| description | The invention belongs to the research field of power electron and electromagnetic interference and discloses a common mode/differential mode noise discrimination network. The network comprises two line transformators which are in parallel connection, the driving point impedances of the two line transformators are both100 omegas so that Zin1=Zin2=50 omega is precisely guaranteed and the network can better play the role of the frequency bandwidth of the line transformators; meanwhile, a compensation capacitor is added to ensure that the driving point impedances of the common mode/differential mode noise discrimination network are kept within 50 omegas. The common mode/differential mode noise discrimination network can reach impedance matching of separate meshes, realizes that the network always keeps the characteristic impedance of 50 omegas in the 30 MHz broad band, and can be applied to various common mode/differential mode separations which can conduct electromagnetic noise. |
