The electromagnetic interference level of the power supply is the most difficult part of the design, the designer can do the most is to make full consideration in the design, especially in the layout.
Since DC to DC converters are often used, hardware engineers are more or less exposed to related work, and we will consider two common tradeoffs related to the design of low EMI. Even the ordinary DC to DC switch converters in the design of the power supply can have a series of problems, especially in the design of high power power supply. In addition to functional considerations, engineers must ensure the robustness of the design to meet cost objectives and thermal and spatial constraints, while ensuring the design progress. In addition, for product specifications and system performance considerations, power generation of electromagnetic interference (EMI) must be low enough. However, the electromagnetic interference level of the power supply is the most difficult to accurately predict the design of the project. Some people even think that this is simply impossible, the designer can do most is in the design of the full consideration, especially in the layout.
