Electromagnetism interference and restraining technology of SMPS

Wang Jingbin

Abstract

There is a prominent electromagnetism interference for switch power source due to itself mechanism,which has a great electromagnetism pollution to electronic equipment and communication system through conduction and radiation of its interference signal.The paper analyzed the reasons that the switch power source causes electromagnetism interference,summed up means to restraining electromagnetism interference such as filtering,shield,grounded.
