    Common Mode Choke

    Common Mode Chokes When we said a common mode choke, it means it was wound both line and neutural windings on a single core. Since the noise would be common mode noise usually, the way to lower (if not eliminate) the unwant noise frequencies is to use a common mode choke As below picture show us details of Common-Mode Signals Defined: Such signals can arise from one or more of the following source...

    The reasons that inductance can eliminate EMC

    During EMC power supply circuit design, common-mode interference is the most difficulties encountered, common mode inductor is one of the major methods on solving interference signals. Here let's talk about the basic principles of solving EMC artifacts from design plan in this way. A common mode inductance, is wound both line and neutural windings on a single core. While the magnetic flux in ...
