What is the interference with the power adapter?
For external anti-jamming capabilities, such as surges and lightning strikes, the lightning protection capability of the AC input and DC output ports should be optimized. The lightning strike can be solved by a combination method of a zinc oxide varistor and a gas discharge tube.
Reduce the area enclosed by the high voltage and high current lines, especially the primary side of the transformer and the switching tube and the power supply filter capacitor circuit; reduce the area enclosed by the output rectifier circuit and the freewheeling diode circuit and the DC filter circuit; reduce the leakage inductance of the transformer, The distributed capacitance of the filter capacitor; a filter capacitor with a high resonance frequency is used.
To reduce the internal interference of the power adapter, we should start from the following aspects: pay attention to the single point grounding of the digital circuit and the analog circuit, and the single-point grounding of the large current circuit and the small current, especially the current and voltage sampling circuit, to reduce the common resistance interference. Reduce the influence of the ground loop; pay attention to the spacing between adjacent lines and the signal properties when wiring, to avoid crosstalk; reduce the ground impedance.
For electrostatic discharge, use TVS tube and corresponding grounding protection, add the distance between the signal circuit and the casing, or use the device with anti-static interference to solve.
