Can a high frequency transformer loop problem cause abnormal noise?
Mar 01, 2017

   

      Can a high frequency transformer loop problem cause abnormal noise?


High-frequency transformer loop problem will cause high-frequency transformer abnormal sound: high-frequency transformer loop problem refers to the high-frequency transformer loop oscillation and cause high frequency transformer howling.

 

1. Improper wiring of the circuit board, resulting in interference caused oscillations, resulting in the sound;

 

2. Improper setting of the feedback loop parameters causes the loop to be unstable, causing oscillations and sounds;

 

3. The quality of the components in the loop, such as the input filter capacitor capacity is insufficient, the quality of the output rectifier fast recovery diode is not good, the quality of the power MOS transistor is not good, the quality of the high-voltage capacitor or diode of the RCD recoil absorption loop is not good, etc. These problems can cause shocks and cause noise.

 

The high-frequency transformer manufacturer Chen Fei summarizes: The high frequency transformer loop problem refers to the high frequency transformer loop oscillation causes the high frequency transformer to whirl, everybody must pay attention!
