汽车用闪光继电器的无线电骚扰抑制技术

为适应国家推出的GB186 55—2002《用于保护车载接收机的无线电骚扰特性的限值和检测方法》,在分析汽车用闪光继电器工作原理及产生无线电骚扰原因的基础上,设计了2种解决方案。根据这2种方案的工作原理,在相同的条件下分别进行了电磁干扰噪声的测试。得出方案2完全符合要求,指出使用数字电路可以很好地解决开关电路引起的电磁兼容问题。

Radio Disturbance Restrain Technology of Flash Relay Used in Automobile

In order to adapt the GB 18655-2002,〈Limits and methods of measurement of radio disturbance characteristics for the protection of receivers used on board vehicles〉, based on analyzing the principle of automotive flash relay and the reason of radio interference, two methods were designed. On the basis of their principles, electromagnetic disturbance noise was tested under the same condition. Then a feasible solution of reducing the automotive flash replay radio disturbance is put forward
