| Abstract: | Switching power supply is widely applied in the fields of communication, control, computer and other fields due to its small size, higher power factor and other advantages,but whose electromagnetic interference restricts its use. The related concept of electromagnetic interference in the switching power supply is introduced, the mechanism produced by electromagnetic interference of the switching power supply is analyzed. The electromagnetic compatibility method of the switching power supply is implemented, the commonly used interference suppression measures in the switching power supply is presented combined with the actual practice. |
