I-shaped inductance noise noise problem?
Aug 14, 2018

I-shaped inductance noise noise problem?

In addition to the magnetic components, the problem of abnormal noise of the word-shaped inductance is also related to the process, such as winding and tightness. Some windings will not cause the abnormal sound of the induction coil; and if the coil is loose, it will directly cause the inductance. The sound is also related to the scheme or loop of the circuit, and may be caused by a frequency mismatch.

There may be a problem with the switch circuit. If you look at it with an oscilloscope, it should not be a good rectangular wave. There should be a lot of clutter inside. The specific noise noise needs to be combined with the overall situation in the circuit.
