Abstract

This paper demonstrates that using conventional frequency scanning methods for the evaluation of conducted electromagnetic interference generated by DC/DC converters can give misleading results when pseudo-random modulation is used as part of the converter control scheme. The paper therefore proposes that the resolution bandwidth of the super heterodyne EMI test receiver used for measurements and the dwell time should be adjusted to match the control parameters of the random modulation scheme. The use of different values for resolution bandwidth and dwell time is demonstrated and measurements for random and fixed modulation schemes are compared.

伪随机调制对测量传导电磁干扰的影响
本文证明,当采用伪随机调制作为变换器控制方案的一部分时,用传统的频率扫描方法来评估DC/DC变换器产生的传导电磁干扰会产生误导的结果。因此,本文提出应调整用于测量的超外差电磁干扰测试接收机的分辨率带宽和驻留时间,以匹配随机调制方案的控制参数。演示了不同分辨率带宽和驻留时间值的使用,并比较了随机和固定调制方案的测量结果。
