【摘要】 对逆变器驱动感应电机时的负面效应进行了分析,提出了一种考虑负载效应的逆变器输出滤波器优化设计方法。优化结果既能满足对滤波器幅频特性的要求,同时又能提高滤波器的负载应变能力。所设计的滤波器可以有效地减少逆变器输出PWM波形对电机轴承和定子绝缘材料的损坏。在逆变器输出滤波器研究平台上,对Rockwell公司1336plus Ⅱ逆变器驱动5 kW感应电机系统进行了实验研究和仿真分析,结果表明方法可以有效提高滤波性能。更多还原

【Abstract】 The negative effects of PWM Inverter-fed motor drive system are analyzed in the paper. An optimal design method of the inverter output filter considering load effects is proposed. The optimization results of the filter not only meet the requirement of amplitude-frequency characteristics, but also enhance the filter’s ability to adapt to various loads. The filter designed using this method can effectively reduce the damages of motor shaft and dielectric material caused by inverter output PWM wave. Simulation and experiment were carried out on the inverter output filter research apparatus driving a 5kw induction motor, the inverter is 1336 plus II produced by Rockwell. The results show that the proposed method can effectively improve the performances of the filter.更多还原
