The external interference generated by the power adapter, such as power line harmonic current, power line conduction interference, electromagnetic field radiation interference, etc., can only be solved by reducing the interference method. On the one hand, you can enhance the input / output filter circuit design, improve the performance of the active power factor compensation (APFC) circuit, reduce the voltage and current change rate of the switching tube and rectifier, current-continuing diode, using a variety of soft switching circuit topology structure and control mode, etc.; on the other hand, strengthen the shielding effect of the case, improve the gap leakage of the case, and good grounding treatment.

In the propagation path, appropriate increase in high anti-interference ability of TUS and high-frequency capacitors, ferrite beads and other components to improve the anti-interference ability of small signal circuits; small signal circuits closer to the chassis, should be added to the appropriate insulation withstand voltage processing, etc.; power device heat sink, the main transformer electromagnetic shielding layer to be properly grounded; the large area between the control unit grounding with grounding plate shielding; in the rectifier Rack, to consider the electromagnetic coupling between the rectifiers, the entire ground arrangement, etc., to improve the stability of the internal work of the power adapter. For the power adapter interference how to solve think you have a simple understanding, I hope that when you encounter this problem can be successfully solved!
