Am rema,want to know about "an efficient common mode hybrid filter used in SMPS for my seminar and presentation work.

Abstract obtained from IEEE is " After the study of electromagnetic interference (EMI)
mechanisms in switching mode power system (SMPS) and the soft
switch, this paper proposes a novel hybrid filter (HEF) to suppress
commend mode EMI in SMPS. The HEF consists of a passive filter
and an active filter. Matching network, which can reduce
impedance mismatching effects, is introduced in passive part. A
feed-forward active filter is adopted as active part. The simulation
and experiment results show that the EMI depressing of HEF is
good. And the HEF is smaller and lighter than traditional passive

it is about hybrid EMI filter which incorporates
a LC passive filter and in active
part, a feed-forward filter is adopted
