【技术】汽车电子电路安全隐患的最佳解决方案
安全性在汽车设计中至关重要。汽车价格昂贵,所以保护车主的财产安全是很有必要的。最重要的是,如果汽车的安全性有问题,那么人们的生命也将处于危险之中。这就是为什么现代汽车制造商融合了各种安全保护功能,包括安全气囊,稳定性控制和胎压监测等。但是对于设计安全性的考虑,远远超越了这些明显存在的保护系统。对于汽车内的任何电子设备来说,无论大小如何,安全性都是设计考虑的重要因素。
无论是在引擎盖下还是在驾驶室内,当今先进的芯片组都非常容易受到苛刻的汽车环境中常见的众多电气危害的影响。典型的汽车电气危险或瞬变包括电力电子电路中的雷电,静电放电(ESD)和开关负载等。
负载突降带来的问题
在现代汽车设计中,所有车载电子装置都连接到了电池和交流发电机上。交流发电机是电压瞬变的主要来源,其中最严重的就是负载的突变。当交流发电机发电并且其他负载留在交流发电机电路上时,放电的电池断开也会发生这种情况。如果放在一起,电力尖峰和瞬变会沿着电力线传输,将导致单个电子设备/传感器故障或车辆电子系统永久性损坏。当然,不受控制的降负载会威胁车辆的安全性和可靠性。
汽车负载突降保护
包括瞬态电压抑制(TVS)二极管和压敏电阻在内的电路保护器件是保护敏感电子器件免受降负载影响的最佳方式。TVS二极管的选择是依靠硅雪崩器件的快速响应时间(低钳位电压)和低漏电流的优点,而且因为它们没有固有的损耗因数。压敏电阻通常用作瞬态浪涌保护的前端解决方案。例如,超小型表面贴装多层压敏电阻(MLV)器件用于保护小型电子设备和传统的中档金属氧化物压敏电阻(MOV)用于保护小型机器,电源以及元件。
在大多数现代交流发电机中,通过在干扰源处添加限制性TVS二极管,使负载突降振幅被抑制或限制。应通过抑制(TVS二极管)器件在内部或源端抑制干扰瞬变。作为最佳做法,设计人员应尽可能将TVS二极管靠近源极。图一展示了TVS二极管的位置以及受到保护的电路。
图一 TVS二极管的位置以及受到保护的电路
用于防止交流发电机瞬变的其他电路保护解决方案,涉及使用符合AEC-Q200标准的MOV,可以考虑下面的例子:
•图二展示了一个AUMOV压敏电阻可以连接Y形或者三角形配置,与交流发电机的绕组线圈连接,来钳位瞬变。
图二 AUMOV压敏电阻的瞬变保护
•图三展示了使用AUMOV压敏电阻保护汽车子系统(如安全气囊,动力总成,气压控制)。 将其用作瞬态浪涌的分流器,以保护直流电源线不受浪涌影响。

•图四展示了为了防止汽车继电器浪涌,使用AUMOV压敏电阻来吸收由继电器磁场释放的能量产生的电弧能量。
