摘　　要：阐述一种可降低环形PFC电感分布电容的绕制方法,在300W开关电源中的应用,通过一种特殊的绕制方法来减小绕组间的分布电容,解决PFC电感在工作时,因流过大的高频电流产生的EMI噪声干扰。This paper expounds a winding method that can reduce the distributed capacitance of ring PFC inductance,and its application in a 300W switching power supply.A special winding method is used to reduce the distributed capacitance between windings and solve the EMI noise interference caused by the large high-frequency current flowing through the PFC inductance during operation.
