| 摘 要： | 传导发射是沿电源线或信号线传输的电磁发射,在低频范围内,传导发射是电磁干扰的主要形式。如不采取措施,几乎所有的电子、电气设备电源线的传导发射都得超标,若将这些设备安装在飞机上,它将严重地威胁着机上其他设备的正常工作。本文对各种脉冲波形的频谱进行了比较,并对整流器的谐波发射进行了分析,最后介绍了降低传导发射的设计方法。

| Abstract: | Conduction emission is an electromagnetic emission transmitted on power or signal lines and a primary form of electromagnetic interference at low frequencies.The conduction emissions on power lines for nearly all electronic/electric equipment would exceed the limits specified in applicable standards,if no appropriate measures are taken.When such equipments are installed in an aircraft,they would severely interfere with operation of the other equipments in the aircraft.Spectrums of various pulse waveforms are compared and harmonic emissions from rectifiers are analyzed in this paper.Finally,design techniques to minimize the conduction emissions are presented. |
