瞬态干扰在汽车电子模块电路上的计算和测试验证

Calculate and Test of Transient Interference in Circuit of Automotive Electronic Modules

随着汽车工业的快速发展,电子设备间的电磁干扰越来越复杂。介绍了国际标准ISO7637-2中规定的5种瞬态干扰脉冲,并且针对汽车座椅加热通风模块的电源电路,分别对5种瞬态干扰脉冲进行了相关设计计算和验证。结果表明理论计算和实验结果相一致,有效验证了该模块电源电路的设计正确性,为今后更复杂的车载模块设计奠定理论基础。

This paper introduces the five kinds of transient interference pulse in ISO7637-2.Design calculation and verification by using the five kinds of transient interference pulse respectively in view of the power supply circuit in the heating ventilation module of seat.Results show that the theoretical calculation and test results are consistent and effective.
