Abstract

One of the most challenging and interesting field in power electronics is the ability to mitigate the Electromagnetic Interference (EMI). A natural source of EMI includes the atmospheric discharge/charge phenomena and extra-terrestrial radiation. Man-made source of EMI are line radiation, auto ignition, radio frequency interference and power lines. Suppression of EMI and enhancing the Electro Magnetic Compatibility (EMC) has become essential in high frequency power electronic converters. This review article is a one stop solution for new researchers and practitioners to understand about the effects of EMI and its suppression techniques in detail.

Summary

INTRODUCTION

The invention of power electronics has created a revolution in the life of mankind. Power electronics have brought about ground-breaking changes in domestic and industrial applications [1]. The simplest converter topology adopted for faithful reproduction of higher output voltage for a given input voltage is DC-DC boost converter. It finds a wide range of applications covering front end converters for battery sources, solar PV systems and fuel cells [8]–[10]. Various methods have been described in the literature to suppress the EMI and to meet the EMC standards. These methods can be broadly categorized into: EMI Filter EMI Shielding Soft switching Random Modulation and Chaotic PWM control. EMI mitigation is extremely important for researchers and engineers working in the field of EMI suppression [18]–[21]
