摘要
针对开关电源的电磁干扰抑制原理,设计了电磁干扰滤波器磁芯,包括共模感应器材料的选择,磁芯线圈的计算。通过电磁干扰滤波器的设计实例分析,使设计者理解和选择最适宜用于特殊用途的铁氧体材料和成分,掌握共模感应器的设计方法和实际应用中应注意的问题。
Aiming at the suppression principle of switch power supply EMI, this paper designs the magnetic core of EMI filter, which includes the choice of common-mode inductor's material and the calculation of magnetic core's winding. With the analysis of EMI filter's design as an example, this paper could help the designer understand and choose the ferrite material and component which are optimum for their special purpose, master the design method and attention points in actual application.
