| Abstract: | Abstract: Electromagnetic interference in high-PF flyback switching power supply is analyzed. EMI filter is designed to achieve EMC of Switching power supply. On the discuss of principles of EMI filter design, effect of high-frequency distribution parameters on the frequency characteristics of filter is determined. Design and adjustment of filter on their structures and parameters can effectively suppress conducted interference and help lamp with high-PF flyback switching power supply to meet EMC standard. |
