摘 要: 随着各种新型电力电子设备的广泛应用,有必要对整流桥输出的电磁干扰进行分析预测,以保证系统的正常工作。以整流桥直流侧的电压跳变为干扰源,结合实验测试对三相整流桥输出端的干扰进行了理论分析和预测,实验结果证明了预测的正确性。提出的方法也可用于其他电力电子设备的电磁干扰分析。 On the basis of the calculation and experiment for the frequency domain method, the electromagnetic interference (EMI) which generated by the phase rectifier is analyzed. The step voltage in the DC side is considered as the noise source, and the propagation path is determined by the LISN.Then the noise spectrum is calculated by the equivalent circuit. The experiment results verified the validity of the calculation.
