Tips: What should I do if the switching power supply makes noise?

Add filter
Adding a filter is a very common way to suppress switching power supply noise. If the power supply is disturbed by external disturbances such as lightning strike and artificial noise, the malfunction will cause great disturbance to the system. If a filter is connected to the AC input, the generation of this disturbance can be effectively reduced, and the disturbance can be reduced in time. The noise that occurs inside the switching power supply does not leak out from the input.
Grounding measures
The purpose of grounding the power supply is for safety reasons, and the electromagnetic compatibility problem can be effectively solved after the grounding of the power supply. Reducing Electromagnetic Disturbance. A good grounding system plays a vital role.
Other measures
In addition to the above measures to effectively suppress the noise of the power supply, we can also start to reduce the noise impact of the switching power supply in terms of the position and direction of component installation, the overall configuration of the system circuit, etc.

To sum up, the noise of switching power supply is affected by many factors. In order to effectively suppress the noise of switching power supply, the relevant staff should pay attention to the analysis of noise of switching power supply, fully grasp the overall situation of the switching power supply, carry out effective management, promote the upgrading of the switching power supply, and improve the use function of the switching power supply.
