摘　　要：针对汽车轮胎气压监测系统(TPMS)抛负载瞬态传导抗扰性试验,结合《GB/T21437.2 idt ISO7637.2沿电源线的电瞬态传导》标准,提出了TPMS接收模块对脉冲5 a/5b耐受程度试验原理及其方法,同时分析了自恢复保险管和瞬态抑制二极管电路特性,据此提出了被测设备电路优化设计方法.实验结果表明,采用文中优化电路可提高TPMS主机接收模块耐受汽车抛负载电瞬态传导脉冲干扰的能力,从而对汽车电子电磁抗扰度提供理论依据.According to the standard 〈GB/T21437.2 idt ISO7637.2 Electrical transient conduction along supply lines only〉,the principle of transient conduction immunity test for automobile load dump on TPMS with 5a/5b pulse was proposed.The circuit characterizations of positive temperature coefficient（PTC） resettable fuse and transient voltage suppressor（TVS） were analyzed,and the optimized circuits of equipment under test（EUT） were designed.Experiment results show that the ability to conduct pulse interference tolerance for TPMS could be improved by employing the suggested optimized design.
