摘要
Due to the different manufacturing process and control mode, the commutation torque ripple will occur in the operation of BLDCM(Brushless DC motor). In this paper, the problem of BLDCM torque ripple is analyzed theoretically. In order to suppress the torque ripple during commutation, a method of combining Cuk converter with power inverter circuit is proposed. By changing the bus voltage, the DC bus voltage can be reduced at low speed and increased at high speed, so that the torque ripple of BLDCM can be suppressed at full speed. The simulation results are verified by MATLAB/Simulink, and the simulation results show the effectiveness of the method.
