摘　　要：详细介绍了SVPWM的原理。采用一种易于数字化实现的SVPWM算法实现三相电压型SVPWM整流器,该整流器采用dq坐标系下的双闭环控制。给出了PI调节器参数,以及主电路电感、电容的计算公式。在Matlab Simulink环境下搭建整流器仿真器模型。仿真结果表明,整流器能实现单位功率因数整流和能量双向流动,验证了SVPWM算法和控制系统设计方法的正确性。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 SVP-WM algorithm and the method of control system design in this paper are correct.
