In the design of high-power power supplies, the transformer plays an important role in the transmission and conversion of electrical energy. The design of the alignment under the transformer not only involves the power transfer efficiency of the circuit, but is also closely related to electromagnetic compatibility (EMC), thermal management and circuit reliability.
1. Layout
In the design of the alignment under the transformer, a reasonable alignment layout is the key. Excessive signal lines under the transformer should be avoided to reduce mutual inductive interference. At the same time, the alignment of the high-power power supply should be as short and straight as possible to reduce resistance and improve efficiency.
2. Ground design
Reasonable ground design is the basis for stable circuit operation. Under the transformer, the ground line should be as wide as possible to reduce current density, reduce resistance and improve conductivity. At the same time, care should be taken to avoid ground loops to prevent the formation of magnetic fields, affecting electromagnetic compatibility.
3. Current path
The design of the current path is directly related to the efficiency of the circuit. In the transformer below the line, should ensure that the current path is short and wide, reduce the impedance of the current through. Reasonable current path design helps to reduce power loss and improve the efficiency of the power supply.
4. Thermal Management
High-power power supplies are usually accompanied by a large amount of heat generation, so thermal management is an issue that cannot be ignored. In the design of the alignment under the transformer, heat conduction and dissipation should be considered, appropriate heat dissipation materials should be selected, and reasonable heat sinks should be set up to ensure the stability and reliability of the circuit.
5. Electromagnetic compatibility (EMC)
Electromagnetic compatibility is an extremely important aspect of high-power power supply design. When routing under the transformer, a series of measures should be taken, such as reasonable shielding, reducing electromagnetic radiation, etc., in order to prevent electromagnetic interference from adversely affecting other circuits.
6. Safety considerations
High-power power supply involves high voltage and high current, safety issues can not be ignored. The design of the alignment under the transformer should consider avoiding the crossing of high voltage and low voltage signals to reduce the safety risk.
The design of the alignment under the transformer is critical to the performance of high power supplies. When carrying out the design, it is necessary to comprehensively consider various aspects such as circuit layout, ground design, current path, thermal management, electromagnetic compatibility, and safety. By following reasonable design and precautions, the efficiency, stability and reliability of high power supplies can be effectively improved to meet the needs of various applications.
