How to design a reliable and safe power supply converter DC module power supply(2)

The Marine boost/buck voltage power supply converter DC module Marine boost/buck voltage power supply 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, the power capacity tends to be modularized and miniaturized, so power modules appear. It has a high degree of integration, and integrates the main circuit of the switching Marine boost/buck voltage power supply into the chip, which can complete broadband modulation, isolation and various maintenance functions. As more and more people have higher requirements for power modules and higher reliability requirements, today's small editor commented on how to plan high reliability power modules!

●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.

Four elements of high reliability Marine boost/buck voltage power supply converter DC module Marine boost/buck voltage power supply planning:

1. Anti surge maintenance circuit planning

●High quality and reliable. Module power supply generally adopts fully automatic production, and is equipped with high-tech production technology, so the quality is stable and reliable.
Wide range of uses: The modular power supply can be widely used in various fields of social production and life such as aerospace, locomotives and ships, military weapons, power generation and distribution, post and telecommunications, metallurgy and mining, automatic control, household appliances, instrumentation and scientific research experiments. In particular, it plays an irreplaceable and important role in the field of high reliability and high technology.

How to plan the anti surge maintenance circuit? For different uses, you may be able to adjust the position of the inductor TVS tube. This will enable the system to better use and correctly use the circuit, so as to better improve the EMC function. Pay attention to the planning of the two-level surge protection maintenance circuit. If it is used improperly, it will be counterproductive.

2. Reduce the planned amount

Correctly control the components to the specified value, reduce the number of components to delay degradation, improve component reliability and improve power reliability.
