Am rema,want to know about an efficient common mode hybrid filter used in SMPS for my seminar 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

HIGH-DENSITY EMI FILTER DESIGN FOR DC-FEDMOTOR DRIVES



INTRODUCTION

Electromagnetic interference (EMI) is one of the major design challenges in motor drive systems, especially in applications where stringent standards need to be followed. EMI noise is usually defined as common-mode (CM) and differential-mode (DM) noise. CM noise is defined as the noise flows between the power circuit and the ground, while DM noise is defined as the current following the sam ....etc
