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 ...

In switching power supplies, there are two common types of noise: common mode noise and differential mode noise. The noise with the same path as the input signal is called differential mode noise, while the noise from ground to output with the same phase is called common mode noise. Common mode inductance can suppress common mode noise and improve signal quality through filtering. As for power lin...
