9KHz-500MHz LISN companion line impedance stabilization network 12V1A differential common mode separation module common mode outThe use of differential common mode separation: The difference and common mode separation extract the differential mode and common mode components, and provide direction for the design and rectification of the filter. What frequency band needs to use the common mode filter, at least how many dB need to be attenuated, and which frequency points need differential mode filtering.The main parameters: 1. Length 38mm, width 29mm, height 18mm. 2. Frequency range: 9KHz-500MHzMeasured comparison: Take the experimental No. 2 power supply in the introduction of LISN as an example, 12V1A is connected to a 12ohm load. The data tested in a third-party laboratory can be seen that the harassment is mainly before 10MHz.With the self-made LISN, the experimental No. 2 power supply 12V1A is connected to a 12 ohm load, and the test frequency range is from 9 KHz to 10 MHz. The disturbance on the L line is as follows:Then use the differential common mode separation module to separate the common mode signal:The image processing software is used to superimpose the above two pictures. For convenience of explanation, the red line is used to outline the disturbance contour on the L line. The common mode signal uses green lines. The difference between the red and green lines is the differential mode disturbance:Obviously, the difference between 1MHz and common mode coexists, mainly differential mode, 1MHz or more difference, common mode coexistence, mainly common mode.Packing: IPCranty period: 120 days
