摘要
提出了一种无线路阻抗稳定网络(LISN)的传导干扰替代测试方法。在建立被测对象的共模(CM)、差模(DM)等效电路模型基础上,获取回路阻抗及回路电流等效替代的校正因数。并以开关电源为例,结合其实际工作状态,对其工作在空载和带载状态下的传导干扰测试等效替代方法进行了研究。实验结果证明了所提替代方法的可行性,实现了实验室与实际应用工况下传导干扰测试的等效替代。
An alternative conducted emission test method without line impedance stabilization network(LISN) is proposed.On the basis of establishing the common mode(CM) and differential mode(DM) equivalent circuit model of the measured object,the correction factors of loop impedance and loop current equivalent substitution are obtained.Using a switched-mode power supply as an equipment under test,combined with its actual working state,the equivalent alternative method of conducted emissions measurement under no-load and on-load conditions is studied.The feasibility of the proposed alternative method are proved by the experimental results.Finally,an equivalent substitution of conducted emission measurement is established between the laboratory and the application environment.
