Abstract

Proposed New Method to Measure Common-Mode Current on High Frequency Circuits

Highlights

  • In the beginning of improvement era of electrical devices a lot of considerations were ignored in the electrical industrial about safety and environment

  • The hardest test to pass is the radiation emissions where the device is tested by measuring how much electrical and magnetic waves are emitted by the equipment under test

  • Common-mode current is a main source of electromagnetic interference

Summary

Introduction

In the beginning of improvement era of electrical devices a lot of considerations were ignored in the electrical industrial about safety and environment. After having a lot of experimental and getting a lot of results analyzed, scientists showed these were happened due to the electromagnetic wave interference. That is led to have the Electromagnetic compatibility (EMC's) standards to ensure the human's and other electric devices' safety. (EMC) has four main tests which are radiation emission, tradition immunity, conducted emission and conducted immunity. The hardest test to pass is the radiation emissions where the device is tested by measuring how much electrical and magnetic waves are emitted by the equipment under test. Common-mode current is a main source of electromagnetic interference. Electromagnetic radiation interference [2]. Measurement of common-mode current (CMC) is very important to estimate the electromagnetic radiated waves. This paper reviews some used technics to measure CMC and a proposed a new portable tools to measure the magnitude of (CMC)
