摘要
采用AC/DC/AC拓扑结构,利用三电平PWM整流、逆变原理,构建了双馈电机控制变频器。采用简化的三电平SVPWM算法,外加中点电位控制,对整流和逆变进行仿真,仿真结果表明控制效果良好。同时,给出了双馈电机试验平台的整体硬件设计框图,实验证明了该方法对双馈电机控制的可行性。
Using the principle of three-level PWM rectifier and inverter, the AC/DC/AC main circuit topological structure is adopted to construct the converter, which is used to control the double-fed induction motor（DFIM）.A simplified SVPWM method for three-level inverter and the neutral point voltage control are adopted in the inverter block.The simulative results about the rectifier and inverter prove that the control affect is good.The hardware design of DFIM experimental platform is introduced, and the experimental results show that the control method is feasible.
