复合型多电平加载电机驱动器的研究

In the electrical load simulator system, topology and control methods of load motor driver directly affect the accuracy of load torque and dynamic response. For the H bridge two-level driver function, such bad issues should be considered, impact of high torque ripple, low speed of rotor energy conversion, low system bandwidth. In order to raise loading bandwidth and capabilities, we point out a topology and control strategy. The simulation results indicate that the new motor driver has a loading bandwidth higher than 8Hz and better performance.
