摘要

与FCC和军事标准要求相比,汽车行业的辐射发射(RE)合规性要求是EMC工程师面临的最困难的设计挑战之一。最近对EMC要求的修订大大提高了可再生能源的合规性水平。汽车工业的辐射排放要求跨越了很宽的频率范围(150 kHz-1.583 GHz)。欧洲长波(150 kHz-280 kHz)和全球中波调幅波段(0.53 MHz-1.7 MHz)是本文的主题。现代车辆中用于接收射频服务的车载接收器,表示为低频低频和毫瓦音频广播,可能容易受到意外噪声源的影响。现代汽车的噪声源十分丰富,其电气、电子元件数量众多。由于现代车辆中集成了电子设备,因此它创造了最苛刻的电磁环境。

Automotive AM-band radiated emission mitigation techniques, a practical approach
Radiated emission (RE) compliance requirements of automotive sector demands one of the most difficult design challenges for EMC engineers as compared with those of FCC and military standard mandates. Recent revisions to EMC requirements has exasperated the RE compliance levels considerably. Automotive industry radiated emission requirements span over a wide frequency range (150 kHz-1.583 GHz). The European Long Wave (150 kHz-280 kHz) and global Medium Wave AM band (0.53 MHz-1.7 MHz) is the subject of this article. Onboard receivers in modern vehicle intended for the reception of the RF services, indicated as low frequency LW and MW audio broadcast, can be susceptible to unintended noise source(s). The modern vehicle is abundantly rich in noise source with a large number of electrical and electronics components. As a result of integration of electronics in modern vehicle, it hence creates the most demanding electromagnetic environment.
