N2 - Active power filter (APF) is one of major power quality controllers to deal with harmonics issues. It can compensate the low frequency harmonic components in power system by using PWM method. But, being a kind of switching power converter, APF will generate electromagnetic noise in high band. In this paper, the mechanism and path of two kinds of noise are analyzed and an EMI filter is designed to decrease the EMI noise. For APF, whose output current frequency may over 1250Hz (for compensate 25th order harmonic component in 50Hz system), EMI filter may deteriorate its compensation performance. The Multi-modular approach has been applied in the paper to achieve high equivalent switching frequency and reduce the switching ripple.
