The problem of inductor abnormal sound noise
Jun 26, 2018

The problem of inductor abnormal sound noise 

The problem of inductor abnormal sound noise is related to the magnetic components, as well as the magnetic components, such as winding and tightness. Some winding wires can cause the inductor coil to sound, and the loosening of the coil will directly cause the inductor noise to be related to the circuit scheme or loop, which may be caused by the frequency mismatch.

It's also possible that there is something wrong with the switch circuit. If you look at the oscilloscope, it should not be a good rectangular wave. There should be a lot of clutter in it. The specific noise should be combined with the overall situation in the circuit.
