摘要
深入研究感应电机驱动系统传导电磁干扰机理问题,对于由脉宽调制(pulse width modulation,PWM)功率变换器产生的电磁干扰源,提出将各开关状态分为2种模式,并结合负载电流的各个不同水平,建立各开关状态下的噪声源模型组合,感应电机驱动系统噪声源可根据这些组合联立获得。针对感应电机驱动系统中长线传输时电压反射现象及其造成的电机端过电压,建立长线电缆的高频传输线模型;分析感应电机绕组的高频特性,根据传输线理论,建立简化的感应电机高频等效模型。根据精确的噪声干扰源模型、长线电缆模型和电机模型,构建感应电机驱动系统"干扰源-传播路径-受扰体"的整体传导电磁干扰预测模型,实现其传导电磁干扰的有效预测。
The mechanism of conducted EMI was investigated deeply in induction motor drive systems. For modeling conducted EMI source in induction motor drive systems, a new module approach was proposed to predict conducted EMI. The different switching conditions can be classified as two models, and combined with the different zones of load current. A family of different noise source models was built. The whole conducted EMI source in induction motor drive systems can be obtained from the sum of the different noise source models. A long transmission line was connected between power converters and motors to transmit PWM pulses.Because of the voltage reflection phenomena and the over-voltage in motor terminal, it is necessary to build the high-frequency transmission line model. The high-frequency characteristic of motor winding was analyzed. According to the transmission theory, the high-frequency model of induction motors was constructed for predicting conducted EMI precisely in induction motor drive systems. Based on the precise noise sources model, high-frequency model of transmission line and high-frequency model of induction motor, the whole model in the form of "noise source-propagation path-motor" was built for predicting the conducted EMI accurately of induction motor drive system.
