Abstract

There are more and more application scenarios of switching power supplies. The electromagnetic interference between various electronic devices makes the working environment of the power system more and more severe.The electromagnetic compatibility of the power system has attracted more attention. This study analyzes the design process and main design parameters of the power supply filter for the conduction interference problem of the power supply port

and develops a miniaturized and high insertion-loss power filter to effectively solve the electromagnetic conduction interference problem of the switching power supply

thus to ensure stable operation of the power system.
