In this presentation we will be taking a look at a common mode choke simulation:
-
Simulation assuming linear core.
-
Simulation with saturated ferrite.
-
Simulationwith Partial RLCsolver.
The presentation this material is based on can be found as application note QA00000066706 (How to simulate Common Mode Choke components in CST Studio Suite?) on our Knowledge Base (https://www.3ds.com/support/knowledge-base/).
A common mode choke is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing the desired DC or low-frequency signal to pass. Common mode (CM) noise current is typically radiated from sources such as unwanted radio signals, unshielded electronics, inverters and motors. Left unfiltered, this noise presents interference problems in electronics and electrical circuits.
