How to design a reliable and safe vehicle power supply module(1)

The vehicle LED advertising screen power supply 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, 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 LED advertising screen 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 vehicle LED advertising screen power supply module planning:
