Electromagnetic Interference (EMI) & Electromagnetic Compatibility (EMC)

INTRODUCTION

¢ EMI-

It consists of any unwanted conducted or radiated signals of electric origin that can cause degradation in system or equipment performance.

¢ EMC-

It is the ability of the system to function as designed without any degradation in performance due to EMI with in the operational environment

proposes an autonomous train control system based on inter-train communication. In this new system, there is no logical central device and trains can communicate with each other autonomously. The train itself produces the position and calculates the permitted track speed. Therefore, the distance between trains can be shortened and a smooth brake pattern can be obtained. For building this system without hindering the current system operations, the gateway-based replacement technology and its test methods are explained. The assurance of test meth ....etc

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

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
