Simulink.Simulation results show that the rectifier can achieve unity power factor rectifier and energy can flow in both directions.It is verified that the SVPWM algorithm and the method of control system design in this paper are correct. |
