Abstract

Conducted emission tests are always performed by the use of LISNs in laboratories in accordance with CISPR22, CISPR11 and other similar standards. However, it is not always possible to use LISNs because of some limitations. If the Equipment Under Test (EUT) has large dimensions or high currents, it is not, for most of the time, possible to send it to an EMC laboratory or to use LISNs during the test. As a consequence, usage or development of alternative conducted emission test methods are inevitable in industry. In this paper, we investigated the use of LISN simulations constructed with long ordinary cables, capacitors and resistors instead of actual LISNs. In addition, we also improved the usage of CISPR16 Voltage Probe by combining it with impedance measurements of EUT, supply and used cables.

使用LISN仿真和CISPR 16电压探头进行替代发射测量
进行的发射测试总是按照CISPR22、CISPR11和其他类似标准,在实验室中使用lisn进行。然而,由于一些限制,并不总是可以使用lisn。如果被测设备(EUT)尺寸大或电流大,在大多数情况下,不可能将其送到EMC实验室或在测试期间使用lisn。因此,在工业中不可避免地要使用或开发替代的传导排放测试方法。在本文中,我们研究了使用长普通电缆,电容器和电阻来代替实际的LISN模拟。此外,我们还通过将CISPR16电压探头与EUT、电源和使用电缆的阻抗测量相结合,改进了CISPR16电压探头的使用。
