摘要
针对如何提高电机运行的平稳性和减少因谐波所带来的振动和噪声,设计了一种安装在PWM逆变器输出端的RLC滤波器,经过优化的RLC滤波器使电机端的高次谐波含量明显降低,电压、电流脉动现象得到了较好地抑制,并在Matlab/Simulink平台上进行仿真实验,验证了文中所设计滤波器的有效性和可靠性。
Based on the analysis and research of the PWM variable frequency speed regulating system of brushless DC motor,this paper introduces a new kind of RLC filter which can be installed on the PWM inverter output end to improve running stability of the motorand reduce vibration and noise brought by the harmonic. After optimization of RLC filter makes the motor end higher harmonic content is significantly reduced,voltage,current pulsation phenomenon is suppressed,and the simulation results in Matlab / Simulink platform,verify the validity and reliability of the designed filter in this paper.
