摘要
Abstract
Switching power works between dozens of kHz and 1 MHz. The electromagnetic interference (EMI) can generate coupling with the system through the transmission channel, which may harm the sensitive equipments and decrease the electromagnetic compatibility of system. In this paper, a simulation model of switching power supply DC-DC buck converter circuit is established in Saber, and the current in every branch is analysed in time domain and frequency domain. From the study, the sources and ways of harassment can be found. This method can be utilized to find out the sources of electromagnetic interference in the prophase of product development, which can reduce the level of electromagnetic interference and the cost of research.关键词
