| Abstract: | Because of switch power＇s own work principle, the problem of electromagnetic interference is very prominent. Its jamming signal through conduction and radiation will produce electromagnetic pollution to electronic equipment and communication system. This paper mainly analyzes the reasons of electromagnetic interference＇ s generation and sums up the measures of its elimination such as ： filter, shielding, grounding. |
