基于APF五电平逆变器永磁同步电机控制的研究∗

摘要

In order to improve the utilization ratio of energy, reduce the torque ripple and the harmonic harm, adding active power filter(APF) of the five-level inverter for permanent magnet synchronous motor control strategy research. Permanent magnet synchronous motor was established in the MATLAB 7. 8/Simulink model of APF five level control systems. And the simulation experiment was carried out. The simulation results showed that the application of APF five level control system of permanent magnet synchronous motor was correct.%基于提高电能利用率、减小转矩脉动并减小谐波危害的目的，采用加入有源电力滤波器( APF)的五电平逆变器对永磁同步电机进行了控制策略研究。在MATLAB 7.8/Simulink中建立了永磁同步电机APF五电平控制系统的模型，并进行了仿真试验。仿真结果表明永磁同步电机APF五电平在控制系统应用的正确性。
