The power module is a power converter that can be directly installed on the printed circuit board. According to the conversion method, it is generally divided into AC to DC or DC to DC. With the development of technology, power capacity tends to be modular and miniaturized, so power module appears. It has a high degree of integration, and integrates the main circuit of switching power supply into the chip, which can complete broadband modulation, isolation and various maintenance functions. With more and more people's higher and higher requirements for power supply module and reliability,
There are four elements in high reliability power module planning
1. Component selection
The use of different components will lead to different module functions. For example, ceramic or electrolytic capacitors are generally used for capacitor selection, while tantalum capacitors have long life, high temperature resistance, good function, but simple circuit breaking. Please note that different products are used in different ways.
2. Anti surge maintenance circuit planning
How to plan the anti surge maintenance circuit? According to different uses, we may be able to adjust the position of   inductor   TVs tube, which can make the system better use and correctly use the circuit, so as to better improve the EMC function. Pay attention to the planning of two-level anti surge maintenance circuit. If it is not used properly, it will be counterproductive.
3. Reduce planning volume
Correctly controlling components to the specified value and reducing the number of components can delay degradation, improve component reliability and power supply reliability.
4. Dual power module planning
The output of bidirectional power supply module should pay attention to load balance. When planning, pay attention to the main and auxiliary circuits to adjust the output evenly.
