摘　　要：在长线电缆传输高频脉宽调制(PWM)脉冲的过程中,逆变器输出端通常用RLC滤波器来抑制电机端过电压和高频振荡,但对相关滤波器参数优化设计的研究较少。基于滤波器电感、电容最小值与PWM脉冲上升时间与滤波器电阻之间的定量关系,对上升时间和滤波器电阻的选取原则进行改进,从而有效减小滤波电感和电容,实验验证了所提改进方法的合理性。Resistance-inductance-capacitance（RLC） filters are usually used at the inverter output side to suppress overvoltage and high-frequency-oscillation at the motor terminal in the process of the transmission of high-frequency PWM pulse.However,there is little research on filter parameter optimization.Based on the quantitative relationship among the minimum of the filter inductance,capacitance and PWM rise time,the filter resistor.The paper improve the selection principle of the rise time and the resistor,which can reduce the inductance and capacitance effectively,experiment verify the rationality of the proposed improved method.
