摘　　要：介绍了ISO7637-2《道路车辆--由传导和耦合引起的电骚扰:第2部分沿电源线的电瞬态干扰》。为了实现对车载设备电源瞬态传导干扰的抑制,提出了一种基于MOSFET开关的电路设计方案,说明其和传统滤波电路的不同,通过试验验证说明其较好的达到了设计要求。Introduce the ISO7637-2, Road vehicles-Electrical disturbances from conduction and coupling-Part 2： Electrical transient conduction along supply lines only. In order to restrain the Electrical transient conduction of the motor device, the design of the circuit based on the MOSFET is designed in this paper. The differences between the MOSFET circuit and the traditional circuit are also explained. The experiment and application show that this circuit has good performance, and achieve the design requirement.
