Compensation for current probe measurement applied in conductive electromagnetic interference (EMI) noise soft separation

In conductive electromagnetic interference (EMI) noise measurement, noise separation is important for noise diagnosis and suppression. Compared with conventional hardware-based separation, the noise soft separation, which is based on modern signal processing technique, is more robust, convenient and cheap. However, the non-ideal spectrum performance of current probes may have effects on the separation results. Thus in this paper, a compensation method is proposed for current probes applied in noise soft separation. Results show that the method is efficient in use.
