Do you know the main points of high-reliability power module planning?

Do you know about the planning of high-reliability power supply modules? Power supply modules are power converters that can be directly mounted on a printed circuit board. According to the conversion method, it is generally classified as AC-DC or DC-DC. With the development of technology, power supply capacity tends to be modularized and miniaturized, so power supply modules have appeared. It has a high degree of integration, and integrates the main circuit of the switching power supply into the chip, which can complete broadband modulation, isolation and various maintenance functions. As more and more people have higher and higher requirements for power modules and higher reliability requirements, I will share with you how to design safe and reliable power modules.

Do you know the main points of high-reliability power module planning?

4 elements of high-reliability power supply module planning:

1. Anti-surge maintenance circuit planning

How to plan the anti-surge maintenance circuit? For different applications, perhaps you can adjust the position of the Inductor TVS tube, which can make the system better use and use the circuit correctly, so as to better improve the EMC function. Pay attention to the planning of the two-stage anti-surge maintenance circuit. If used improperly, it will be counterproductive.

2. Reduce planning

Correctly control the components to the specified value, reducing the number of components can delay the degradation, improve the reliability of the components and improve the reliability of the power supply.

3. Dual power module planning

The output of the bidirectional power supply module should pay attention to the load balance. When planning, pay attention to the uniform adjustment of the output of the main and auxiliary circuits.

4. Component selection

The use of different components will result in different module functions. For example, ceramic or electrolytic capacitors are generally used for capacitor selection, while tantalum capacitors have long life, high temperature resistance, and good functions, but simply break the circuit. Please note that different products use different methods.
