The conduction disturbance (CE) at the power supply end exceeds the standard, but it doesn’t move even after adding a common mode inductor? VOOHU explains the causes from the two noise paths of differential mode and common mode, analyzes the selection logic of peak impedance, DC bias and leakage inductance of common mode inductors, and provides a selection table and three-step rectification method for the on-shelf material numbers of common mode inductors and integrated inductors of power lines.

In audio systems, speakers and amplifiers are often the focus of discussion, while the audio transformer, a crucial component, is frequently overlooked. In reality, it plays an indispensable role in ensuring sound purity, reducing background noise, and ex
