Abstract

Electro-magnetic interference (EMI) in the boost active power factor correction (APFC) power supply circuit occurs due to common mode (CM) and differential mode (DM) noise. Performance of conducted EMI varies depending on different parasitics and EMI filter elements such as Y capacitor, CM choke and variation of the switching frequency. Furthermore, load variation impacts the level of EMI in the circuit. This paper analyzes the EMI noise variation in boost APFC circuit due to the change of circuit when circuit parasitics, switching frequency and load conditions are changed. The results of this work provide guidance for the EMI filter design of boost APFC power supply circuit to meet the strict electromagnetic compatibility (EMC) standard, such as Federal Communication Commission (FCC) class B.
