摘要
应用开关函数建立了三相三电平中点箝位(NPC)PWM整流器的数学模型,在此基础上提出了应用于该整流器的基于两种坐标系的直接电流控制方法,即静止坐标系下abc电流控制法和旋转坐标系下i_d、i_q电流控制法。实验结果验证了该控制方法的正确性和可行性。
The mathematical model of three-phase three-level neutral-point-clamped (NPC) woltage source rectifier (VSR) using switching functions is founded firstly. Based on the mathematical model, the direct current control strategy for the rectifier in two kinds of reference frames called abe current control and id iq, current control are proposed. The experimental results verify the correctness and feasibility of the proposed control method.
